Removal and installation the drive shaft flange and radial thrust ball bearing (Mercedes-Benz S-Class W140)

Removal

1. Remove the drive shaft.

2. Remove the brake disc.

3. Remove the parking brake shoes.

4. Remove the drive shaft flange (10) (with the wheel support installed).

5. Remove the retaining ring (9).

6. Remove the radial thrust ball bearing (8) from the wheel support.

7. Remove the inner bearing race from the drive shaft flange.

Examination

Check the axial and radial runout of the flange (10) of the drive shaft. The maximum permissible value of the axial play of the flange is 0.03 mm, and the radial runout is also 0.03 mm.

Installation

Installation is carried out in the reverse order of removal.

Drive shaft flange

Removal

1. Insert the threaded bolt (010j) into the flange (10) from the outside and screw it to the bracket (010g).

2. Install the support plate (010d) onto the wheel support.

3. Install the pressure plate (010f) with the pressure bolt (010b) through the bracket and install it back onto the support plate (010d).



4. Install the hydraulic press (010h) between the thrust pad (010f) and the bracket (010g). Loosen the clamp bolt (010k) from the hydraulic press, then the bolt (010i) of the bracket until it contacts the clamp cylinder of the hydraulic press.



5. Screw in the clamp bolt (010k) of the hydraulic press (maximum torque 40 Nm) until the drive shaft flange is removed).



6. Hit the bracket (arrow) with a hammer.





7. If this is not enough, remove the bolt (010i) from the bracket.

Installation

Install the flange (10) onto the double row angular contact ball bearing (8) using the installation tool (08a)-(08c), (08e)-(08i). Make sure that the small pressure plate (08c) is correctly positioned on the bearing inner ring (arrow).
