Removal axle shafts / replacing rubber seals (Mercedes-Benz C-Class W202)

Attention! The outer constant velocity joint (CV joint) is non-separable. Both cuffs are installed on the inner side of the shaft. After long-term operation, it is recommended to replace the cuffs.

Removal

1. Remove the axle shaft.



2. Unscrew the screw clamp, cut the clamp clamp and then replace it with a screw clamp.



3. Knock off the shaft cover with a punch.



4. Remove the cuff from the axle joint.

5. Use a rag to wipe off any grease on the hinge.



6. Using adjustable round nose pliers, spread the retaining ring and remove it.



7. Press out the axle shaft from the inner CV joint. To do this, use the appropriate punch (063) (length approximately 80 mm), as well as a split sleeve (063a).



8. The split bushing can be made independently according to the specified drawing.

10. If necessary, loosen the clamp of the outer cuff and remove it through the axle shaft. Make sure that no dirt gets into the joint. Before removing the cuff, remove the grease from its inner side and put it in the CV joint. If necessary, wash the inner CV joint in gasoline and inspect the ball races for wear. If there are signs of severe wear and dents, replace the entire joint.

11. Clean the axle shaft.

Installation

1. To replace the cuff, use the repair kit, which consists of one retaining ring, four clamps, one rubber cuff and 100 g of long-term MB grease for the hinge (on 1 hinge). On cars that have been in use for a long time, it is recommended to change both cuffs at once. Put a sleeve on the shaft splines to protect the cuff from damage during assembly, and if there is no such sleeve, wrap the splines with adhesive tape.



2. Put on the outer cuff, then the inner cuff. Then remove the auxiliary sleeve or adhesive tape.

3. Place the inner joint onto the axle shaft.

4. Clamp the axle shaft in a fixture or between the protective jaws of a vice at the collar flange.



5. Press the CV joint with a suitable punch until it stops (arrow) on the axle shaft.

6. Release the axle shaft from the clamp. Install a new retaining ring, paying attention to its correct fit in the slot.

7. Fill the joints and seals with the prescribed amount of Mercedes-Benz Fliessfett brand fluid grease (see table).



8. Lubricate the mating surfaces of the inner CV joint to the cover and rubber cuff with a sealant, such as Curil, Loctite 574 or Hylomar.

9. Put on the lid and rubber cuff.



10. Secure the seals with screw clamps on the CV joints and the axle shaft. On the axle shaft, the seals should be pulled over the flange to the CV joint. Install the axle shaft.

Attention! The clamp screws should have the same direction if possible, for which purpose the clamps should be installed turned 180°C towards each other.
