Audi Q5: Steering Gear, Removing and Installing
Electromechanical Steering Gear, Steering Gear, Removing and Installing
Special tools and workshop equipment required
- Torque Wrench 1331 5-50Nm -VAG1331-
- Torque Wrench 1332 40-200Nm -VAG1332-
- Torque Wrench 1332 Insert - Ring Wrench - 21mm -VAG1332/7-
- Puller - Ball Joint -T40010A-
Note
Power steering gear is completely removed and installed with tie rods.
A removable heat shield mat was installed on the steering gear at start of production. Be sure to install this mat if installing the old steering gear again.
A removable heat shield mat on the steering gear was replaced by a bonded heat shield mat as a running change. It is therefore not necessary to take the mat from the old steering gear and installing on a new steering gear.
A replacement steering gear comes with the bonded heat shield mat.
Removing
- Remove the wheels.
- Remove the nut -1- from the tie rod end joint pin -2- until it is flush with the joint pin threads. Counterhold when loosening.
Note
To protect thread, screw nut on pin a few turns.
- Remove the tie rod end from the wheel bearing housing using the Puller - Ball Joint -T40010A-. Remove the nut.
Note
Make sure that both puller lever arms are parallel to each other when using greatest force, adjust if necessary.
- Remove the noise insulation. Refer to → Body Exterior; Rep. Gr.66; Noise Insulation.
- Remove the nuts -arrows- and the stabilizer bar.
- Remove the crossbrace. Refer to → Chapter "Subframe Crossbrace, Removing and Installing".
Caution
The suspension components could be damaged.
- If the subframe mount, the steering gear or the subframe crossbrace are not installed correctly, do not rest the vehicle on its wheels.
- The vehicle must not be supported on the subframe or the subframe crossbrace (for example using a floor jack).
- Remove the bolt -arrow-.
- Remove the steering intermediate shaft -1- from the steering gear -2-.
- Release the safety mechanism and push the retainer downward to remove the connector -1- for the vehicle signals (CAN Bus and terminal 15) from the Power Steering Control Module -J500-.
- Release the safety mechanism -arrow-, push the retainer downward and disconnect the connector -2- for the voltage (terminal 30) from the Power Steering Control Module -J500-.
- Remove the bolts -1 and 2-.
- Push the steering gear slightly to the side -arrow A- and remove it downward -arrow B-.
Installing
Install in reverse order of removal. Note the following:
- Install both bolts -1- loosely at first and then tighten them.
- Install the stabilizer bar. Refer to → Chapter "Stabilizer Bar, Removing and Installing".
- Install the crossbrace. Refer to → Chapter "Subframe Crossbrace, Removing and Installing".
The "program" J 500 replace control module must be started on the Vehicle Diagnostic Tester in Guided Fault Finding if a new electromechanical steering gear is installed.
- Perform an axle alignment. Refer to → Chapter "Vehicle Alignment".
