- If damaged, remove the strut or shock by unbolting it from the top and bottom mounts.
- Replace with new components, ensuring they are torqued to manufacturer specifications.
Check Control Arms and Ball Joints
- Inspect control arms for any cracks or deformation.
- Use a ball joint separator to remove the ball joint if it is worn.
- Replace with new ball joints and reassemble, ensuring to torque all bolts to specifications.
Replace Bushings
- Inspect control arm bushings for degradation.
- Use a bushing press or appropriate tool to replace worn bushings.
- Ensure proper alignment during reinstallation.
