Removing front 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.
1. Push (press in) peg into the wheel hub with universal drive shaft/wheel hub extractor as of model '86 NR.87-1. Insertion length: 20 mm + 5 mm
2. Unscrew plastic nuts -arrows- on front wheel housing liner.
3. Fix -upper trailing arm- with spring compressor VW 552 (vehicle in illustration with conventional suspension). This involves tensioning axle strut slightly because top ball joint can otherwise get damaged. When doing this, the -spring compressor- is pushed through the hole in the axle strut, engaged in the upper opening of the wheel well (double panel) and in the axle strut and tightened with the nut. This is only necessary if the same control arm is reinstalled.
4. Press out tie rod on wheel carrier with press-out tool T10187. - When pressing out, screw fastening nut on flush (protects the ball joint thread).
5. Release lower spring strut.
6. Remove the lower connecting rod-arrow-.
7. Raise wheel carrier with a suitable lift to the extent that connecting rod and fastening pins for spring strut at the bottom are easy to remove. Use a -lift with a rubber base- to prevent slipping.
8. Undo bolt connecting lower spring strut to axle strut -arrow-.
9. Unclip cable for wear monitor and release holder on wheel carrier.
10. Disconnect the cable on the ABS sensor.
11. Press out wheel carrier at the top with press-out tool T10187. -
12. Push the protection over the drive shaft and release the drive shaft at the transmission.
13.
1. One worker must carefully pull upper wheel carrier out and turn the steering.
2. The second worker must carefully pull out drive shaft.
Installing front 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:
^ The entire threaded parts of the axle must be tightened in vehicle position. Vehicle position means: vehicle standing on the wheels, or the wheel suspension is being raised with a universal vehicle lift. -Dimension X-, from Control value: 502 mm ± 10 mm corresponds to the vehicle position.
^ Use an intermediate layer (hard rubber)! Do not damage the brake cover plate.
^ Screws are Dacromet-coated and must not be greased.
^ Grease axle nut with a little Optimoly TA aluminum paste only at mounting-face ring.
^ Grease the toothing of the drive shaft slightly with aluminum paste Optimoly TA.
^ Drive shafts must not be left hanging from the joint stop. Tie up.
^ Use new screws and fastening nuts.
^ Make sure the bevel pinions from the ball joints are clean. Clean with a lint-free cloth as necessary. Do not use cleaning agent.
^ Use correct tightening torques and torque angle.
1. Grease toothing with a little Optimoly TA aluminum paste and insert drive shaft. When doing this, press inner joint together tightly.
2. Grease the mounting-face ring of the axle nut with a little Optimoly TA aluminum paste. Screw on the axle nuts in order to prevent the shaft from slipping out.
Note:
^ If it is not possible to push shaft in all the way, use press-out tool T10187 to pull drive shaft in.
3. Insert upper wheel carrier and tie rod, mount using fastening nuts, then tighten to the specified torque. Pay attention to inner joint of drive shaft.
4. Raise wheel carrier with a suitable lift to the extent that connecting rod and fastening pins for spring strut at the bottom are easy to push in.
5. Use a -lift with a rubber base- to prevent slipping.
6. Engage cable for wear monitor and mount holder on wheel carrier.
7. Connect the cable on the ABS sensor.
Subsequent work
1. Mount the drive shaft on the transmission and tighten to the specified tightening torque.
2. Tighten lock nut for the drive shaft to the specified tightening torque. Operate the brake whilst doing so (second fitter required).
3. Fit the wheel and tighten to the specified tightening torque.
