If the ball joint is damaged, it can be replaced. To do this, drill out the rivets and secure the new joint with special bolts, which are supplied as spare parts. Transverse levers are also supplied as spare parts, complete with ball joint and rubber bushings.
Removal
Mark the position of the wheels on the hub with paint so that they can be installed in the same place during assembly. Loosen the wheel nuts on the lowered car. Raise the front of the car and remove the front wheels.
Unscrew nuts "2" securing the transverse arm to the subframe.
Disconnect both stabilizer bar links.
Disconnect the tie rod ball joint from the steering knuckle, see item 13.3.
Remove the inner clamp of the rubber cuff of the semi-axle propeller shaft.
Loosen the nut and pull out pin "1" of the ball joint.
Disconnect the wishbone from the steering knuckle. If you have difficulty, insert a pry bar between the wishbone and the car frame and push the wishbone down.
Caution: To avoid damage during subsequent assembly, wrap the cardan shaft seal with a cloth.
Remove the wishbone.
Installation
Install the wishbone onto the subframe. Align the holes and insert the bolts from above, tighten the nuts by hand.
Caution! Tighten the nuts when the car is on its wheels. To prevent the bolts from touching the gearbox housing, insert them only from above.
Install the cardan shaft and secure the cuff with a new clamp.
Insert the wishbone into the steering knuckle until it stops. Insert the pin "C" from the front, it should fit into the slots of the steering knuckle journal.
Caution: The bolt head must face forward in the direction of travel.
Tighten the pin nut to 80 Nm (55 Nm when installing a new pin). The pin should not turn. A - rubber cuff, B - steering knuckle, D - ball joint journal.
Insert the tie rod pin into the steering knuckle and tighten it with a nut to a torque of 25-30 Nm, lock the nut with a new cotter pin. Insert the cotter pin into the pin hole and bend the ends. If the cotter pin does not fit into the hole, tighten the threaded connection until the cotter pin enters the hole.
Tighten the stabilizer connecting rods to a torque of 50 Nm.
Install the front wheels so that the marks applied earlier match. Before installing the wheels, lubricate the centering surface on the wheel hub with a thin layer of grease. Screw on the wheel mounting nuts. Lower the car and tighten the nuts crosswise to a torque of 100 Nm.
Tighten the threaded connection of the transverse arm to the subframe. First, completely unscrew the nuts, and then tighten in four stages (hold the bolts from turning):
- Step 1: Tighten the nut with a torque wrench to 50 Nm.
- Step 2: Loosen the nuts completely.
- Step 3: Tighten the nuts to 50 Nm
- Step 4: Tighten the nuts with a hard wrench 90° (1/4 turn) in one go.
Attention! The car must be on its wheels.
