Adjusting camber

Adjusting camber

The camber is adjusted by moving the spring strut transversely. For this purpose, undo the three fastening nuts
on the spring-strut mount and, to move the spring strut, remove the covering cap on the piston rod.
Adjusting caster
The caster is not adjustable on standard vehicles.
Adjusting toe
Preliminary work: Check whether the steering wheel is displaced with respect to the steering gear. To do this,
centre the steering gear as described below.
Turn wheels to the straight-ahead position.

Steering in centre position

Then readjust the front wheel alignment, if necessary, until pin -2- in driver -1- and lug on steering gear
housing -4- , line up.

Steering in centre position

No. 3 is the desired breaking point for pins in new steering gears. The (new) pin -2- is inserted into driver -1-
and its underside sits in lug -4- . This locks the steering gear in the centre position. After installation of a new
steering gear, the lower part of the pin is sheared off at desired breaking point -3- ) by turning the steering
wheel. The upper part of the pin -2- remains in the driver.

Mark for the centre steering position

If necessary, reposition the steering wheel. When doing this, seek the best position.

WARNING

A triggering of the airbag (malfunction in the airbag system) caused by improper work on airbag
components cannot be ruled out. In the case of such a malfunction, an unsuitable steering wheel holder
could cause injury or damage.

→ Use only steering wheel holders that do not project into the area of the airbag unit!

→ Observe safety regulations when working with airbag vehicles (see in Repair Group 69)!

Steering wheel holder

Clamp steering wheel in centre position with steering wheel holder -A- . Use only steering wheel holders that
do not project into the area of the airbag unit -B- . If necessary, shorten guide rod of steering wheel holder at
top -arrow- .

Adjusting toe

Release tie rod locking nut(s) -2- . When undoing or tightening tie rod locking nuts on the square part of the
tie rod -3- , with a spanner, apply counter-pressure. Next, adjust toe at the hexagonal part -1- of the tie rod(s).
Then tighten tie rod locking nuts -2- with the specified tightening torque.

Loosening and tightening the tie rod-lock nut

To loosen and tighten the tie rod-lock nut(s), use special tool (socket wrench insert) P 9730 -A- together with
a torque wrench -B- . The tightening torque for the tie rod-lock nut(s) of 50 Nm (37 ftlb.), when using a
socket wrench insert P 9730

, corresponds to a value of approx. 32.5 Nm (24 ftlb.) on the torque wrench.

Toe-difference angle
The toe-difference angle is not adjustable.
