Front Suspension Audi Q5 I

GENERAL REPAIR INFORMATION

When installing waxed components, contact surfaces must be cleaned. Contact surfaces must be free of wax and grease.

Torque specifications for unlubricated bolts and nuts are given.

Always replace self-locking nuts and bolts.

Always replace the bolts and nuts, which are tightened with an additional tightening angle.

Welding or straightening operations are not permitted on load-bearing or wheel-controlling components.

Always avoid the following actions with coil springs: Striking with a hammer, welding beads, applying color identification later.

Do not perform any welding or grinding (separating work) in coil spring or suspension strut area! Cover coil spring or suspension struts if necessary.

When loosening, removing or installing hydraulic, pneumatic or electrical line, always make a sketch or take a picture. Doing so records the original installation locations.

If the cable ties, brackets or mounting elements were removed during the repair procedure, they must be installed at their original location.

Do not let the drive axle hang down. The inner joint could be damaged if it is bent too far.

Vehicles without a drive axle must not be moved, otherwise the wheel bearing will be damaged. If vehicle does have to be moved, always note the following points

Install an outer joint in place of the drive axle.

Tighten the threaded connection between the drive axle and the wheel hub to 200 Nm.

Bonded rubber bushings can only be turned to a limited extent. Only tighten threaded connections at control arms if vehicle is in curb weight position or control position.

1. Wheel bearing, lifting to curb weight position on vehicles with coil springs, refer to «WHEEL BEARING, LIFTING TO CURB WEIGHT POSITION»(/audi/q5/i-2008-2012/remont/suspension-front/#front-suspension__wheel-bearing-lifting-to-curb-weight) .

As a running change in MY 2010, aluminum coupling rods were replaced by plastic coupling rods. It is not permitted to use different coupling rods on an axle.

If the vehicle must still have an axle alignment, every bolt and nut that must be loosened for adjustment must be tightened to the tightening specification. Tighten the bolts and nuts to the specified additional tightening angle after the alignment/adjustment is complete.

CONTACT CORROSION

Contact corrosion can occur when incorrect fasteners (bolts, nuts, washers, etc.) are used.

For this reason, only fastening elements with a special surface coating are installed.

In addition, rubber and plastic parts and adhesive are of non-conducting materials.

If there are doubts as to whether parts should be reinstalled, install new parts.

Note. Only use genuine Audi replacement parts. They have been checked and are compatible with aluminum. Accessories must be approved by Audi AG. Damage due to contract corrosion is not covered under warranty!

LONGITUDINAL MEMBER THREADS, REPAIRING

It is possible to service the threads of the weld nuts in the longitudinal member depending on certain conditions.

1. Servicing work may only be performed once per thread.
2. If servicing is necessary after this, the nuts must be replaced.
3. Have the thread repair checked by the responsible foreman or next person in charge.
4. Thread insert must be same length as thread in body.
5. Repair any damage to the underbody sealant.

DRIVE AXLE

The wheel bearing must not be under a load while the drive axle threaded connection on the wheel side is loose.

If the bearings are loaded by the vehicle's own weight the wheel bearing will be damaged. This reduces the service life of the wheel bearings. Therefore observe the following

1. Procedure for loosening drive axle to wheel hub threaded connection. Refer to «THREADED CONNECTION BETWEEN DRIVE AXLE AND WHEEL HUB, LOOSENING AND TIGHTENING»(/audi/q5/i-2008-2012/remont/suspension-front/#front-suspension__threaded-connection-between-drive-axle-and) .

Vehicles without a drive axle must not be moved, otherwise the wheel bearing will be damaged. If vehicle does have to be moved, always note the following points

Install an outer joint in place of the drive axle.

Tighten outer joint to 200 Nm.

Do not let the drive axle hang down. The inner joint could be damaged if it is bent too far.

WHEEL BEARING, LIFTING TO CURB WEIGHT POSITION

Special tools and workshop equipment required

1. Engine/transmission jack V.A.G 1383 A
2. Tensioning strap T10038
3. Wheel hub support T10149

Note. All bolts at suspension parts with bonded rubber bushings must always be tightened in curb weight position (unloaded condition).

Bonded rubber bushings can only be turned to a limited extent.

Parts with bonded rubber bushings must therefore be brought into a position that corresponds to the position in driving mode before being tightened (curb weight position).

Otherwise, the bonded rubber bushing will be stressed resulting in a shortened service life.

By raising appropriate suspension using V.A.G 1383 A and T10149, this position can be simulated on the hoist.

Before starting the work, take measurement -a-, for example, with a tape measure, from the center of the wheel to the lower edge of the wheel housing.

Scheme 1

Note. Measurement must be performed in curb weight position (unloaded condition).

Note measured value. It will be required for tightening bolts/nuts.

Remove the wheel.

Turn the wheel hub until one of the holes for the wheel bolts is on top.

Install T10149 with wheel bolt on wheel hub.

Note. Tightening of the respective bolts/nuts must only occur if dimension -a-, measured before installation between wheel hub center and lower edge of wheel house, has been attained.

Using V.A.G 1383 A, lift wheel bearing housing until dimension -a- is reached.

Scheme 2

Tighten respective bolts/nuts.

Lower wheel bearing housing.

Remove V.A.G 1383 A under vehicle.

Remove T10149.

LEVEL CONTROL SYSTEM SENSOR

General Information

Vehicles with electronically controlled damping and/or HID headlamps have standard automatic headlamp range control. Refer to [For engine(s) CAEB, CALB] General Information .

To function properly, the electronically controlled damping and automatic headlamp range control system need information about compression travel or rebound travel at the front and rear axles.

For this, the position of the left/right track control arm in relation to the body is transferred via a coupling rod to Left Front Level Control System Sensor -G78- and Right Front Level Control Sensor -G289-. These transmit electrical signals to the electronic damping control module -J250- and/or left/right high-intensity gas discharge lamp control module -J343/344-.

Left/right high-intensity gas discharge lamp control module, servicing, refer to [For engine(s) CAEB, CALB] Removal and Installation .

At the rear axle, these signals are transmitted from the left rear level control system sensor -G76- and right rear level control system sensor -G77- to the electronic damping control module and/or the left/right high-intensity gas discharge lamp control module.

These signals are required for determining vehicle level.

The headlamp range control responds automatically to changes in the vehicle level.

The vehicle level can change in the following situations

1. Trailer Mode.
2. Different load conditions; vehicle empty, vehicle partially or fully loaded.

Note. Programming the control position and checking the headlamp basic setting is always necessary in vehicles with electronically controlled damping if

1. The track control arm has been removed and reinstalled or replaced.
2. The subframe was replaced.
3. Installation work has been performed on the level control system sensor.
4. The level control system sensor has been replaced.
5. The threaded connection for coupling rod of level control system sensor was loosened at track control arm.

Headlamp basic setting, refer to [For engine(s) CAEB, CALB] Diagnosis and Testing .

If the vehicle has electronically controlled damping, then the control position must be programmed. Refer to CONTROL POSITION, PROGRAMMING USING VAS 5051B .
