6. Using extractor/pulling-in equipment (010) 140 589 03 61 00 with set bolt (010b) and thrust piece (010a), pull rear axle shaft flange (10) out of angular-contact ball bearing (8) and remove.
Installation note
Using extractor/pulling-in equipment (08a, 08b, 08c and 08e) 124 589 05 43 00 draw rear axle shaft flange (10) into two-row angular-contact ball bearing (8).
Caution:
During the pulling-in process, the thrust washer 124 589 05 43 00, part 03 (08c) must fit tightly against the bearing inner race (arrow). In the case of the two-row angular-contact ball bearing, use the thrust washer side of 45 mm dia. (smaller dia.) and in the case of the two-row angular-contact roller bearing, use the thrust washer side of 49 mm dia. (larger dia., Tmodel only).

10. Using aluminium jaws clamp rear axle shaft flange in vise. Place thrust piece (010b) 000 589 03 34 00 with large diameter on rear axle shaft flange (10).
11. Clamp puller on bearing inner race, using puller 001 589 50 33 00 or 001 589 36 33 00 and collet chuck 201 589 00 34 00 pull bearing inner race off rear axle shaft flange. 41 mm open end wrench 201 589 00 01 00.
Testing
12. Check all parts to make sure they can be reused. Check radial and lateral runout of rear axle shaft flange (nominal value 0.03 mm). Always replace two-row angular-contact ball bearing after it has been used once.
13. Install in reverse sequence.
