It should be noted right away that while the chassis is being repaired, only the ball joints will not be unscrewed.
Next, unscrew the stabilizer post (it is enough to do this only from the top) and the steering tip.
The Megan rack and pinion mechanism is very sensitive to our roads, and 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 long length, which moves with the help of a drive gear, causing the wheel to move.
In the event of additional knocking noise when driving, especially on a bumpy road, it is safe to say that it knocks on the steering rack bushing. Replacement of the bushing is definitely required. Before the repair procedure, you should stock up on the necessary components and tools, and also study the corresponding video in detail. The repair kit will help you to carry out repairs in case of 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 sleeve, 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 oil seals.
Basic repair kit Renault Megan 2 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 required to replace the steering rack bushing. For repairs, a small gas wrench is used, a larger one will not crawl through. To save money, it is worthwhile to groove the steering rack bush yourself. To do this, use your own or existing drawing with applied dimensions.
Subject to the technology, if the replacement of the bushing was correct, the knocking will not be observed. If there are doubts, you should record the main points that were shown in the video instructions.
With severe wear of parts, the repair kit will not come in handy, since you will have to change the entire unit as a whole. Auto concern Renault advises motorists to use only the original repair kit. This ensures that all consumables will 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 the 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, it is necessary to use a repair kit for restoration. Replacing the bushing and the subsequent elimination of noise is not a difficult task, and it is quite within the power of a driver with an assistant.

To solve this problem, the officials suggest replacing the assembled rail, very expensive, about 21,000 rubles. for the original, 11,000 rubles. for not the original.
The problem is caused by a small plastic sleeve in the rail on the right. the rail goes inside it, the bushing breaks and backlash begins.
Because Renault did not provide for the replacement of this bushing; accordingly, it does not produce a repair kit for replacement. The ZF hub from a BMW car (I don't know which model) is ideal for the renaissance rail. The catalog number for the order is 7820 023 188, the cost is 81.61 Russian rubles. Slightly less compared to the cost of a new rail)
(in the photo you can see the rubber bands, which I bought separately, later I took them off, because they were not needed)
So, in order:
2) unscrew the steering tip nut
7) turn the steering wheel to the extreme right position. the sleeve can now be clearly seen
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 a lot of moments that are very difficult to do alone ... It is better not to remove the left wheel (some of them do it to make it easier to rotate the steering wheel) in order not to accidentally twist the loop of the steering column ring, which can lead to its breakage, I don't care I broke the train, I had to re-solder
You need to take a small gas wrench to unscrew the steering rod - a large one will not get through. get ready for the fact that you have to poke around with the installation of a new bushing in the bore 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 pointed noses (to squeeze the ears) and something like a long screwdriver (to push the sleeve inward). that's all
UPD: on the run 170,000, I still repaired the rail at the service, because smashed the bushings not only on the right, but also on the left, in the area of the electric booster
Replacing the steering rack bushing on the Renault Megane II can be done in-house. It will take about three hours to complete the work. You won't have to spend much, which can naturally be considered positive news in a difficult financial situation.
In fact, there are a number of signs that are quite telling indeed.
- When the car is moving in second or third gear on poor quality roads, the driver may hear the tapping clearly.
Usually, the problem really lies with the bushing, which is about to be replaced. But one should not exclude the option that the entire rake is out of order. In any case, before spending a significant amount, it is better to spend a few hours of free time. Suddenly it will turn out to get off with fright.
What can you not do without? Unfortunately, Renault engineers expected to replace the complete rail assembly rather than its individual parts. Therefore, you should not look for a repair kit, because it 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 one hundred rubles. You can find it in any salon or on the Internet.
It's good if you can use the pit. Otherwise, you will have to look for an overpass 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 worthwhile to put bricks under the wheels so that the machine does not drive off.
1. The front of the vehicle is lifted with a jack. If necessary, you should use insurance, which is used as a wooden substrate, so that the car does not break off and does not crush the one who is 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 the WD40 comes to the rescue. Carefully unscrew the steering wheel to the left as far as it will go.
4. Cut the clamps from the boot. At the factory, they install plastic ones, they should be replaced with metal ones.
5. The lock nut is unscrewed. After it - the turn of the tip, and then the boot itself.
6. Take an adjustable wrench and wind it under the power unit, and then under the lower suspension arm. The person below must pull the key towards himself. The one who is on top must constantly put the key in the correct position.
