Unscrew nut (2) and pull screw/bolt (3) out of front axle carrier (4)


When loosening the nut (2) the screw/bolt (3) must not be twisted. It is essential to counterhold screw/bolt (3).
Otherwise the locating lugs for the caster adjustment in the elastomer bearing (5a) will be sheared off when the repair kit is fitted.

 Installation: Screw nut (2) of screw/bolt (3) all the way on until it abuts, but do not tighten yet so that the elastomer bearing (5a) can twist when the vehicle is rocked to settle the suspension. Only tighten nut (2) in the ready-to-drive condition.
