The steering rack is an integral part of any modern car, including Renault Logan. It is part of the steering mechanism and transfers power from the steering wheel to the steering linkage of each wheel. If you suspect a malfunction and the impossibility of adjustment, the replacement of the steering rack should be done as soon as possible. The procedure is not difficult and can be done by hand if you have a repair kit and know the rules for carrying out repairs.
On Renault Logan, depending on the release, steering racks of various types were installed - mechanical and hydraulic.
Cars of the first generation - phase 1 (2004, 2005, 2006, 2007,2008, 2009 model year) with a 1.4 engine in the two offered trim levels were equipped with a mechanical steering rack, and a car with a 1.6 liter engine was equipped with a hydraulic one. Restyled models (2009, 2010, 2011, 2012, 2013, 2014, 2015) and second-generation versions (2014, 2015, 2016, 2017) in the simplest trim levels are offered without power steering (power steering), which must be ordered separately ...
According to the manufacturer's instructions, the service life of the steering rack without any complaints about the quality is 180-200 thousand km, subject to regular preventive inspection.
Diagnostics of a malfunction is revealed by a simple inspection and careful attention to the behavior of the car on the road. The following signs will tell you about a close repair:
Sometimes the situation can be corrected if the part is adjusted, but this is not always possible. Often, adjusting the steering rack does not fix the problem, and then a replacement must be made: remove the old element and install a new device.
The weak link in the steering rack is the bearings and thrust bushings, which are the most common causes of inefficiency.
The steering block diagram is shown in the figure.
It is not difficult to independently perform work on troubleshooting the steering rack, the main thing is to determine the cause of the breakdown. On the net you can find many photos and videos detailing how to replace one or another element of the device.
Before installing a new homemade bushing, you need to sharpen it by correcting the size. Before placing the part, grease the seat. Assembly is carried out upside-down.
For troubleshooting, another method is used - you need to tighten the adjusting plug.
The problem of knocking the steering wheel is solved by adjusting the distance between the rack and the gear. In this case, it is enough to tighten the steering rack as much as possible, and the problem may disappear.
The adjustment features differ depending on the presence or absence of power steering.
Situations when, with the engine turned off, turning the steering wheel causes a knock in the steering rack, according to the manufacturer's instructions, do not require adjustment, although a special nut is included in the mechanism. After starting the engine, wait 10–20 seconds, and most of the noise will go away. Auto service specialists claim that this is an indicator of the normal operation of the power steering, and no intervention is required. If the problem persists, bend the tin washer (heat shield) before adjusting. This will save the car from the end of the warranty service. The washer fits snugly against the crankcase bolts. Sometimes you may just need to change the oil in the power steering.
In this case, you need a 10 hexagon. Algorithm of work:
Repairing and installing a new steering rack is not the most difficult process if you follow it strictly according to the instructions. A defect in work will lead to additional problems in management. When buying a new part, do not forget about replacing consumables, choose the right name and article for each one.
For more than ten years, Renault Logan has been successfully operated on Russian roads. High reliability, maintainability and cost have won the attention of a huge number of motorists. During all this time, the owners of Logans have accumulated considerable experience in the maintenance and repair of various parts and mechanisms of this car. This also applies to the steering, namely the steering rack, because symptoms in the form of knocking and crunching on cars of different years, appear periodically.

Front hub bearings and thrust bushings, according to statistical studies, are one of the weak points in the chassis of the Renault Logan.
These faults when driving are determined by the following criteria:
Some masters in car services, servicing such a malfunction, limit themselves to tightening the adjusting plug. However, the manufacturer categorically does not support such repair methods and prohibits them from being carried out. Explaining this by the fact that the gear-screw (worm) transmission, with an excessive tightening torque, begins to intensively wear out the teeth on the gear, which in turn leads to even greater malfunctions.
But then what to do in such a situation? You will say! Because in case of obvious malfunctions, a complete replacement of the steering rack cannot be dispensed with, and the price bites very much in the current economic situation.
The price for a new steering rack for Renault Logan "bites"
In such a situation, experienced Renault Logan owners propose to carry out such repairs on their own with their own hands. By stipulating that everyone should rely either on their own strengths or that it is best to repair under the supervision of a knowledgeable master.
