Removal
Remove the drive shaft hex bolt.
Remove the wheel.
Fig. 4.50. Nut for fastening the connecting rod to the shock absorber strut
Unscrew the hex nut of the connecting rod with the shock absorber strut (Fig. 4.50).
Unscrew the nuts.
Remove the wheel bearing housing with the ball joint from the arm.
Pull the outer joint of the drive shaft out of the wheel hub.
Hang the drive shaft with wire from the body.
Note: The drive shaft should not hang freely, as bending will damage the inner joint.
Re-bolt the suspension joint to the control arm.
Attach the engine and gearbox stand with support to the hub with a wheel bolt.
Fig. 4.51. Threaded connection of the wheel bearing housing with the shock absorber strut
Disconnect the threaded connection of the wheel bearing housing from the shock absorber strut (Fig. 4.51).
Fig. 4.52. Installing the rectifier
Insert the straightener into the spline of the wheel bearing housing (Fig. 4.52).
Turn the ratchet 90° and remove it from the straightener.
Press the brake disc with your hand towards the shock absorber strut.
Otherwise, the shock absorber tube may become warped in the hole in the wheel bearing housing.
Remove the wheel bearing housing from the shock absorber tube in a downward direction and lower it using an engine and transmission stand until the shock absorber tube hangs freely.
Wire the wheel bearing housing to the console/subframe.
Remove the engine and transmission support from underneath the wheel bearing housing.
Remove the wiper arms.
Remove the casing of the water drainage box.
Fig. 4.53. Hexagon head bolts for upper shock absorber mount
Remove the hexagon-head bolts from the upper shock absorber mount and remove the shock absorber strut (Fig. 4.53).
Installation
Attach the engine and gearbox stand with support to the hub with a wheel bolt.
Install the shock absorber strut onto the wheel bearing housing and secure the strut with the internal star head screw and new nut.
The end of the screw with the internal star should be directed in the direction of travel.
Remove the straightener.
Fig. 4.54. Marking on the spring cushion
One of the two markings on the spring cushion must be facing the direction of travel (Fig. 4.54).
Remove the wire from the wheel bearing housing.
Carefully lift the wheel bearing housing using a gearbox stand until the shock absorber strut-to-cup connecting bolts can be tightened (Fig. 4.53).
If necessary, use a step ladder, such as a ladder, to tighten the bolts.
Tighten the upper shock absorber mount hex bolts.
Remove the support.
Tighten the threaded connection of the wheel bearing housing to the shock absorber strut (Fig. 4.51).
Unscrew the nuts.
Insert the drive shaft into the wheel hub.
Insert the wheel bearing housing with the suspension joint into the arm.
Screw the ball joint to the arm.
Note: Check the boot for damage and twisting.
Note: Install the gutter liner.
Note: Install the wiper arms.
Further installation is carried out in reverse order.
Install and tighten the wheel, tightening torque.
Removal the coil spring
Fig. 4.55. Installing the spring compression device: 1 – spring compress; 2 – torque wrench; 3 – nozzle; 4 – ratchet; 5 – nozzle; 6 – spring holder
Compress the spring using a spring compressor until the thrust ball bearing is released.
Note: First compress the spring to relieve the upper spring cup.
Fig. 4.56. Correct position of the spring in the holder
Make sure that the spring is correctly positioned in the spring holder (Fig. 4.56).
Remove the hex nut from the piston rod.
Remove the individual shock absorber strut components and spring using a spring compressor.
Installing a coil spring
Place the spring onto the lower cup using a spring compressor.
Fig. 4.57. Alignment of the end of the spring coil and the stop
The end of the spring coil must be in contact with the stop (Fig. 4.57).
Tighten a new hex nut onto the piston rod.
Release the clamp and remove it from the spring.
Install the shock absorber strut.
