Axle Assembly: Installation
- Check that dimension "a" (see Figure) between pinion flange and rear axle suspension carrier is 6.22±.04" (158±1 mm) and that carrier is at right angles to left side support tube. Insert suitable conical installation mandrel (111 589 00 61) on rear axle suspension carrier, raise axle and guide carrier into rubber mounts. Correctly position clamping plate and screw in bolt. Install circlip, lower jack and tighten bolt. Remove holding clamp.
- Install shock absorbers and attach cross strut with both links to carrier. Attach radius arm to chassis and reconnect brake lines. Bleed brakes. On vehicles with air suspension, attach supporting piston to radius arm and make sure set pin for locating piston is correctly mounted in radius arm. Also check seat of supporting piston in bellows. On conventional suspension models, install rear springs and compensating spring.
- Mount lever for brake hold down to frame side member. Install propeller shaft and slightly tighten intermediate bearing nuts. Check axle oil level and lower vehicle. Move vehicle back and forth several times, then tighten clamping nut on propeller shaft and intermediate bearing nuts. Attach heat shield (if equipped) and install rear brake cables and exhaust system. Install torsion bar and adjust parking brake.
- On vehicles with air suspension, place control valve lever in zero position and fill system with compressed air. Lower vehicle carefully.CAUTION: Vehicle does not have full ground clearance.
Adjust rear ride height. On vehicles with conventional suspension, make sure rear axle tracks correctly.
