Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather tools and parts needed for repair.

2. Lift Vehicle

Use a jack to lift the front or rear of the vehicle, securing it with jack stands.
Ensure the vehicle is stable before starting work.

3. Inspect and Replace Suspension Components

Struts and Shocks:
- Remove the wheel for access.
- Unbolt the strut or shock from the lower control arm and top mount.
- Replace with new struts/shocks if leaking or damaged.
- Torque bolts to manufacturer specifications (typically around 30-40 ft-lbs).
Sway Bar Links:
- Check for wear; if damaged, remove by unbolting from the sway bar and lower control arm.
- Install new sway bar links and torque to manufacturer specifications (around 20-25 ft-lbs).
Control Arm Bushings:
- If bushings are worn, unbolt the control arm from the chassis and lower control arm.
- Replace bushings and reassemble, ensuring all bolts are torqued properly.

4. Reassemble and Lower Vehicle

Reattach the wheel and lower the vehicle from the jack stands.
Tighten wheel lug nuts to the manufacturer’s specification (usually 70-80 ft-lbs).
