Replacing radial shaft seal for input flange of rear axle differential

Special tools required:

  • 33 5 050
  • 33 5 070
  • 33 5 060
  • 00 5 010
  • 33 5 080
  • 33 0 150

IMPORTANT: Use only approved gearbox oils. See REAR AXLE - OPERATING FLUIDS .

Failure to comply with this instruction will result in serious damage to the rear axle final drive!

Necessary preliminary tasks:

  • Remove PROPELLER SHAFT AT FINAL DRIVE .

Remove retaining clip (1) and insert nut (2) with diaphragm seal.

Suspension

Mark position of flange nut (1) to bevel pinion (2).

Suspension

Release flange nut anticlockwise with special tools 33 5 050 and 33 5 070 by gripping the bevel pinion with special tools 33 5 060 and 33 5 070 .

Suspension

Pull out radial shaft seal with special tool 00 5 010 .

Suspension

Coat sealing lips of new radial shaft seal and sealing surface of bevel pinion with final drive oil.

Drive in radial shaft seal with special tool 33 5 080 or 33 0 150 .

Suspension

Clean bevel pinion thoroughly to remove remnants of screw locking agent.

Suspension

Check dust plate for damage, replace if necessary.

IMPORTANT: Clean flange nut thoroughly to remove remnants of grease and screw locking agent.

Pack collar insert (1) of flange nut with grease.

Apply a thin coating of grease to shaded area (2) of flange nut.

Coat at least four thread turns of flange nut with "Drei Bond adhesive type 1385".

Suspension

IMPORTANT: In order to avoid damaging the rear axle final drive, do not under any circumstances tighten down the flange nut (1) beyond the marker point of the bevel pinion (2).

Suspension

Place insert nut (2) with diaphragm seal in flange nut.

Introduce retaining clip (1).

Suspension

After installation:

  • Check OIL LEVEL IN REAR AXLE DIFFERENTIAL and correct if necessary.

Replacing rear cover gasket on rear axle final drive

IMPORTANT: In event of oil loss, always check rear differential for traces of wear and damage.

Necessary preliminary tasks:

  • Remove REAR AXLE FINAL DRIVE.

NOTE: Read and comply with REAR AXLE FINAL DRIVE: ASSIGNMENT TO MODEL SERIES.

Select rear axle final drive:

  • 188LW

Replacing rear cover gasket on rear differential (188lw)

WARNING: DANGER OF POISONING if oil is ingested/absorbed through the skin! RISK OF INJURY if oil comes into contact with eyes and skin!

IMPORTANT: In event of oil loss, always check rear differential for traces of wear and damage.

To avoid leaks from the rear differential cover, do not use a paper gasket in cars with liquid sealing compounds! To prevent the final drive oil from foaming over, make sure that no remnants of the liquid sealing compound are pressed into the rear axle final drive housing.

Necessary preliminary tasks:

  • Catch or draw off final drive oil.
  • Remove REAR AXLE FINAL DRIVE.

Release screws (1).

Unfasten screws (2).

Remove cover.

If necessary, remove remnants of liquid sealing compound with scraper.
