| The vehicle must only be aligned using an alignment gauge released by the manufacturer. |
| It is recommended to align the front and rear axles during each vehicle alignment procedure. |
| Otherwise correct vehicle driving behaviour cannot be guaranteed! |
Note | t
| Only perform the appropriate vehicle alignment after approx. 1 000 to 2 000 km to allow the rubber-metal bearings, the coil springs and other axle components to fully settle. |
| t
| One cause of vibration in the vehicle can be a residual unbalance which is too high and/or off-centre runout of the wheels. |
| t
| During adjustment work try to approximate the nominal values. |
Caution | On vehicles with the ESP system, the steering wheel must not be offset, except when a new steering column is installed. |
| The steering wheel position is defined by stamped lines on the steering wheel as well as on the steering column. |
| Mark the opposite position of the steering wheel and shaft with a line, as long as this position is not factory-marked. |
| A skewed steering wheel must be corrected in the straightahead position by adjusting the lengths of the track rods → Chapter. |
| If the steering wheel is offset, the null balance of the steering angle sender -G85- must always be performed with the diagnostic unit -VAS- → Vehicle diagnostic tester. |
|
| If the fitting position of the rear axle and hence the running direction of the vehicle are not considered this could result in a skewed steering wheel. |
Note | t
| Before removing the steering wheel, observe the marked steering wheel position relative to the steering column. |
| t
| This position must not be changed! Otherwise the central position of the gear rack cannot be guaranteed! |
Caution | Steering columns supplied as spare parts do not have dotting marks. These steering columns must be dot marked after chassis alignment and a subsequent test drive. |
