We remove the lower arm in case of mechanical damage or to replace the rubber-metal hinges.
Front suspension lower arm mounting parts: 1 - self-locking nut M14x1.5 (12574811); 2 - thrust washer (2101-2904045); 3 - rubber-metal hinge (2101-2904040); 4 - thrust washer (2101-2904035); 5 - lower arm axle (2101-2904032); 6 - spring washer (10517070); 7 - adjusting washer (2101-2904225/28); 8 - nut M12x1.25 (16101511); 9 - right lever (2101-2904020-01)
To perform the work, you will need a device for pressing out and pressing in rubber-metal hinges.
Removal
1. Prepare the vehicle for operations (see "Preparing a car for maintenance and repair").
2. Remove the wheel (see "Wheel - replacement").
3. Remove the front suspension spring (see "Front suspension spring - replacement").
4. With a socket wrench by 22 mm we unscrew the two self-locking nuts of the lower arm axle and remove the thrust washers.
5. With a socket wrench by 19 mm we unscrew the two nuts securing the lever axle to the crossmember and remove the thrust washers.
6. Using a mounting blade, press the lever axis away from the crossmember and remove the lever.
Between the axle and the cross member (on axle mounting bolts) the washers required for adjusting the wheel alignment angles are located. They should not be removed from the bolts unless necessary. If the washers are removed for any reason, their location should be marked.
7. When replacing the lever, remove the ball joint from it (see "Ball joints - replacement"). When replacing rubber-metal hinges, the support does not need to be removed.
8. Install the lower arm in a vice. To press out the hinge, tighten the puller bolt onto the arm axis. The bearing part of the cup should rest against the arm. Holding the bolt from turning, tighten the puller nut and press the rubber-metal hinge into the cup.
9. Similarly, we press out the hinge from the opposite side of the lever and remove the axle.
Installation
1. Having changed the position of the puller parts, we press the rubber-metal hinge into the lever.
2. Insert the axle with thrust washers through the free hole in the lever.
3. From the side of the pressed rubber-metal hinge, install the outer thrust washer on the axle and screw in a new self-locking nut without tightening it.
4. Having changed the position of the puller parts, we press the second rubber-metal hinge into the lever.
5. Having installed the thrust shaped washer on the axle, tighten the self-locking nut.
6. Install the lower arm and other parts in the reverse order of their removal.
7. Without unloading the suspension, finally tighten the lever axle nuts and install the wheel.
8. After replacing the lever or rubber-metal hinges, it is recommended to check and, if necessary, adjust the front wheel alignment angles (see "Wheel alignment angles - adjustment").