The table below shows the most common breakdowns on the Renault Logan steering rack and ways to solve them:
In this article, we will consider the Renault Logan steering assembly. Many Logan owners are interested in the Logan steering rack, the purchase and replacement price. But perhaps you only need to adjust or repair the Logan steering rack without gur or with gur. You can find out how to diagnose and repair the steering Logan from this article, as well as by contacting our car service with this question.
The steering rack of a car, including the Logan steering rack, is a reliable, durable assembly that rarely deforms and breaks. But constant loads (torsion of the steering wheel) can damage the part, which leads to the need to repair the Renault Logan steering rack, or the Logan steering rack needs to be replaced. The process of restoring the steering component in most cases turns out to be meaningless, therefore many are interested in the Renault Logan steering rack the purchase and replacement price.
And although the Renault Logan steering rack with gur is one of Logan's weakest points (if the steering rack is Logan without gur, it will last longer and more reliable, since the design is less complicated), but do not rush to immediately buy a Logan rail. The technicians working in our car service have extensive experience with the presented malfunctions, and perhaps repairing the Logan steering column will help you, or you only need to replace the Renault Logan steering rack boot or oil seal.
In any case, we recommend that you first make a diagnosis of the Renault steering rack in a car service to save time and money.
Consider the constituent details:
Tie rods and tips, which are responsible for turning the wheels, are attached to the retractable mechanisms of the part.
A toothed bar with gears is responsible for transferring power from the steering wheel to the traction, and controls the wheelset.
The body (crankcase) is a component made of aluminum, inside it contains all the main mechanisms of the rail.
The spring system ensures a snug fit of the rack to the gears, and also relieves the steering wheel of free movement, backlash.
Limiters regulate the maximum value of the steering wheel turns to the left and right sides.
Bearings - used for ease of manipulation when turning the rack.
Despite the high strength of the mechanism, it often undergoes accidental deformations, which can ultimately damage the part completely, and in this case it will be necessary to replace the Renault Logan steering rack.
Here are a few of the main symptoms that indicate a malfunctioning Renault steering unit, one of the most important parts of a car:
A characteristic knock when manipulating the steering wheel.
The steering wheel becomes tight, or turns only in one direction.
An incomprehensible hum in the power steering is also a signal that it is time to diagnose the rail.
After long periods of parking on the asphalt, large oil stains remain under the car, symbolizing leaks in the component mechanism.
There are several main factors that negatively affect the integrity and performance of the steering assembly as a whole:
Accidental hitting into holes, hitting curbs or serious bumps, traveling on uneven, dusty roads - all this can disable a part in a matter of months.
Cold: Many drivers using the car in winter forget to turn the steering wheel left and right a few times before starting to drive. This procedure is necessary for the rapid heating of the HG liquid, which has a certain operating temperature.
Untimely replacement of the aforementioned fluid also becomes a frequent breakdown problem.
A negligent attitude towards periodic inspections and diagnostics of the steering unit can leave small cracks and leaks unnoticed. The neglected state of the deformation of the rails can lead to a complete malfunction of the part, and therefore it will be necessary to replace the Logan steering rack without gur or with gur.
General inspection of the steering assembly is carried out as follows:
The work is done in pairs. The foreman examines the underside of the car, asking his partner to gently rotate the steering wheel in different directions. Thus, a certain position of the steering wheel is found out, at which a knock is noticeable.
If leaks occur, the boot is inspected.
Diagnostics in the service station can be carried out with a complete disassembly of the steering assembly. In some cases, the Renault Logan steering column is repaired, in other cases it is required, for example, to replace the Renault Logan steering rack. It depends on the nature of wear and neglect of the steering unit.
Because of this, experts often advise drivers to listen to their car, since any extraneous sound is a signal that certain parts are out of order, broken, or detached from the right place.
Renault Logan steering rack adjustment relieves the general steering system from backlash and knocking, which become the main causes and symptoms of malfunction. In the process of debugging the steering rack, special keys and screwdrivers are used to quickly get to the desired nut, with which the part is adjusted.
Since the nut is under the hood, the car rises in the service center in order to open the steering column space for the master. Alternatively, a garage pit is used.
At the first adjustment, the nut can be closed with a special plug, which can be easily removed by prying it off with a screwdriver.
If the element is overly "stuck", i.e. its stroke does not lend itself to an ordinary key, the craftsmen resort to the help of a hammer and a special lubricant, which facilitates the movement of the nut along the thread.
