Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a floor jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands to ensure safety.

3. Inspect Suspension Components

Shock Absorbers/Struts:
- Check for oil leaks and physical damage.
- If damaged, remove the bolts securing the strut assembly and replace with new units. Torque bolts to manufacturer specifications.
Bushings and Joints:
- Inspect control arm bushings, ball joints, and sway bar links for wear.
- Replace any worn bushings or joints. Ensure to press out the old and press in new components using a suitable tool.

4. Tighten Loose Hardware

Go through all accessible suspension bolts and nuts.
Use a torque wrench to tighten to the manufacturer's specifications. Consult the service manual for specific torque values.

5. Alignment Check

After replacing parts or tightening hardware, perform a wheel alignment.
Use an alignment machine to ensure all angles are within manufacturer specifications.