7. Unscrew the steering wheel to the right to the limit. The sleeve will be clearly visible.
8. You will need a long screwdriver to remove the part. To facilitate the task, the assistant should turn the steering wheel to the left and to the right.
9. When the bushing is worn out too much, when pulled out, it may simply fall apart into small pieces. It is not difficult 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, you cannot do without an assistant. He will have to twist the steering wheel from side to side to get the bushing into place. The sleeve can be greased with a special grease or with lithol. On this, such a procedure as replacing the steering rack bushing on the Renault Megane II is complete. For reliability, it is recommended to drive to the service station to make wheel alignment.
The new rail will provide complete silence in the vehicle interior. If on a difficult road there was an unpleasant sound and recoil to the steering wheel, then the new Renault Megan 2 steering rack will significantly improve the situation. How to determine if a Renault Megane 2 steering rack needs replacing? The main signs are a dull knock from the front when driving on uneven surfaces at a low vehicle speed. Also, the inability to set the toe, which occurs due to the backlash of the rail on the right. Quite a dull knock with a quick short swing of the steering wheel to the left or right in an immovable car.
You can replace the Renault Megane 2 steering rack with a ZF bushing from a BMW car, which is well suited to this car model, because a Renault bushing is not provided. In addition, a new tie rod retainer assembly may be required.
At the beginning, you should unscrew the right wheel in the direction of travel. Next, unscrew the steering tip nut, disconnect it. Then the steering wheel is unscrewed to the extreme left position, the plastic clamps of the boot boot are cut off, the tip locking nut is unscrewed, then the tip itself. The boot of the rail is removed.
With the help of an adjustable wrench, the traction is unscrewed. Further, when replacing the steering rack Renault Megane 2, the steering wheel is turned to the extreme right position. The sleeve is pry off with a screwdriver. You need to shake the steering wheel until the bushing comes out - it can break. Next, a new bushing is put in, grease is packed, the thrust is screwed on, and the thrust joint can be lubricated. Next, the boot is put in place, tightened with clamps, the steering tip is screwed to the rod and a counter nut.
The tip is screwed onto the steering knuckle, after which the wheel is installed. The work will take about two and a half hours. It does not cause any particular difficulties. But it's more convenient to work together. In addition, to avoid damaging the Renault Megane 2 steering rack, use a special spanner (Renault catalog no. Dir. 1305) and a rack mounting clip (Dir. 1306 for SMI steering rack or 1306-01 for TRW steering rack).
The first step is to remove the wheel. Next, unscrew the steering tip nut
We turn the steering wheel to the extreme left position, cut off the plastic clamps of the boot boot.
Unscrew the tip counter nut, unscrew the tip, remove the rail boot
We turn off the traction with an adjustable wrench (for this we push the key into the lower suspension arm under the engine, one person pulls down, being in the pit, the second sits in the wheel arch and adjusts the gas key after each turn
Next, we unscrew the steering wheel to the extreme right position, which will give us the opportunity to see the bushing well.
now we pick up the bushing with a long flat screwdriver, at this time the assistant should shake the steering wheel left and right until the bushing comes out.
In our case, the sleeve broke easily, so we had to take out the remains.
We put in a new sleeve, I had to tinker a little.
We pack with lithol grease.
We fasten the traction, grease the traction joint just in case.
We put the boot in place, tighten with clamps, fasten the steering tip to the rod and counter with a lock nut
We fasten the tip to the steering knuckle, then we put the wheel.
We assemble in the reverse order.
The main symptoms which indicate a tired steering rack bushing - this is: a strong dull knock in the front when passing irregularities at low speed, the presence of a backlash on the right and, as a consequence, the inability to normally set the toe-in, "fuzzy zero", that is, at a more or less high speed, the steering wheel does not return to zero position, as well as a dull knock at a quick short swing of the steering wheel to the left and to the right with the machine at a standstill. This photo report shows in detail how do it yourself replace steering rack bushings by car Renault Megane 2 .
The design of a car consists of many different technical elements. For its normal and trouble-free control, it is necessary that all of them are as serviceable as possible. The steering rack Renault Megan 2, like the rest of the controls, requires regular maintenance and technical control.
