3	Support the rear axle crossmember (4) using a transmission jack, unscrew bolts (5) and lower the rear axle crossmember (4)	Transmission jack gotis://H_00.10_01.	*BA35.10-P-1003-01F
4	Remove wheel bolts (3) from wheel hub, position adaptation (6) to line up with the hole circle and attach to the wheel hub with all wheel bolts (3)		*451589003400
5	Position the extraction and insertion tool (7) to line up with the hole circle and fasten with bolts (8) to the adapter (6)		*451589003400
			*210589034300
6	Press rear axle shaft (1) out of the wheel hub and detach extraction and insertion tool (7) as well as adapter (6) from the wheel hub		*451589003400
			*210589034300
7	Support axle tube (9) with major assemblies lifting table or transmission jack	If both rear axle shafts (1) are removed simultaneously, the major assemblies lifting table should be used to support the axle tube (9). Major assembly platform lift gotis://A_01_07.1
8	Remove expansion clip on cover (10), remove cover (10)
9	Remove bolt of shock absorber (11) on axle tube (9)		*BA32.25-P-1001-03N
10	Lower the axle tube (9) carefully and guide rear axle shaft (1) out of the wheel hub	Ensure that the inner ball joint of the rear axle shaft (1) is not pulled apart as it will be irreparably damaged as a result. When lowering the axle tube (9) ensure that the rear spring does not fall out of its supports. Installation:  Observe the correct seat of the rear spring in the supports on the axle tube (9) and on the frame-type integral support. Insert the shock absorber (11) into the support on the axle tube (9).
11	Raise the axle tube (9) and attach to the shock absorber (11)	Installation:  Unscrew bolt on shock absorber (11) and lower the axle tube (9) until the rear axle shaft (1) can be inserted into the wheel hub. In the process ensure that the rear spring does not fall out of its supports.
12	Undo rear axle shaft (1) using impact extractor and extractor tool (12) on transmission and remove. Afterwards seal the transmission opening with plug	Collect escaping transmission oil in a suitable container. Installation:  Do not damage radial shaft sealing ring otherwise it may leak.
