Mercedes w202 — outboard bearing replacement, video instruction

We will show you how to replace the outer bearing on Mercedes w202 cars. Specifically, we have the w202 C200 CDI. To work, you will need a garage with a viewing hole or an elevator, otherwise it will be troublesome and dangerous to get under the car.

First of all, we remove the support pad and put marks on the cardan shaft (in two places), this can be done with a special marker or a small notch with a screwdriver. If you assemble it arbitrarily, not according to the marking, then you will surely get a vibration of the driveshaft.

The cardan must be removed from the side of the rear axle, for this we unscrew the three screws of the cross, they turn sour many times, so it’s better to pre-lubricate them with WD. Now you can unscrew the base plate. In most cases, you need to disassemble the exhaust pipe, the bolts on its fastening often break, so buy them in advance so that you do not run around the shops later.

Carefully remove the sleeve from the rolling joint, if it is not damaged, then it will fully work again, it will be difficult for you to quickly find a new one. After the boot is removed, put a mark on the spline connection. Next, we need a press or a large vise, with which we will remove the support pad of the gimbal, and then use them to press in a new bearing.

We install the cardan shaft according to the markings applied earlier.

Remember that replacing the outer bearing on a Mercedes w202 is not an easy task, requiring certain auto repair skills and special tools.

Replacing the outboard bearing of the driveshaft Mercedes 202

Intermediate bearing wear causes noise and vibration when the vehicle is moving. The bearing is best checked by removing the drive shaft.

Note: Replacing an intermediate bearing requires a puller and hydraulic press, as well as suitable gaskets. If you do not have such equipment, entrust this operation to a specialist.

Make marks to align the front and rear of the driveshaft. Please note that some models already have markings on the shaft. In this case, the raised mark on the front of the shaft must be between the two marks on the universal joint at the rear of the shaft.

On pre-1995 models, remove the rubber boot from the collet nut and unscrew the collet nut completely.

Separate the drive shaft into two parts.

Remove the rubber boot from the back of the axle.

Using a lug puller, remove the bearing race from the end of the shaft, noting which side the race is mounted on. Remove the front and rear bearing caps.

Set the cage aside and carefully remove the bearing with a punch. 10 Inspect all parts for wear or damage

Replace if necessary. Note that bearing caps (before June 1995 only) and rubber boot must be replaced regardless of appearance.

Inspect all parts for wear or damage. Replace if necessary. Note that the bearing caps [(up to June 1995 only) and rubber boot must be replaced regardless of their appearance.

Support the cage and carefully press the new bearing into the cage using the tube just against the outer race of the bearing. 12 Clean the driveshaft of debris and install a new rear casing (on production models before June 1995)

Clean the driveshaft of debris and install a new rear guard (on production models before June 1995).

Slide the assembly onto the shaft using another tube that rests against the inner ring of the bearing. Before pressing, make sure that the cage is correctly rotated relative to the axis.

Install the front axle guard (before June 1995 only). Install the new rubber boot, making sure that its flange fits correctly into the groove on the axle.

Apply grease to the propeller shaft splines in

Mercedes W202. Outboard bearing replacement

The outer bearing is an integral part of the driveshaft even in the Mercedes W202. Its function is to keep the gimbal suspended, dampen the vibrations transmitted by the axis, and ensure free rotation around its axis. The part is a body with a cylindrical hole. Inside there is a sleeve made of anti-friction metal. The space between the suspension and the mount is filled with grease, which reduces friction and promotes the rotation of the suspension. The outer bearing must be replaced periodically.

The bearing has a service life of about 150 thousand km.

Repair

The Mercedes bearing cannot be repaired, as its integrity is violated during the wear process. Part replacement required. The process is quite complicated. Replacement requires special equipment and tools. Before removing the gimbal, be sure to make marks on it and its elements. This will help to properly install the outboard and prevent imbalance and additional vibration.

