Remover (VW 295a), press wheel hub from bearing housing. Using a
bearing puller, remove wheel bearing inner race from hub assembly.
Using Bearing Remover (VW 433), press wheel bearing from outboard end
of bearing housing.
Installation
1) Press new bearing race onto hub. Using Bearing & Hub
Installer (VW 472/1), press new bearing into bearing housing from
outboard side. Using same adapter, press wheel hub into bearing
housing. Apply a small bead of locking compound to axle splines before

NOTE: DO NOT remove both suspension struts at same time, as this
would overload axle beam bushings.
Removal
1) With vehicle on floor, remove plastic cap which covers
upper strut retaining nuts. Remove strut retaining nuts. Slowly raise
vehicle until weight is off spring. Remove bolt which retains lower
end of strut shock absorber to axle beam mount. Raise vehicle until
strut can be removed. Place strut assembly in vise.
2) Hold piston rod. Remove strut retaining nut and related
components. See Fig. 1. Remove slotted nut (some models). Remove
spacer and coil spring. If coil spring is to be replaced, ensure paint
stripe color on replacement spring matches original spring color
stripe.
Installation
1) Install protective cap and tube onto shock absorber.
Install rubber buffer with small end downward. Install snap ring and
washer. Place spring into lower seat. Install upper retainer with
spacer sleeve.
2) Tighten slotted nut (some models) which retains piston
rod. Install upper mounting hardware. Tighten piston rod. To complete
installation, reverse removal procedure. Tighten bolts and nuts to
specification. See TORQUE SPECIFICATIONS TABLE at end of article.
SUSPENSION ASSEMBLY
CAUTION: When removing suspension assembly, add weight to rear of
vehicle to prevent tipping resulting from change in center
of gravity.
Removal
1) With vehicle on floor, disconnect upper strut mount. Raise
and support vehicle. Disconnect parking brake at bracket near axle
mount.
2) Disconnect and plug brake lines. Leave flex hose attached
to suspension. Separate brake pressure regulator spring from axle beam
(if equipped). Remove nuts which retain axle beam to body.
NOTE: DO NOT install bolts and nuts fouled with undercoating. With
waxy coating on threads, true tightening torque cannot be
measured. Clean or replace bolts and nuts.
Installation
1) If axle beam mounting has been removed, adjust mounting
pad. See Fig. 2. If pad is not correctly aligned, torsional preload of
mounting bushings will be incorrect.
2) Position rear suspension on body. Install nuts retaining
axle beam to body. Raise wheel. Guide upper end of strut into body
mount.
3) Connect parking brake cables. Connect brake lines. Lower
