Get Running gear -> Wheel alignment Guide for Audi RS E Tron Gt 4 Door First Generation (2021-2026)

A third-generation wheel bearing unit is used. The wheel hub and the wheel bearing form one unit which is flanged to the hub carri-

er. The wheel hub can be pressed out of the wheel bearing if necessary. A magnetised impulse ring, which works as an impulse

sender for the wheel speed sensor, is integrated in the wheel bearing seal.

Anti-roll bar

Tubular anti-roll bars with coupling rods are used. These are coupled at the lower wishbones. The anti-roll bars are mounted on the

subframe in bonded rubber bushes.

Shock absorber

Single-tube dampers (gas struts) are fitted and can be regulated in non-compression and compression stages. The regulating valve

inside (which has continuous adjustment) is activated by running gear control unit via a wire going through the piston rod. In the

neutral condition (not electrically activated), the damping force is low (“soft” characteristic).

Wheel alignment

The wheel alignment procedure corresponds to that of other Audi models. There are some differences when preparing the vehicle

for wheel alignment. The process is specified in the new Guided Function of the running gear control unit J775: “0074- Establish /

reset preconditions for vehicle alignment”.

After successful changes to the wheel position values, sensors/systems affected must be re-adapted/calibrated. Please follow the

instructions in the Workshop Manual and the wheel alignment computer.

Special preparations must be made before starting wheel alignment on vehicles with adaptive air suspension and/or four-wheel

steering. The precise vehicle level required for wheel alignment must be set and height regulation must be deactivated at this level.

The wheels on the rear axle must also be tightly locked in zero position. On the Audi e-tron GT, these functions no longer need to be

activated separately via the corresponding control units. This task is undertaken by the previously mentioned function “0074- Es-

tablish / reset preconditions for vehicle alignment”. The specified function is also used for vehicles with electronic damping control,

although in this case without the functions specific to air suspension.

Front axle

On the front axle, the toe settings for each wheel can be adjusted at the track rods.

The camber values can be aligned by moving the subframe to the side.

Rear axle

The toe setting at each wheel can be adjusted at the bolted connections for the track rods with the subframe or with the spindle of

the rear axle steering rack.

The camber values on the left and right sides can be set independently of each other. The eccentric bolts used to connect the front

lower wishbones to the subframe can be used to do this.

A new special tool (T90009) is used to set the toe.
