- If worn, remove the control arm using the wrench set and replace the bushings.
- Torque the control arm bolts to the manufacturer's specifications.
Examine Ball Joints:
- Check the ball joints for play by moving the wheel up and down.
- If worn, remove the old ball joint using a ball joint separator.
- Install the new ball joint and secure it according to specifications.
Strut Inspection:
- Check struts for fluid leaks and physical damage.
- If damaged, remove the strut assembly and replace it with a new strut.
- Reassemble and torque all bolts to the specified values.