Repair of the Logan steering rack without a power steering or with a power steering is carried out after removing the steering rack for its subsequent restoration.
List of further operations:
Removing the retaining ring from the distributor is the first step in the repair process.
Further, the spool plug is unscrewed, covering the spool nut, which is subsequently also unscrewed with a special device.
The adjusting clamp nut is removed after.
Next, the clamp spring is removed, as well as the clamp itself.
The distributor, hidden in the housing, is removed by knocking out.
Next, the oil seal is removed from the distributor, as well as the bearing ring, which breaks in most cases.
The retaining bracket is removed from the rear support. When prying on with a screwdriver, it flies out by itself.
Next comes the back plate and the stock.
When the Logan steering rack is completely disassembled, all its components are qualitatively cleaned of oil, dust, as well as possible wear products. Degreasing is performed.
The surface of the rod must be ground on a lathe with fine emery paper. The distributor shaft is also ground.
The preparation of the components is over. The comb of the stem is thoroughly lubricated with grease before being returned to its place. All oil seals are pre-replaced.
Checking the compression of the stuffing box is a mandatory step before returning the valve. A special sliding sleeve is shifted along its shaft, which fits into the place of the bearing. The new distributor oil seal is seated in the same way. All elements are thoroughly lubricated with grease.
Then the retaining ring returns to its place.
The stem clamp is installed after. Its place is completely filled with lubricant to facilitate movement.
Then a spring is installed, which is fixed with an adjusting nut.
The rear support is equipped with a centering support, after which the oil seal and the rear support itself are shifted along the rod. The element settles securely.
The retaining bracket returns to its place.
When the work is completed, the Logan steering rack is checked using a special machine that helps to identify possible leaks, and also provides a guarantee for the restoration carried out.
Steering rack failure is an important issue among motorists. Many are interested in the Logan steering rack the purchase and replacement price, often they ask us "Logan rake with gur price", less often they search for "Logan steering rack without gur price", someone is interested in how the Renault Logan gur steering rack is repaired, some are worried about repair steering column Logan. In any case, in order to delay the appearance of such questions, it is worth listening to the recommendations of the masters and owners of Renault Logan.
Here are some tips highlighted from the personal experience of the average driver that will help you protect the steering assembly from premature wear and damage:
You never need to turn the handlebars all the way out - this will reduce the force applied to the rack, which will significantly reduce the risk of wear.
The anthers of the steering rods should be treated with extreme caution - their breakage or defect can lead to fogging of the rack mechanism, which causes the GU fluid to leak.
The steering rack needs to be warmed up in the cold season in the same way as the engine.
Self-checking the condition of the steering assembly largely depends on the quality of the fluid poured into a special tank. It must be clean and transparent. With any kind of turbidity or the formation of foreign bodies, the liquid is replaced.
Despite the high strength of the described mechanism, one should be careful about diagnosing the Logan steering rack, which is better carried out in a service station. In the process of self-examination of the steering unit, you can lose sight of many small parts, which together can quickly disable all elements of the steering rack or steering column.
This once again speaks of the need for qualified assistance during the operation of the car, since this approach provides not only comfort, but also safety during driving.

The Renault Logan steering rack is a special mechanism that transfers forces from the steering wheel to the steering rods of each of the wheels. In other words, it is a device that makes the front wheels turn in the direction that the steering wheel turns.
Despite the apparent reliability, the unit breaks down from time to time, requires replacement and subsequent adjustment. How is Renault Logan steering rack repair and adjustment carried out? What nuances should be taken into account? Let's consider these points in more detail.
VIDEO
According to the manufacturer, the resource of the steering rack is 180-200 thousand kilometers. To avoid malfunctions, it is enough to inspect and, if necessary, revise (repair) the unit at least once every 6 months.
There are many reasons for the failure of the node. Here are just a few of them:
Poor quality of roads, which increases the load on the junction.
Accumulation of dust and dirt in rubber seals with subsequent corrosion.
Reckless driving style.
Normal wear and tear and so on.
How to determine if a Renault steering rack is faulty? Often, a routine inspection, as well as attention to the vehicle while driving, is enough to identify a defect. The first signs that in the future it is impossible to do without repair or adjustment are the appearance of extraneous noise, an unusual knock of the suspension, an increase in wheel play or a stiff steering wheel. In such a situation, the best solution is to contact the service station to find the problem, and subsequently to repair the front suspension using a repair kit. In some cases, it may be necessary to replace a failed unit.
