Procedure
l  Gearbox is installed
Observe general repair instructions → Chapter.
–  Remove front left wheel.
  W00-10683
–  Loosen bolts/quick-release fasteners -1- and -2- and remove front noise insulation -A-.
–  If fitted, loosen quick-release fasteners -3- and remove rear noise insulation -B-.
  A34-0530
–  If fitted, remove noise insulation -arrows- in wheel housing (left-side).
  N37-0481
–  If fitted, remove heat shield -arrows- for drive shaft (left-side).
–  Detach drive shaft -1- from flange shaft and tie as far as possible to front, taking care not to damage surface protection.
–  Place drip tray in position.
  A34-0138
–  Remove flange shaft (left-side); to do so, secure puller -T10037- to cover for final drive -arrow-.
  A39-0421
–  Lever out flange shaft oil seal using a suitable lever.
  A34-0645
–  Lightly oil outer circumference of new oil seal.
–  Drive in new flange shaft oil seal using thrust piece -T10387- until thrust piece reaches stop; keep seal straight when installing.
  Note
t  Driving-in depth (standard): 5.5 mm beneath surface of cover
t  When carrying out a repair, the oil seal is driven in to a depth of 6.5 mm using thrust piece -T10387-, so that the new seal does not bear on the same contact surface on the used flange shaft.
–  Pack space between sealing lip and dust lip half-full with sealing grease -G 052 128 A1-.
  Note
  A39-10441
t  Inspect for visible signs of damage to polygon bearings -2- (such as cracking in outer race).
t  If the polygon bearings -2- do not run smoothly with the flange shaft removed, this does not necessarily indicate that the bearings are defective. A test for noisy bearings can only be performed with the bearings installed.
t  The polygon bearings can only be renewed together with the flange shaft.
t  Always renew circlip for flange shaft -5-.
  N39-0432
–  Clamp flange shaft in vice, using jaw protectors. Use new circlip -A- to press old circlip out of groove in flange shaft.
