Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, tire pressure gauge.
Safety Warnings: Ensure the vehicle is on a level surface and secure it with wheel chocks before lifting.

2. Remove Wheels

Loosen lug nuts on the front or rear wheels.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheels to access suspension components.

3. Inspect and Replace Components

Shocks and Struts:
- Check for oil leaks or physical damage.
- If faulty, remove the strut assembly by unbolting it from the top mount and lower control arm.
- Replace with new struts/shocks, ensuring to torque bolts to manufacturer specifications (usually around 50-60 ft-lbs).
Control Arms and Bushings:
- Inspect for play or cracks.
- If worn, remove the control arm by loosening the bolts and replace the bushings if necessary.
Ball Joints:
- Check for excessive movement.
- Replace if found loose or damaged.

4. Alignment and Reassembly

After replacing components, reassemble by putting the wheels back on.
Tighten lug nuts in a crisscross pattern to the manufacturer's torque specification (usually around 80-100 ft-lbs).
Perform a wheel alignment using alignment tools or take it to a professional.