According to statistics, the weakest link in the Renault chassis is the bearings installed in the front hubs. Not less often, motorists also complain about other components - thrust bushings, which are damaged due to poor-quality road surface. We mentioned the first signs of breakage above (knocking, vibration and increased backlash when turning the steering wheel). Consider the malfunctions and features of Renault repair in more detail.
Breakdowns and methods of elimination:
Many craftsmen go the simplest way and solve problems with the steering rack by pulling the adjusting plug.
But if you squeeze the worm-type gear too much, the teeth will wear out, which can cause many troubles in the future. But in a garage, there are not so many other alternatives to repairing a Renault rail.
If a knock is heard when the steering wheel rotates, then its source, as a rule, is the steering rack due to a loose fit to the gear. One of the elements of the mechanism is a thrust nut, thanks to which the distance between the gear and the steering rack is adjusted. If you tighten it, then the problem is most often solved.
“The main thing when doing this kind of work is to be careful and not overdo it. If set up incorrectly, the risk of wear and tear of worm assemblies and their failure grows. "
To tighten the nut or repair a failed unit, take into account the design features of the car. There are two options here:
Power steering is provided on Renault Logan. Consider the situation - the engine is off, and when turning, the steering rack knocks. Take your time to make adjustments. On a car with a power steering, a special nut is present, but it is not recommended to rotate it (as mentioned above).
Start the engine and wait at least ten seconds. The activity of extraneous noise during the rotation of the steering wheel is most often reduced. Experts assure that this is the normal work of the GUR. If this happens, do not touch the Renault steering rack nut and continue to operate the machine.
If the problem persists, bend the "tin" washer before stretching the nut. Thanks to this foresight, the machine remains under warranty service. Please note that the washer is riveted around the perimeter of the nut and is close to the crankcase bolts. In some cases, a repair kit may be required (for more serious work) or the usual fluid replacement in the hydraulic booster. The latter option is relevant if the working fluid has not changed for a long time, and its properties have deteriorated.
The principle of operation is to turn the nut to the right side to reduce the clearance. The work on adjusting the Renault rail is done as follows:
Park the car in the hole and raise the handbrake to secure the wheels.
Dismantle the crankcase protection using a ten key (you will have to twist three pairs of screws). One cannot cope here - take a partner with you.
The recess in which the nut is installed is tightly closed with a plug (made of plastic or rubber) - remove it. Please note that it is not always possible to see the nut itself - find it by touch.
After removing the plug, you have several options. Use a flex or L-shaped wrench. In the latter case, the length of the handle should be ten centimeters or more. Alternatively, buy a special key.
Jack up the wheel on the left side to reach the nut and remove it.
“Some people make grooves 100 * 100 mm before broaching the steering rack with an angle grinder. This is a dangerous technique and it is better to refuse it. "
Next, proceed with the adjustment. For this:
Turn the nut to the right by a small angle (15-20 degrees).
Command your partner to actively steer left and right.
Broach again if knocking occurs.
After the knock disappears, do a test pull for another 10 degrees.
If you follow the instructions carefully, adjusting the Renault rail will not take much time. But keep in mind that if a malfunction is found, it may be necessary to replace the faulty unit (here you can no longer do without a repair kit). If some points remain unclear, watch the training video.

Replacing the steering rack on the Logan can be done in a garage, with minimal effort if someone helps you with this. In the video, you can clearly see how to change the Renault Logan rail without having much experience in car repair.
To dismantle the steering rack you will need:
jack up and hang out the front of the car;
drain the power steering fluid;
unscrew and remove the steering tips;
unscrew the steering column cross from the passenger compartment;
unscrew the muffler (remembering to disconnect the lambda connector) so that it does not interfere with lowering the subframe;
unscrew the 4 bolts securing the subframe and the lower engine mount;
unscrew the power steering tubes from the Logan steering rack;
unscrew two more bolts securing the rail to the subframe, it will finally be possible to remove it and put a new one.
Having installed the steering rack in place, it is unforgettable to fill in new power steering fluid and bleed the system from air.
If a mechanic is installed, due to its simpler design, the steering rack can last longer. Since some of the breakdowns can be associated with hydraulics. But these cars are a minority. Renault produces the latest models only with amplifiers (both hydraulic and electric). However, there are also cars without amplifiers, including rarities, and cars with the power steering removed.
