^ Assembly tool VAS 6180
Note:
^ After removing the hydraulic bonded rubber bushings, only conventional bonded rubber bushings must be installed.
^ The hydraulic bonded rubber bushings must be replaced on both sides of rear axle. A mixed installation is not allowed.
Removing
- Measure dimension - a - from the center of the wheel to the lower edge of the wheel housing.
- Make a note of the measurement. This is necessary to tighten the bolts for the rear axle to the bearing bracket.
- Install brake pedal loading device V.A.G 1869/2.
- Lift vehicle on lifting platform
- Remove wheels.
- Separate brake lines - arrow A - and remove clip.
- Remove left brake hose from bracket - 2
- Remove right brake hose from rear axle.
- Remove parking brake cable from brackets - arrow B -.
- Support rear axle with engine/transmission jack V.A.G 1383 A.
- Remove bolt - 1 - for bearing bracket on rear axle on both sides.
- Lower rear axle using engine and transmission jack V.A.G 1383 A.
- Tighten rear axle with tensioning strap T10038 over mounting from muffler system.
Vehicles with automatic headlight range control
- Removing coupling rod from Left Rear Level Control System Sensor G76 from rear axle go to Left rear level control system sensor G76 on rear axle for front wheel drive.
Continue for all vehicles
Note:
^ Place engine/transmission jack V.A.G. 1383 A with universal transmission support V.A.G. 135912 under the control arm (danger of accident from falling parts when pulling out the wheel hub and the wheel bearing).
Pressing out center of hydraulic bonded rubber bushing
- Install special tools on rear axle as shown on illustration.
- Pull a plastic bag over the special tools and control arm to pick up escaping oil when pressing out center of bonded rubber bushing.
- Press out center of bonded rubber bushing.
1 - VAS 6178
2 - VAS 6180/1
3 - VAS 6180/4 long
4 - VAS 6180/3
5 - VAS 6180/2
6 - V.A.G. 1383 A with V.A.G. 1359/2
Note:
^ The edges of separating device VAS 618012 must come in position between the collar of the bonded rubber bushing and the connection of the control arm.
^ The note "Top" on the separating device VAS 618012 must point to the control arm.
Pressing out sleeve of hydraulic bonded rubber bushing
CAUTION: Replace the separating device VAS 6180/2 with the counter-holder VAS 6180/8, otherwise the separating device will be damaged by the sleeve.
- Press out sleeve
1 - VAS 6178
2 - VAS 6180/1
3 - VAS 6180/4 long
4 - VAS 6180/5
5 - VAS 6180/8
6 - V.A.G. 1383 A with V.A.G. 1359/2
Note:
^ The note Top on the device VA S 618018 points to the control arm.
Installing
Install only conventional bonded rubber bushings.
Bonded rubber bushing is marked on face with marks - 1 -.
They must align with edge - arrow - on trailing arm - 2 -.
- Mark position of marks - 1 - on the long side of bonded rubber bushing.
- Install bonded rubber bushing and special tools on rear axle.
1 - VAS 6178
2 - VAS 6180/1
3 - VAS 6180/6
4 - VAS 6180/7
5 - Bonded rubber bushing
6 - VAS 6180/8
7 - V.A.G. 1383 A with V.A.G. 1359/2
Note:
^ The note Top on the device VA S 618018 points to the control arm.
- Before installing bonded rubber bushing, make sure that the mark - arrow A - align with the edge - arrow B - of trailing arm.
- Press in bonded rubber bushing until a gap of 0.2 mm - arrow - is available.
- Measure this gap - arrow - with a measure gauge - A -.
- Check position of bonded rubber bushing after installing.
Tighten vehicle to lifting platform
CAUTION: If the vehicle is not secured, there is a risk that it may slip off the hoist.
- Remove plugs from trailing arm - 3 - and tighten tensioning strap.
1 - Support arm of lifting platform
2 - Tightening strap T10038
- The vehicle must be tightened with the tensioning straps on left and right side.
- Grease bonded rubber bushing kidney shaped cavity with assembly paste G 052 150 A2 before installing rear axle.
Note:
^ If the rear axle is not lubricated when installed, it will be noisy when driving.
Tightening bearing bracket is only possible, when measured value - a - from the middle of wheel hub to lower edge bordering wheel housing is reached.
Otherwise the bonded rubber bushing will be distorted, resulting in reduced service life.
- Turn wheel hub until one of the holes for wheel bolts is at 12 o'clock position.
- Install wheel hub support T10149 with a wheel bolt.
- Lift wheel bearing housing using engine/transmission jack until dimension - a - is reached.
CAUTION:
^ Do not raise or lower vehicle while engine/transmission jack is under vehicle.
^ Do not leave engine and transmission lift under the vehicle longer than necessary.
- Tighten bolts from bearing bracket to rear axle with tightening torque.
Further installation in reverse order
- Bleed brake system
