Note:
^ The same special tools and workshop equipment can be used to replace subframe mounting on vehicles with front and all wheel drive.
^ The subframe does not have the usual bonded rubber bushings, but rather has hydraulic bushings.
^ The bushings can only be removed and installed with the subframe lowered.
^ Identify bushing location to subframe before removing.
Remove front or rear hydraulic bushings
- Remove wheels.
- Remove left and right coil spring.
- Only remove rear left/right underbody trim if front hydraulic mounting will be replaced.
1 - Left underbody trim
- If present, remove diagonal braces - 1 - and - 2 -.
Only with rear hydraulic bushing
- Remove stabilizer bar.
Procedure for front and rear hydraulic bushings
- Position engine/transmission jack V.A.G 1383 A with universal transmission support V.A.G 1359/2 and a corresponding wooden block at subframe or final drive (Fig. for vehicles with front wheel drive).
- Tighten band around subframe or final drive.
Note:
^ If a front hydraulic bushing is to be replaced, only loosen front subframe bolts.
^ If a rear hydraulic bushing is to be replaced, only loosen rear subframe bolts.
^ If you loosen an additional front or rear subframe bolt, a vehicle alignment will be necessary after installation.
- Loosen front or rear subframe bolts.
- Carefully lower subframe approx. 5 cm.
- Only remove subframe bolt where hydraulic mounting must be replaced.
- Mark location of hydraulic mounting - 1 - to subframe - 2 -, e.g. with a felt-tip pen (Fig. shows subframe on front wheel drive vehicle).

Note:
^ When removing hydraulic bushing with special tool wheel bearing tool V.A.G 1459 B, you must cut back.
Pull in front or rear hydraulic bushing
Front and hydraulic bushings are different. Ensure correct allocation when installing.
Hydraulic bushing must be installed in correct direction, note marking on subframe.
- Insert special tool with hydraulic bushing in subframe as shown.
Ensure correct location when inserting mount T40033/6.
1 - Nut T40034/1 or T40034/2
2 - Wheel hub support T40033/6
3 - Hydraulic mounting
4 - Press piece T40033/5
5 - Hollow piston cylinder HKZ-15
6 - Press piece E-5
7 - Special nut E-8-214
8 - Spindle T40034
9 - Subframe
- Pre-tension special tool with hydraulic bushing.
- Completely coat hydraulic bushing with installation lubricant G 294 421 A1 -thin with water at a ratio of 1:100-.
- Ensure ends of rubber beads on hydraulic bushing - 1 - align with markings - arrows B and C - on subframe - 2 -.
- - Arrow A - direction of travel
- Pull in hydraulic pump to stop by operating pump.
Note:
^ When pulling in hydraulic bushing with special tool V.A.G 1459 B you must cut back.
^ Ensure hydraulic bushing does not tilt while it is being pulled in, otherwise outer ring could be damaged!
- Raise subframe using engine/transmission jack V.A.G 1383 A.
- Install new subframe bolts and washers and tighten and (front wheel drive) or and (all wheel drive).
Only rear hydraulic bushing
- Install stabilizer bar.
Procedure for front and rear hydraulic bushings
- If present, install diagonal braces - 1 - and - 2 -.
- Install right and left underbody trim.
- Install left and right coil spring.
- Mount wheel and tighten. This information is contained in AESIS; Library; Additional Information; Wheels and Tire Guide
- Perform vehicle alignment if more than 2 hydraulic bushing bolts were loosened.
Alignment must take place on a VW/Audi recommended alignment stand.
