It should be noted right away that while the chassis is being repaired, only ball bearings will not be unscrewed.
Next, unscrew the stabilizer bar (it is enough to do this only from above) and the steering tip.
Megan's rack and pinion mechanism is very sensitive to our roads, as a result of driving on them, a knock occurs. If a car driver uses an aggressive driving style, regularly accelerates quickly and brakes sharply, Renault Megan will not tolerate such an attitude and will quickly let its owner know about it. Therefore, use the repair kit in a timely manner.
The first and second generation Megans use rack and pinion in the steering mechanism.The design is represented by a rack bar of a sufficiently large length, which moves with the help of a pinion gear, causing the movement of the wheel.
If there is additional noise in the form of knocking when driving, especially on a bumpy road, it can be said with certainty that this is the knocking of the steering rack bushing. Definitely the bushing needs to be replaced. Before the repair procedure, you should stock up on the necessary components and tools, as well as study the corresponding video in detail. The repair kit will help to repair minor malfunctions.
In case of doubt about the malfunction of the rail, you should start from the video in your research in order to understand where and how the knock occurs.
To eliminate knocks and replace the rail and related parts, including replacing the bushing, a repair kit is used. The minimum set of spare parts and tools included in it: gearbox, lubricant (lithol, salidol, VD-40), a set of wrenches, gaskets and seals.
The basic Renault Megan 2 repair kit is not a cheap pleasure, so you can use an analogue from other foreign cars. However, before use, you should consult with a car mechanic who will tell you whether the toolkit is suitable or not, and what should be added to it.
An assistant is needed to replace the steering rack bushing. For repairs, a small gas key is used; a larger one will not fit through. To save money, it is worth making your own undercut of the steering rack bushing. To do this, use your own or existing drawing with applied dimensions.
Subject to technology, if the replacement of the sleeve was correct, knocking will not be observed. In case there are doubts, you should fix the main points that were shown in the video instructions.
With severe wear of parts, the repair kit is not useful, since you will have to change the entire assembly in the complex. The Renault car concern advises motorists to use only the original repair kit. This ensures that all consumables fit exactly and fit perfectly into place.
To replace the entire structure, you will have to abandon the use of a repair kit.
You can find a lot of videos on the network that allow you to find out the location of the nuts and bolts on Renault Megan 2. There are also many videos that clearly show how the steering rack bushing changes.
It is not surprising that in domestic road conditions an extraneous knock occurs on the Renault Megane 2 rack and pinion mechanism, because it is quite sensitive. With a sharp change in driving style, the main components of the Renault Megane 2 will quickly fail. Therefore, to restore it is necessary to use a repair kit. Replacing the bushing and the subsequent elimination of noise is not a difficult task, and it is quite within the power of the driver with an assistant.

To solve this problem, the officials suggest replacing the rail assembly, which is very expensive, about 21,000 rubles. for the original, 11000 rubles. for not original.
The cause of the problem is a small plastic sleeve in the rail on the right. a rail goes inside it, the sleeve breaks and play begins.
Because The Renault factory did not provide for the replacement of this bushing; accordingly, it does not produce a repair kit for replacement. The ZF bushing from a BMW car is ideal for the rack rail (I don’t know which model). The catalog number for the order is 7820 023 188, the cost is 81.61 Russian rubles. A little less than the cost of a new rack)
(the photo shows rubber bands, which I bought separately, later removed, because they were not needed)
So, in order:
2) unscrew the steering knuckle nut
7) turn the steering wheel to the extreme right position. now you can see the bushing
15) enjoy the silence of the rail and the absence of backlash
The work took 2.5 hours, there were no serious problems.