The general design of the part is as follows:
Rotation of the front wheels is provided by rods with tips, which are connected to the retractable mechanisms.
From the steering wheel to the rods, the force is transmitted through the gear and the toothed bar.
The rack is pressed against the gear and the spring mechanism is eliminated from the backlash.
The Logan rail body itself is made of lightweight and durable aluminum.
The bearings provide freedom of rotation, and the limiters adjust the maximum degree of rotation.
Among the signs of failure of the control mechanism are:
knocking while driving a moving car;
difficult movement of the steering wheel in both or one of the sides;
a big backlash is felt;
in the presence of power steering - hum, as well as amplifier fluid leaks.
Among the factors affecting the performance of the node, there are:
Extreme temperatures. Frosts have a particularly negative effect on the condition of the slats. In order for the power steering fluid to warm up, you need to turn the steering wheel in different directions before driving.
Bad roads: many holes and potholes, deep ruts, dust.
Lack of power steering fluid and oil.
Deformations due to impacts while driving or illiterate repairs.
Defect or installation of a steering rack that is not suitable for its characteristics, as well as its elements.
Late maintenance, diagnostics and inspections.
General aging of the mechanism (depletion of a resource, after which it is necessary to replace parts).
The diagnostic procedure includes:
superficial inspection of the state of the mechanism (including the presence of a leak in the rack with power steering);
determination of the knock site (check is carried out in tandem with an assistant);
checking the backlash angle.
All these works are carried out without removing the rail from the car. If any problems are found, it is completely dismantled. Inspection is also carried out, and stands are used for testing, simulating real loads.
do not require major repairs;
not caused by the breakage of any rail element.
It is possible that you need to replace the boot or oil seal, that is, your costs will be minimal. True, it is impossible to pull with their replacement, otherwise the repair will be longer, more laborious and expensive, or even lead to the need to replace the assembly.
There are also cases when replacement is not required, but also repairs in general, when the rail only needs to be adjusted. This procedure is carried out without removing and disassembling the unit, right on the car, and can get rid of a slight backlash or knocking. It does not take much time, but only if given experience and conditions. To get to the adjusting nut, you need to open the steering column space. And the adjustment itself is associated with turning the steering wheel, that is, it is also carried out by the master in pairs.
Repair is quite possible if the condition of individual elements allows them to be replaced without installing a new rail assembly. The wizard performs the operations described below. On the car, the tips, the shaft, the pallet, the fastening of the rail to the body are disconnected. In a vice, the stopper, plug and nut of the spool, hold-down springs and distributor are successively removed. The oil seal, bearing, retaining bracket, back plate and stem are removed.
Consumables are replaced (anthers, oil seals, bearing).
The steering rack is assembled and installed on the vehicle in the reverse order.
Adjustment and testing is in progress.
The power steering fluid is replaced; at the slightest damage to the reservoir, it must be replaced.
The cost of a car with a rack without a power steering is much lower than with it. This captivates those who are not overly concerned about driving comfort. And it becomes not so convenient without hydraulics.
The process of replacing a steering rack without power steering is almost similar to the procedure for repairing a part without an amplifier. When changing, it is removed and dismantled in the same order. Disassembly, cleaning, grinding, lubrication are also carried out. Only the stages during the replacement are still somewhat less: due to the simplified design, they can only consist in the refinement of the mechanism.
Taking into account the fact that the rack is about three times cheaper without power steering, some motorists have a question - is it possible to install it on a car that is designed for a power steering? Most often, this question arises from owners of used cars who do not want to invest significantly in repairs.
the line is closed for oil circulation;
a short belt is installed;
the steering column is being redesigned.
The dispute about which is better: with or without power steering, that is, cheaper or more convenient, has long flared up on the Internet between motorists. Craftsmen are advised to pay attention to the presence of analogs - they can significantly save money without losing comfort. Although, in any case, the driver himself should choose, and our specialists will do everything to return the car to the best handling.
The main disadvantages of self-repairs, which hardly anyone would argue with, are:
waste of personal time;
search for the necessary spare parts and materials for work (not the fact that they are optimal in terms of price and characteristics);
lack of guarantees of the quality of repair or replacement of the unit (without experience, it is easy not to notice any minor problems).