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 repairing the Megan 2 steering rack will require certain knowledge and skills, which usually only employees of a specialized car service have. Not knowing all the features of the device and maintenance, the repair of the Megan 2 rail may not be done with sufficient quality and lead to even greater damage. Professional repairs will be more reliable and will give confidence in the stable operation of the rack and pinion mechanism.
The signs of malfunction of the Renault Megan steering rack are the same as most of the racks of other cars of this class.
The first symptom is a knock on the steering wheel when driving. At first, you may not pay attention to it, but over time it intensifies and creates some discomfort.
It can also be an uneven distribution of effort on the steering wheel, or its absence at all, backlash and other signs. On rough roads, these faults are especially evident.
During operation, it is necessary to regularly monitor the technical condition of the vehicle. 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 inaccurate driving.
A knock can appear, 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 so happens that the sleeve is made of insufficiently strong material, which, due to intensive use, quickly loses its original properties. It can also be the natural wear and tear of parts.
A tight steering wheel also speaks of the cause of the breakdown and that Renault Megan needs a steering repair.Here, the reason may be incorrect operation of the steering tips, or EUR. Some parts need urgent replacement!
Before proceeding with the repair of the car rail, it is necessary to examine the vehicle for other related malfunctions. This could be a malfunction of the car's chassis, or something else. Thanks to this, it is possible to identify the presumptive cause of the breakdown and prevent future ones.
Before starting diagnostics, Renault Megan's car rail must be cleaned of old dirt and carefully inspect all parts of the mechanism. O-rings and seals are subject to mandatory replacement, the shaft is examined for integrity.
In the event of a malfunction of any part of the steering unit, it makes no sense to restore it. Most of them are produced primarily 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 early breakdown.
Often it is necessary to change the entire Renault Megan rail entirely due to its severe wear and the risk of more serious damage.
Repair of a Renault Megan 2 steering rack requires special knowledge and skills, as well as a suitable professional tool. Therefore, it is not possible to carry out the repair correctly, not only on your own, but not in any car service.
When repairing a Renault Megan 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 steering racks of cars.

It is unlikely that it will be possible to do without replacing the oil seals and seals in the process of repairing the Megan 2 rail. Whether the power steering drive is leaking, whether the tips - oil seals are out of alignment, in order to avoid additional problems, it is better to change them to new ones. They are inexpensive, deteriorate quickly enough - so your car will not get any worse from this.
In many cases, the repair that the Renault Megan 2 steering rack requires is limited to only replacing the sealing elements. This is if a malfunction is detected in time. So, getting sand or stones from the road can lead to more serious damage.
For the sake of fairness, it should be said that the complete absence of backlash in the steering mechanism is possible only in theory. In practice, however, a slight "free play" of the steering wheel is present in every car. It is important to ensure that the magnitude of this stroke does not increase over time.
To find out the reason for the appearance of backlash and eliminate it, the master will have to disassemble the rail by screws, scrupulously examining all the moving joints. Usually, the cause of the backlash is a change in the geometry of the rail parts, which has arisen as a result of their wear. Despite the fact that all parts of the steering mechanism are made of extra strong materials, there is no steel that would last forever.
Another cause of backlash can be the breakage 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) the appearance of a grinding, crackling or knocking sound when turning the steering wheel.
The design of the Megan 2 rack is such that even in the absence of one tooth on it, the car does not completely lose control: the steering wheel does not wedge, the car does not lead from side to side. Only in one of the sectors of its rotation there is a significant backlash. However, driving a car with such a serious malfunction becomes very dangerous. Therefore, it should be delivered to a car service by a tow truck.
Of course, breakage, deformation, wear of the rail, as well as damage to the tips are a reason for replacing 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 undergo wear, so that the repaired rail will not last long.
As you can see, in most cases, a failed Renault 2 steering gear can be repaired. A complete rail replacement is required only when at least 70% of its components are worn out. Then its repair becomes inexpedient from an economic point of view. On the practical side, the new part is always better than the old one, and if you see that the components of the rails have begun to slowly fail, it makes sense to fork out once and replace the entire mechanism at once. So you can be sure that you will pass the next hundred thousand kilometers without any problems.
