Remove stabilizer from rear axle carrier.

Check roller bearing on both sides for damage, replace stabilizer if necessary (slight discharge of grease OK).

Keep contact face for rubber mount on anti-friction bearing clean and free from oil and grease.

Installation Note:
Check rubber mount on both sides Replacing Both Rubber Mounts for Stabilizer Mounting, replace if necessary.

Disconnect pressure lines and seal off with seal plugs.

Remove stabilizer links on both sides from stabilizer Replacing Stabilizer Links for Stabilizer.

Remove stabilizer sideways.

Installation Note:
Pressure lines are protected against being mixed up by different thread diameters on the oscillating motor connection.





Assembly: Pressure lines to oscillating motor

Note:
Before the stabilizer is installed, the pressure lines must be aligned to the oscillating motor and secured using banjo bolts.

Installation Note:
1. Screw nuts into stabilizer, do not tighten down
2. Attach special tool 33 0 170 33 0 170 Gauge to pressure lines (the side of the special tool illustrated must point in the direction of the oscillating motor)
3. Tighten down nuts