A few tips: it’s better to work together: there are many moments that are very difficult to do alone ... It’s better not to remove the left wheel (some remove it to make it easier to turn the steering wheel) in order not to accidentally twist the steering column cable, which can lead to its breakage, I still broke the cable, had to solder
You need to take a small gas wrench to unscrew the steering rod - a large one will not fit through. get ready for the fact that you have to gouge with installing a new bushing in the mounting hole: on the rail body there is something like a semicircular strip, on the bushing itself there are two plastic ears, you need to get your ears into this strip.To do this, you need tweezers or pliers with long sharp noses (for squeezing the ears) and something like a long screwdriver (for pushing the sleeve in). seems to be all
UPD: on a run of 170,000, I still repaired the rail at the service, because. broke the bushings not only on the right, but also on the left, in the area of \u200b\u200bthe electric amplifier
Replacing the steering rack bushing on a Renault Megane II can be done on its own. It will take about three hours to complete the work. You won’t have to spend much, which naturally can be considered positive news in a difficult financial situation.
In fact, there are a number of signs that are indeed quite telling.
– When the vehicle is driven in second or third gear on poor quality roads, the driver may clearly hear a knocking noise.
Usually, the problem really lies in the sleeve, which is time to be replaced. But do not exclude the option that the entire rail failed. In any case, before spending a significant amount, it is better to spend a few hours of free time. Suddenly, you will be able to get off with a fright.
What can't be done without? Unfortunately, the engineers working at Renault expected that the rail assembly would be replaced, and not its individual parts. Therefore, you should not look for a repair kit, because this makes no sense. Domestic mechanics have already found out that in this case, a similar part from BMW is perfect. She has a personal number in the catalog, and it is designated by two letters - ZF. The cost of such a part is not high - less than a hundred rubles. You can find it in any salon or on the Internet.
Well, if there is an opportunity to use the pit. Otherwise, you will have to search for a flyover or just crawl under the car. If you had to use the latter method, then you should take care of your own safety. It would be worth putting bricks under the wheels so that the car would not drive off.
1. The front of the vehicle is raised with a jack. If necessary, you should use insurance, which is used as wooden substrates, so that the car does not break and crush the person under it.
2. The right wheel is being dismantled.
3.A nut is twisted from the steering tip, which makes it possible to disconnect it. It happens that the fasteners are dry, then WD40 comes to the rescue. Carefully turn the steering wheel all the way to the left.
4. Cut off the clamps from the anther. The factory put plastic, they should be changed to metal.
5. The lock nut is unscrewed. After it - the turn of the tip, and then the anther itself.
6. Take an adjustable wrench and put it under the power unit, and then under the lower suspension arm. The person below must pull the key towards themselves. The one who is on top must constantly put the key in the correct position.
7. Turn the steering wheel to the right to the limit. The bushing will be clearly visible.
8. You will need a long screwdriver, with which the part can be removed. To facilitate the task, the assistant should turn the steering wheel to the left and to the right.
9. When the bushing is too worn, when pulled out, it can simply fall apart into small pieces. It's not hard to get it. It is important that none of its parts remain inside the mechanism.
It's not as difficult as it is inconvenient. Again, do not do without an assistant. He will have to twist the steering wheel from side to side so that the sleeve falls into place. The bushing can be lubricated with a special grease or with lithol. On this, such a procedure as replacing the steering rack bushing with a Renault Megane II is completed. For reliability, it is recommended to drive to the service station to make the wheel alignment.
The new rail will provide complete silence in the car. If on a difficult road there was an unpleasant sound and recoil in the steering wheel, then the new Renault Megan 2 steering rack will significantly improve the situation. How to determine that the Renault Megan 2 steering rack needs to be replaced? The main symptoms are a dull knock from the front when driving over uneven surfaces at low vehicle speeds. Also, the inability to set the convergence, which is due to the backlash of the rack on the right. A fairly dull knock with a quick short swing of the steering wheel to the left, to the right in an immovable car.
You can replace the Renault Megan 2 steering rack with a ZF bushing from a BMW car, which is well suited to this car model, because a Renault factory bushing is not provided. In addition, a new tie rod lock washer assembly may be required.
