Carrier, Removing and Installing

Special Tools and Equipment





- 10-222 A engine support bridge
- 10-222 A/1 bracket for engine
- 3393 Testing Mandrels

Removing





- Support engine with supporting device
- Remove hubcap, for light-alloy wheels pull off center cap (use pulling hook in vehicle tools).
- Remove wheels.
- Remove sound-deadening pan.





- Before loosening carrier, special tool 3393 must be used to check whether holes -1 and -2- line up.
- If this is not the case, an axle alignment must be performed after the carrier is installed.

Note: In order not to damage the joints of the upper contra/ arms, it is necessary to use VAG1383A (engine and transmission filter), for example, to brace against too strong rebound.





- Unscrew hex nuts -3-.
- Remove hex bolt -1- and guide link to carrier.





- Unscrew hex bolts -1-.
- Remove hex bolts -2- and lower carrier in back.

NOTE: In order not to over bend the pin-side joints of the bearing and guide links, they should be fastened to the body with a tie wire or something like it.

- Pull out the hex bolts of the guide links.
- Pull guide links out of carrier.





- Unscrew hex bolt -5-.
- Remove hex nut -2-, track control link to carrier, and remove hex bolt.
- Pull cable of ABS wheel speed sensor out of bracket on brake caliper.





- Pull track control links out of carrier.





- Unscrew hex nuts -3- and -4-.
- Remove hex bolts -5-.
- Loosen hex bolt -6- until subframe can be removed.

Installing
- Replace all bolts and nuts.





- Insert carrier and thread hex bolts -5- and -6- partially.
- Start hex bolt for suspension strut to track control link





- Guide bearing and guide links into carrier.
- Put bolts in the outside holes (arrows).
- Before tightening the carrier, it must be fixed to the body using special tool 3393.





- Holes -1- and -2- of the carrier and hole -3 of the aluminum bracket must line up on both sides.

Note: Fixing the carrier in this way is a substitute for a subsequent axle alignment only when:

- If only the carrier has been removed and reinstalled.
- Holes -1- and -2- lined up before the repair.





- Start hex bolts-1- and -2-.
- Start hex nuts -3- and -4-.
- Protect hole in body for holding special tool 3393 against corrosion.

Tightening sequence/tightening torques
Thread in body can be repaired with thread insert made of wire according to DIN 8140 (Helicoil). Thread insert must have same length as thread in body.

- Bonded rubber bushings can only be turned to a limited extent. The bolted connections on the suspension links should therefore only be tightened when the vehicle is standing on the ground.





- Turn hex bolts -2- and -5- to 110 Nm + 90°
- Tighten hex bolts -6- to 70 Nm.
- Tighten hex bolt-1-.
- Tighten hex nuts -3- and -4- to 40 Nm.
- Further tighten hex bolts for guide link 80 Nm 90°.
- Further tighten hex bolts for guide link 90 Nm 90°.

Note change in coupling and in tightening torques
- Coupling to the stabilizer: Tighten to 100 Nm and 60 Nm, respectively always use new ribbed nuts suspension strut to track control link, 90 Nm.

- Insert cable of ABS wheel speed sensor into bracket on brake caliper.
- Mount wheels.