Installation of the outer bearing in stages:

  1. Removing the gearbox mounting bolts.
  2. Disassembly of suspension mounts.
  3. Expand the fixing petals and remove the clutch cardan.
  4. Shaft and circlip disassembly.
  5. knocking out the cross
  6. Loosen the bearing nut.
  7. Fork ejection and bearing removal.
  8. Cleaning the seat of a new part.
  9. Installing a new bearing.
  10. Install the shield on the bearing and tighten the locknut.
  11. Installation of new crosses.
  12. Cardan mount.
  13. Balance.

It is necessary to carry out repair work on a Mercedes very carefully so as not to damage the cardan elements. The crosspieces are also usually changed along with the suspension, since the service life of the parts is approximately the same.

Balancing the cardan shaft is the main stage of repair work on the cardan shaft. Helps eliminate vibrations while driving. If an imbalance occurs, the steering mechanism quickly becomes unusable.

Outboard bearing failures Mercedes-Benz E-Class 240 W211/S211

In principle, there are not so many malfunctions of the external bearing, since this element is quite simple and does not have a large number of components. In addition, outboard bearings have the following characteristics:

  • resistance to high temperatures,
  • oxidation resistance,
  • high resistance
  • design reliability, etc.

So, let's go over the main disadvantages:

Wear of internal bearing components. This is accompanied by the presence of a hum, hum, crunch coming directly from the outboard. Such a malfunction occurs for various reasons, including natural aging, violation of the integrity of the bearing housing, corrosion processes, deterioration in the quality of the lubricant, etc.

Violation of the integrity of the supporting body. Such a malfunction may occur in rare cases. As a rule, serious mechanical damage occurs, for example, bearing knocks. However, especially in special vehicles and SUVs operating in difficult conditions, the bearing can be deformed due to a sharp temperature drop (when wading, etc.).

Violation of the integrity of the bearing housing. The reasons why the bearing housing becomes unusable are the same as in the previous case. The problem is serious, since the holding function of the bearing is not fully performed.

Wear of the sealing elements of the bearing. This malfunction is indicated by strong vibrations transmitted to the car body from the propeller shaft. Most often this happens due to natural aging and exposure to negative environmental factors.

Regardless of the outboard bearing failure, our experts will help you to repair or replace it.

Replacing the propeller shaft outboard bearing

In a previous post, I wrote how I changed the rear subframe pads, this procedure broke down in two days. So, on the first day, we were looking for the right pillow for a long time and decided to quickly change the suspension with the mount, especially since they were bought a long time ago (NSK suspension, Fabi mount). There are few photos, everything is simple. We removed the muffler to get to the cardan, then made marks at the junction with the second half of the cardan and on the rear elastic coupling, so that later we could put everything as it was, unscrewed two screws on the outer bearing support, and six screws on the coupling rubber (we could get three to disconnect the universal joint, and the elastic coupling had to unscrew the rubber coupling from the gearbox). We start the cardan and take it out. In general, it seemed to me that the bearing was already without half the balls.

But it turned out that the bearing is still alive, but there is no lubrication there and it does not work as easily as a new one. We hammer it with a hammer, I take out a new bearing of a smaller diameter from it. It turned out from the applicability table that I have one bracket and one bearing more than I bought. In general, I ordered a new FAG 6006RSR bearing and a Lemferder 25569 01 support, and after three days of inactivity, continued the repair, the bearing was filled with some kind of grease for them, I don’t remember the names, but I remember what the Academician recommended) put a new one with a beard and a hammer the bearing into place by striking naturally on the inner race. I lubricated the inner support with graphite and she loosely dressed the bearing

I tightened the coupling so that it would not unscrew on the road) But first they primed the mount, and then tightened it with a torque of 25 Nm. Drove, nothing beats no vibration. Everywhere they write that non-originals howl in winter, let's see how ours behave next winter. My old man, though not buzzing, but now I'm calmer.
