retainer bolt from backing plate. Push bearing case completely to side
of dust cover. Place adhesive tape around edge of bearing case at

retainer bolt hole to prevent damage.
CAUTION: DO NOT damage bearing case or axle shaft when grinding or
chiseling retainer ring.
3) Secure axle shaft, and grind retainer ring until retainer
ring wall thickness is 0.04-0.06" (1.0-1.5 mm) on axle shaft side and
0.08" (2.0 mm) on bearing side (FIRST CUT). See Fig. 9.
4) Change angle of grind, and remove remaining 0.08" (2.0 mm)\
of retainer ring wall on bearing side (SECOND CUT). Using a chisel,
cut retainer ring. Remove ring. DO NOT damage axle shaft.
5) Install Puller (MB990787-01) to remove bearing case from
axle shaft. Rotate nuts with equal force to remove wheel bearing.

Installation
1) Apply Multipurpose Grease (SAE J310) to oil seal, oil sea\
l

cavity and contact surfaces. Install oil seal using seal driver. Press

and new retainer ring. Clearance should be less than 0.0065" (0.165
mm). If clearance exceeds specification, install a new selective snap
ring to bring clearance to specification. See SNAP RING THICKNESS
SPECIFICATION table.