At the beginning, you should unscrew the wheel, right in the direction of travel. Next, unscrew the nut of the steering tip, disconnect it. Then the steering wheel is unscrewed to the extreme left position, the plastic clamps of the rack anther are cut off, the locking nut of the tip is unscrewed, then the tip itself. The rack boot is removed.
With the help of an adjustable wrench, the thrust is unscrewed. Further, when replacing the Renault Megan 2 steering rack, the steering wheel turns to the extreme right position. The bushing is pry off with a screwdriver. It is necessary to shake the steering wheel until the sleeve comes out - it may break. Next, a new bushing is put in, grease is packed in, the rod is screwed on, and the rod hinge can also be lubricated. Next, put the boot in place, tighten it with clamps, screw the steering tip to the rod and lock it with a lock nut.
The tip is screwed to the steering knuckle, after which the wheel is installed. The job will take about two and a half hours. It does not cause any particular difficulties. But here it is more convenient to work together. In addition, in order not to damage the Renault Megan 2 steering rack, use a special wrench (Dir. 1305 No. according to the Renault catalog) and a rack mounting clamp (Dir. 1306 No. for the SMI steering rack or 1306-01 for the TRW rack).
First of all, remove the wheel. Next unscrew the steering knuckle nut
We turn the steering wheel to the extreme left position, cut off the plastic clamps of the rack boot.
We unscrew the counter nut of the tip, unscrew the tip, remove the rack boot
We turn off the thrust with an adjustable wrench (to do this, we put the key behind the lower suspension arm under the engine, one person pulls down while in the pit, the second one sits in the wheel arch and adjusts the gas wrench after each turn
Next, we unscrew the steering wheel to the extreme right position, which will give us the opportunity to clearly see the sleeve.
now we pick the sleeve with a long flat screwdriver, at this time the assistant should shake the steering wheel left and right until the sleeve comes out.
In our case, the sleeve broke easily, so we had to get the rest.
We put in a new bushing, I had to tinker a bit.
Faschiruem lithol lubrication.
We fasten the rod, lubricate the rod hinge just in case.
We put the boot in place, tighten it with clamps, fasten the steering tip to the rod and lock it with a lock nut
We fasten the tip to the steering knuckle, then put the wheel.
We assemble in the reverse order.
Main symptoms which indicate a tired steering rack bushing - these are: a strong thud from the front when driving through bumps at low speed, the presence of rack play on the right and, as a result, the inability to set the convergence normally, “fuzzy zero”, that is, at more or less high speed, the steering wheel does not return to zero position, as well as a thud with a quick short swing of the steering wheel left and right while the car is stationary. This photo report shows in detail how do it yourself replace steering rack bushings by car Renault Megane 2 .
The design of the car consists of many different technical elements. For its normal and trouble-free control, it is necessary that all of them be as serviceable as possible. The Renault Megane 2 steering rack, like the rest of the controls, requires regular maintenance and technical monitoring.
The Megan 2 steering rack is not the most complicated device, it will not be difficult to understand the design features. The only thing is that Megan 2 steering rack repair will require certain knowledge and skills that usually only employees of a specialized car service have. Without knowing all the features of the device and maintenance, the repair of the Megan 2 rail may not be of sufficient quality and lead to even more damage. Professional repair will be more reliable and will give confidence in the stable operation of the rack and pinion mechanism.
The Renault Megane steering rack has the same symptoms as most of the racks of other cars of this class.
The primary symptom is a knock in the steering wheel when driving. At first, you can not pay attention to it, but over time it intensifies and creates a certain discomfort.
It can also be an uneven distribution of force on the steering wheel, or its absence at all, play and other signs. On rough roads, these faults come to light especially clearly.
During operation, it is necessary to regularly monitor the technical condition of the car. The Megan 2 steering rack has the same causes of malfunction as the racks on other cars. Often, the reason is driving on a bad surface, which is very important in conditions of not very high-quality roads and, also, due to careless driving.
Knocking may occur, most often, if the fasteners have become loose due to prolonged use. It appears if the bushing, anthers, or rack teeth are worn out. And it happens that the sleeve is made of insufficiently durable material, which, due to intensive use, quickly loses its original properties. It could also be natural wear and tear.
