31 60 000 Removing and installing/replacing left or right output shaft

Special tools required :

31 5 110

NOTE: If the wishbone is detached from the front axle support, it will be necessary to carry out the wheel alignment procedure . See 32 00 150 KDS CHASSIS/WHEEL ALIGNMENT CHECK WITH VEHICLE LOAD UP TO DESIGN POSITION or 32 00 150 KDS CHASSIS/WHEEL ALIGNMENT CHECK WITH VEHICLE LOAD UP TO DESIGN POSITION .

Necessary preliminary tasks :

Remove FRONT WHEEL .
Remove REINFORCEMENT PLATE .
Remove ANTI-ROLL BAR LINK FROM ANTI-ROLL BAR .

IMPORTANT:

The radial shaft seal for the output shaft should be replaced every time the output shaft is removed and installed. See 31 51 015 REPLACING RADIAL SHAFT SEAL FOR OUTPUT SHAFT, LEFT or 31 51 020 REPLACING RADIAL SHAFT SEAL FOR OUTPUT SHAFT, RIGHT .

IMPORTANT: Circlip (1) in the bearing support/front differential must be replaced when fitting the output shaft!

IMPORTANT: Note on installation must be observed without fail!

Installation note :

Spur gearing of bearing (1) and output shaft (2) must be installed form-fit (tooth in tooth)!
Tighten collar bolt and compression spring by hand.
Check whether spur gearing is locked tooth in tooth by reciprocally rotating wheel hub/output shaft.
Once a form-fit has been ensured, tighten to final torque.

Renew RADIAL SHAFT SEAL IN FRONT AXLE DIFFERENTIAL , coat sealing lips with front differential oil.

Replace circlip and slide in output shaft, overcoming resistance of circlip. Output shaft must snap audibly into place.

IMPORTANT: High installation forces indicate that the gearing on the output shaft/rear axle final drive side gear are damaged/deformed!
Check gearing and replace components if damaged.

bearing support :

Press output shaft with special tool 31 5 110 out of bearing support and remove.

Installation note :
