- If damaged, remove bolts securing the control arm and replace with a new one.
- Use a torque wrench to tighten bolts to the manufacturer’s specifications.
Examine Tie Rods
- Check the inner and outer tie rods for wear.
- If worn, remove the cotter pin and nut, then replace the tie rod and reassemble.
Assess CV Joints
- Inspect CV joints for cracks or tears in the boot.

Check Wheel Bearings
- If bearings are loose, remove the hub and replace the bearings as necessary.
- Ensure proper lubrication and reassemble according to specifications.

3. Reinstall Wheel and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the nuts in a crisscross pattern to the specified torque value.
