Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat, stable surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the appropriate wheel to access the suspension components.

3. Inspect and Replace Components

Struts/Shocks:
- Remove the strut assembly by unscrewing the top mount bolts and the lower mounting bolts.
- Replace with new struts or shocks if they show signs of leaking fluid or damage.
- Torque the strut mounting bolts to the manufacturer's specifications (usually around 40-50 ft-lbs).
Control Arms/Bushings:
- Check the control arm bushings for wear or cracking.
- If damaged, remove the control arm by unbolting it from the chassis and the steering knuckle.
- Replace with new bushings or a new control arm as necessary.
- Torque the control arm bolts to manufacturer specifications.

4. Reassemble and Lower the Vehicle

Reinstall the wheel and tighten the lug nuts to the recommended torque.
Remove the jack stands and lower the vehicle back to the ground.
Reconnect the negative battery terminal.
