Front suspension arms.
1 - upper arm of the front suspension, 2 - front suspension strut assembly, 3 - strut fork, 4 - drive shaft, 5 - front suspension anti-roll bar strut, 6 - lower arm of the front suspension, 7 - connecting element, 8 - steering knuckle assembly with hub.
Removal
1. Jack up the car, unscrew the bolts and remove the front wheel.
- Tightening torque: 90-110 Nm
2. Loosen the ball joint nut.
Note: Do not loosen the nut completely.
3. Using the special tool, disconnect the ball joint from the lower arm.
4. Remove the two bolts and disconnect the lower ball joint from the steering knuckle.
- Tightening torque: 100-120 Nm
5. Unscrew the lower fork bolt.
- Tightening torque: 100-120 Nm
6. Loosen the nut and disconnect the anti-roll bar from the lower arm of the front suspension.
- Tightening torque: 35-45 Nm
7. Remove the two bolts of the rear lower arm bushing.
- Tightening torque: 100-120 Nm
8. Loosen the bolt and disconnect the lower arm from the subframe.
- Tightening torque: 120-140 Nm
9. If necessary, remove the steering gear (see chapter "Steering").
10. If necessary, remove the anti-roll bar.
Disassembly
1. Unscrew the three nuts and remove the connecting element.
- Tightening torque: 120-140 Nm
2. Using a special tool, remove the rack mounting sleeve from the connecting element.
3. Using the special tool, remove the front lower arm bushing.
Examination
1. Check the rubber bushings for wear or deformation.
2. Check the lower control arm for bending or cracks.
3. Check the ball joint protective cover for cracks and damage.
4. Check all bolts for deformation and damage.
5. Check the ball joint pin rotation torque.
- a) If there are cracks or damage to the ball joint protective boot, replace the ball joint assembly.
- b) Rock the ball joint pin several times.
- c) Measure the torque of the ball joint pin.
- Nominal value: 0.1-0.4 Nm
- d) If the torque is less than the lower limit of the nominal value, replace the ball joint assembly.
- d) If the torque exceeds the upper limit of the rated value, the ball joint may be reused until the torque exceeds 1.5 Nm.
Assembly
1. Assembly of the lower arm of the front suspension is carried out in the reverse order of disassembly.
2. When assembling, install the front bushing as shown in the figure.
Installation
1. The installation of the lower arm of the front suspension is carried out in the reverse order of removal; the tightening torques of the bolts and nuts are indicated in the text describing the removal procedure and in the assembly drawing "Front suspension arms".
2. When installing and connecting the anti-roll bar strut, ensure that the length ("A") of the threaded part of the strut protruding from the nut corresponds to the specified value.
- Length "A": 3-5 mm
