Removing
• Check the other bushings before replacing a faulty bonded rubber bushing.
• If cracks, oil leaks or other damage is visible, this bonded rubber bushing must be replaced too.
• To replace the rubber bonded bushing, lower the back of the subframe. It is not necessary to remove the subframe.
• Do not lower the subframe more then 4 cm (1.6 inches).
• Identify mounting location to subframe before removing the bonded rubber bushing.
- Secure the vehicle to the support arm on the hoist - arrow B - with the (T10038) over the striker pin - arrow A -.
- Place a piece of foam rubber - 1 - between the sill panel and the (T10038) and then tension the strap.
• Be careful not to scratch the sill panel.
If a vehicle is not secured, there is danger that the vehicle could slip off the lift!
- Remove the rear wheels.
- Loosen the nuts on rear exhaust system brackets but only as far as to where the thread begins.
- Place (V.A.G 1383 A) under the subframe - 1 -.
- Place a wood block - 2 - under the subframe - 1 -.
- Remove the bolts - arrows -.
- Install the spindle (3346/2) and (3301) and support arm bearing installation tool (3346/3) approximately 1.5 cm into the body on the opposite side of the bonded rubber bushing to be replaced as illustrated.
1. (3301)
2. (3346/3)
3. (3346/2)
• Turn (3346/3) on the (3346/2) until dimension - a - 4 cm (1.6 inches) is reached.
- Lower the subframe 4 cm (1.6 inches) only.
Applies to a Hydraulic Bonded Rubber Bushing
- Pry the plastic stop - 1 - upward and off the bonded rubber bushing.
Applies to All
- Pry the stop plate - 1 - off the bonded rubber bushing alternating from side to side.
- Mark the installed position of the hydraulic bonded rubber bushing on the subframe - arrows - with a felt-tip pen for installation later.
- If necessary, the support - arrow - with the "small" interior diameter must be removed from the (VAS 6178) and the support (T10205/13) for that installed.
- Place the tools on the front bonded rubber bushing as shown in the illustration.
1. Nut (T10263/5)
2. Thrust piece (T40185/5). The opening faces the rubber bonded bushing.
3. Subframe
4. Support ring (T40185/6). The conical side must face upward and the ribs must fit into the openings in the rubber bonded bushing.
5. Tube (T40033/3)
6. Support ring (T10205/4)
7. (VAS 6178)
8. (T10263/5)
9. Spindle (T10263/4). The spindle pins face downward.
• Secure (VAS 6178) while pressing out.
• Bonded rubber bushing loosens "abruptly". There is the risk of injuries by tools and bonded rubber bushing coming off!
Installing
- Pry the stop plate - 1 - near the tabs - arrows - off the bonded rubber bushing alternating from side to side before installing the bonded rubber bushing.
Conventional bonded rubber bushing installed position:
• The grooves - arrows - point in direction of travel.
Hydraulic bonded rubber bushing installed position:
• The grooves - arrows - point in direction of travel.
- Place the tools on the rear bonded rubber bushing as shown in the illustration.
1. Nut (T10263/5)
2. Thrust piece (T40185/4)
3. Subframe
4. Bonded rubber bushing or the hydraulic bonded rubber bushing
5. Thrust piece (T40185/3)
6. Support ring (T10205/4)
7. (VAS 6178)
8. (T10263/5)
9. Spindle (T10263/4). The spindle pins face downward.
- Align the bonded rubber bushing with the markings made previously and push it in until the collar comes in contact with the bushing in the subframe Without Any Gaps. If necessary, tension and press over cylinder several times. While pulling in, make sure the bonded rubber bushing does not cant, otherwise outer ring could be damaged.
• The ends of the rubber bead on the bonded rubber bushing must align with the markings - arrows - on the subframe.
• After replacing the bearing, fix any paint damage on the subframe with corrosion protection, primer and black top coat.
- Mount the stop plate on the bonded rubber bushing.
Further installation is in the reverse sequence to removal. Note the following:
- Install the exhaust system brackets.
- Install the rear wheels.
