Preliminary work: Check whether the steering wheel is displaced with respect to the steering gear. To do this, center the steering gear as described below.

Turn wheels to the straight-ahead position.

Then re-adjust the front wheel alignment, if necessary, until the pin -2-  in the driver -1-  and the lug on the steering gear housing -4-  are aligned.

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

Clamp steering wheel in center 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 the top -arrow-  .

For fast and reliable steering wheel alignment in the center position use a -steering wheel balance-  (with integrated angle measurement box) → WE1343 Steering wheel balance  .

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  9730, corresponds to a value of approx. 32.5 Nm (24 ftlb.) on the torque wrench.
