Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Damaged Components

Inspect Shocks/Struts:
- Remove the wheel to access the suspension components.
- Inspect the shocks/struts for fluid leaks and physical damage.
- If damaged, unbolt the top and bottom mounts of the strut/shock.
- Replace with new components, ensuring to torque bolts to manufacturer specifications.
Check Bushings:
- Inspect control arm bushings for cracks or excessive wear.
- If necessary, remove the control arm by unbolting it from the frame and steering knuckle.
- Replace the bushings with new ones and reassemble.
Evaluate Alignment:
- After replacing any components, perform a wheel alignment to ensure proper handling and tire wear.

3. Final Assembly

Reattach the wheel and lower the vehicle back to the ground.
Torque lug nuts to the manufacturer’s specifications.
Recheck the suspension components to ensure everything is secure.