A tight steering wheel also indicates the cause of the breakdown and that Renault Megan needs steering repair.Here, the cause may be the incorrect operation of the steering tips, or the EUR. Some parts need urgent replacement!
Before proceeding with the repair of the car rack, it is necessary to examine the vehicle for other related faults. It may be a malfunction of the chassis of the car, or something else. Thanks to this, it is possible to identify the alleged cause of the breakdown and prevent future ones.
Starting the diagnosis, the Renault Megan car rail must be cleaned of old dirt and carefully inspect all the details of the mechanism. O-rings and seals are subject to mandatory replacement, the shaft is examined for integrity.
If any part of the steering assembly fails, it makes no sense to restore it. Most of them are produced mainly as consumables. For example, tie rods with anthers, seals with hinges and other parts. If this is not done, then the effect of the repair may be short-lived and there is a risk of an early breakdown.
Often you have to change the entire Renault Megan rail due to its heavy wear and the risk of a more serious breakdown.
Renault Megan 2 steering rack repair requires special knowledge and skills, as well as a suitable professional tool. Therefore, it is not possible to carry out repairs correctly, not only on your own, but also not in any car service.
When repairing the Renault Megane steering rack, you will need a set of necessary components. It is better to use high-quality and proven materials that the master from the car service will recommend.
You will need a whole set of keys, pullers, measuring instruments for more accurate diagnostics and, in fact, a stand for the final check of the entire mechanism assembly.
All this is available in our specialized car service, where they repair the steering racks of cars.

It is unlikely that it will be possible to do without replacing oil seals and seals in the process of repairing the Megan 2 rail. Is the drive of the hydraulic booster leaking, are the tips - seals misaligned, in order to avoid additional problems, it is better to change them for new ones. They are inexpensive, fall into disrepair quickly enough - so your car will not be worse from this.
In many cases, the repair required by the Renault Megane 2 steering rack is limited to just replacing the sealing elements. This is if a malfunction is detected in time. So, getting sand or pebbles from the road can lead to more serious damage.
In fairness, it should be said that the complete absence of steering play is possible only in theory. In practice, a small “free play” of the steering wheel is present in every car. It is important to ensure that the value of this move does not increase over time.
To find out the cause of the backlash and eliminate it, the master will have to disassemble the rail by screws, scrupulously examining all the movable joints. Usually the cause of the backlash is a change in the geometry of the rail parts, which has arisen due to their wear. Despite the fact that all parts of the steering mechanism are made of extra-strong materials, there is no such steel that would serve forever.
Another reason for the occurrence of backlash can be a breakdown of the rail as a result of its mechanical damage by a foreign object. All this, again, is a consequence of a violation of the tightness of the casing. In this case, it is possible (but not necessary) that a rattle, crackling or knocking sound occurs when the steering wheel is turned.
The design of the Megan 2 rack is such that even if one tooth is missing on it, the car does not completely lose control: the steering wheel does not wedge, the car does not drive from side to side. Only in one of the sectors of its rotation there is a significant backlash. However, driving with such a serious malfunction becomes very dangerous. Therefore, it should be delivered to a car service on a tow truck.
Of course, breakage, deformation, wear of the rail, as well as damage to the tips, is a reason to replace them. Install only Renault branded spare parts on your car - components of other spare parts not certified by the car manufacturer may, firstly, not fit perfectly into place and thereby cause backlash, and secondly, being made of less durable steels, quickly subject to wear, so that the repaired rail will not last long.
As you can see, in most cases, a failed Renault 2 steering mechanism can be repaired. A complete replacement of the rail is required only when at least 70% of its components have been worn out. Then its repair becomes impractical from an economic point of view. On the practical side, a new part is always better than the old one, and if you see that the component rails have begun to slowly fail, it makes sense to fork out once and replace the entire mechanism at once. So you will be sure that you will drive the next hundred thousand kilometers without problems.
