Steering rack Renault Logan with gur DIY repair

In detail: Renault Logan steering rack with gur DIY repair from a real master for the site my.housecope.com.

Let's say a knock is heard when you turn the steering wheel left and right. This knock can also occur when driving on a bad road. And the sound itself in each case will be emitted by the rack, loosely adjacent to the gear. A nut-stop is always screwed into the crankcase of the steering mechanism, tightening which reduces the gap between the rack and the gear. In general, the Renault Logan steering rack tightening looks the same as in other cars - the nut must be tightened, while it is advisable not to overdo it.

The car is in the pit;
The engine is off;
The rack makes a knock when turning the steering wheel.

Don't rush to adjust! There is indeed a nut in trim levels with power steering, but it will be undesirable to turn it.

Two power steering hoses are clearly visible

Try to start the engine and wait 10 seconds. The intensity of all knocks made when turning the steering wheel should decrease. This is how the power steering works, and this is normal! You can safely continue to operate the car.

Before tightening the steering rack of Renault Logan with power steering, always bend the tin washer. The warranty is then lost. The washer is riveted along the edge of the nut and rests against the sides of the crankcase. Sometimes replacing the fluid in the power steering helps, but only if it has not changed for a long time and has lost its properties.

Let's see what the steering rack mechanism looks like live. The nut is located under the arrow (see photo).

Here is the stop nut

The nut itself can be turned with a hexagon "by 10". It's simple: rotation to the right corresponds to a decrease in the gap.

The car will have to be driven into a hole - there are no other options. Secure the rear wheels with a handbrake.

Two nuts on each side

First you need to remove the crankcase protection. We take the socket wrench "10" and unscrew 6 screws (2 on each of the three sides). It will be difficult to do without an assistant here.

The recess in the nut will be closed with a plug, rubber or plastic. The plug must be removed.

Nut location circled

The nut itself is not visible from under the bottom. Find it at the point surrounded by a circle (see photo).

The location of the nut must be felt by hand. This is how the steering rack of Renault Logan is tightened, as well as Lada Largus and all VAZ novelties.

When the nut is found and the plug is removed, the following options are possible:

We use an L-shaped socket wrench with a handle less than 10 cm;
A "flexible key" is also suitable, which is held over the metal of the body (see photo);

Here the key rope is passed

You can buy a special Renault / Largus key.

To reach the nut, it will be easier to jack up the left wheel and remove it. Next, a socket wrench is used.

And even before tightening the Renault Logan steering rack, many do this: they make a "10 by 10 cm" notch in the bottom with a grinder. It is better not to use this method.

Of course, it's best to do all the work with an assistant. The rail is adjusted step by step:

The nut is turned to the right by 10-20 degrees;
Let the assistant turn the steering wheel;
If a knock is heard, carry out step 1.

In the last step, the nut is tightened by turning it another 10 degrees. We wish you success.

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.

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 table below shows the most common breakdowns on the Renault Logan steering rack and ways to solve them:

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.

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.

Breakdowns and methods of elimination:

“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:

If Renault is without power steering, the situation develops according to a different algorithm. In this case, you will also need to rotate the nut with a hexagon to "ten".

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.

The controllability of any car depends on the state of this part. On Renault Logan, the rake can serve a variety of periods - from 30 to 200 thousand kilometers. Both of these figures can be brought under extreme values, depending on the operating conditions.On average, the owners turn to our car service with problems of the steering mechanism (from knocking to complete imbalance of the shaft) through a hundred thousand.

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:

Sloppy driving style: non-observance of the speed limit that meets specific road conditions, turning the steering wheel to the extreme position for more than 5 seconds, starting driving in the same position, high-speed collisions on hills (curbs, speed bumps, bumps, etc.).
Extreme temperatures. Frosts have a particularly negative effect on the state 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.

There is no need to rush to look for a steering rack or contact a car service if there are any signs of its failure. Our craftsmen regularly face problems that:

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.

Cleaning of dust and traces of wear, degreasing, grinding of the shaft on the machine, lubrication of the bar is carried out.
Consumables are replaced (anthers, oil seals, bearing).
The steering rack is assembled and installed 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 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 practically 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.

When removing the amplifier, the question arises of excluding its pump from the general system. In this case, the options are used:

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 analogues - 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 will 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 to miss any minor problems).

In our car service, repair and replacement of the steering rack is aimed primarily at the comfort and safety of motorists. Diagnostics and work are carried out in a short time and at low prices. And the quality is guaranteed.

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, because 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.

The part can be either mechanical or hydraulic. The latter type of construction is especially common on modern cars, as its architecture is more perfect in terms of assembly and also provides a more comfortable driving experience. The third type of steering rack is called electric (EUR). The EUR mechanism has a complex design and high cost in relation to its hydraulic counterpart.

Consider the constituent details:

The steering 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 system of springs ensures a tight 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 determined, at which a knock is noticeable.
