- Remove the bolt - 1 - and remove the universal joint - 2 - from the steering gear.
- Remove the front wheels.
- Loosen nut of track rod ball joint, but do not unscrew yet.
To protect thread, screw nut on pin a few turns.
- Press off track rod ball joint from wheel bearing housing using (3287A) and now unscrew nut.
- Remove the lower noise insulation.
- Remove coupling rods from stabilizer.
- Remove the nuts - arrows -.
- Remove pendulum support from transmission, unscrew bolts - 13 - to do so.
- Remove exhaust system bracket from the subframe- arrows -.
With FWD
- Remove bolts - arrows - from heat shield.
- Remove heat shield from subframe.
Continuation for All Vehicles
- Remove the bolts - 5 - and - 6 - on the steering gear.
- Remove the stabilizer bar bolts - 7 - and - 8 -.
- Subframe, locating, refer to => [ Subframe, Securing ] Subframe, Securing.
- Disconnect the connector for the service interval extension to the oil pan.
- Place (V.A.G 1383 A) under subframe.
- Place for example a block of wood - 1 - between (V.A.G 1383 A) and subframe.
- Remove the bolts - 9 - and - 10 - and slightly lower the subframe. Pay attention the electrical wiring while doing this.
- Remove heat shield - 1 - above exhaust system.
- Remove bolts - arrows -.
- Remove cable guide from subframe - arrow -.
- Unclip all other cable mounting points on steering gear.
- Disconnect the connectors - 1 - and - 2 - from the steering gear.
- Carefully lower subframe using (V.A.G 1383 A).
- Now, lift the stabilizer bar - 1 - toward the front, over the subframe - 2 - and down, while turning the stabilizer bar slightly.
- Lift down steering gear from subframe.
- Set down steering gear as depicted in the illustration.
This prevents damage to the control module - 1 -.
Installing
Install in reverse order of removal.
- Make sure the white pressure membrane - arrow - is clean and not damaged.
- If necessary, carefully clean the pressure membrane.
• If the pressure membrane is damaged, then the steering gear must be replaced.
- Connect the connectors - 1 - and - 2 - so that they audibly click into place.
The threaded sleeve must seat in subframe hole.
• Coat seal on steering gear with lubricant, e.g. soft soap, before installing steering gear.
• After placing steering gear onto universal joint, make sure that seal on steering gear makes contact on assembly plate without kinks and opening to footwell is correctly sealed. Ingress of water and/or noises may be the result.
• Make sure sealing surfaces are clean.
Before fastening the bolts for subframe, position steering gear on subframe and fasten bolts for steering gear and stabilizer.
- Remove the lower noise insulation.
- Bolt universal joint to steering gear.
- Connect battery.
- Perform steering angle sensor (G85) basic setting with the vehicle diagnostic tester.
It is necessary to adapt the electromechanical power steering with vehicle diagnostic tester if a new steering gear was installed.
- Adapt the electromechanical power steering with vehicle diagnostic tester.
