Removing and Installing Drive Shaft
Removing and installing drive shaftTools
Preliminary work
1. Release axle nut (vehicle on ground) whilst operating the brake (2 fitters required).
Remove and install wheel.
Removing rear drive shaft
Note:
^ To prevent damage to the drive shaft, rear axle support side member or transmission flange, a protective tube (shop-made) 00000 must be pushed over the drive shaft or the drive shaft must be secured.
^ During removal of the drive shaft, the wheel bearing housing remains in the vehicle and is swiveled outwards at the top side.
1. Fit protection -arrow- for drive shaft. Release inner end of drive shaft from the transmission.
2. Using universal drive shaft/wheel hub extractor as of model '86 NR.87-1 carefully press out the pin of the drive shaft until the shaft can be moved by hand.
The parking brake cable must be disengaged from the parking brake lever in the passenger compartment before the drive shaft can be removed.
^ Undo parking brake lever (do not operate until after fitting! Self-adjusting!)
^ Open cover of oddments tray in centre console.
^ Remove bottom of oddments tray in centre console.
^ Disengage the relevant parking brake cable to the side of the turnbuckle.
3. Pull protective sleeve of parking brake cable -2- from guide tube on underbody -1-.
4. Detach both upper axle struts from the outside of the wheel bearing housing.
5. Undo the holder for the brake hose/wear indicator-arrow-.
6. Release connecting rod for stabilizer at bottom-1- and spring strut -2.
7. Carefully pull wheel bearing housing outwards. Guide the parking brake cable and remove the drive shaft (assistance of second fitter required).
Installing rear drive shaft
ATTENTION: Increased risk of accidents if the wheel carrier is raised improperly!
^ Injuries and material damage are possible.
^ Do not raise the wheel suspension higher than the normal vehicle position (vehicle resting on wheels).
^ When raising the suspension, use a suitable intermediate layer (hard rubber).
^ Do not damage the brake cover plate.
Note:
^ Screws are Dacromet-coated and must not be greased.
^ Grease the thread of the axle nut with Optimoly HT.
^ Grease the toothing of the drive shaft lightly with Optimoly HT.
^ To prevent damage to the drive shaft, wheel bearing housing or transmission flange, slide a protective tube (shop-made) 00000 over the drive shaft.
^ Use new screws and lock nuts.
^ Observe correct tightening torques. After tightening, loosen the connecting rod for the stabilizer 90 degrees, and tighten again (settling behavior of the ball joint!).
^ The parking brake is self-adjusting. If the basic setting of the parking brake is correct further adjustment operations on the parking brake lever or on the turnbuckle are not necessary.
^ Always check the bellows for damage and if necessary, replace them, if continuing to use the drive shaft.
1. Pull out the wheel bearing housing carefully outwards and run in the drive shaft (2 fitters required). Screw on axle nuts. Use protection for drive shaft.
2. Fit both upper control arms on the external wheel bearing housing.
3. Slide the protective sleeve of the parking brake cable -2- on the underbody onto the guide tube -1-. Ensure it is seated correctly!
4. Engage brake cable in the turnbuckle at sides.
5. Fit lower spring strut, connecting rod for stabilizer, inner drive shaft on transmission and mount for brake hose/wear indicator.
6. Remove protection for drive shaft -Arrow-.
7. Check parking brake adjustment and adjust if necessary.
Subsequent work
Remove and install wheel.
Tighten axle nut (vehicle on ground) whilst operating the brake (2 fitters required).
Checking wheel-alignment values
Check wheel alignment values and adjust if necessary.
