Install in the reverse order of removal while noting the following:

-- When reusing the ball joint, clean any remaining locking compound residue off the pin threads.

-- Bring the control arm with the ball joint into the installation position.

CAUTION:

There is a risk of damage occurring in the threaded connection area on the wheel bearing housing if the installation position is incorrect.

Insert the ball joint -1- into the wheel bearing housing -2- up to the contact surface -arrows-.

-- Install the threaded connections for the components with bonded rubber bushings only until the stop, but do not tighten yet.

NOTE:

Bonded rubber bushings have a limited range of rotation. Only tighten the threaded connections for the suspension when the vehicle is in curb weight position.

-- Lift the wheel bearing in curb weight position. Refer to WHEEL BEARING IN CURB WEIGHT POSITION, LIFTING VEHICLES WITH COIL SPRING .

-- When tightening the threaded connection -1-, the control arm must be pressed toward the inside of the vehicle.
