Solution

1. Preparation

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

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Remove the front or rear wheels as necessary for better access.

3. Inspect and Replace Suspension Components

Shock Absorbers/Struts:
- Remove the bolts securing the shock absorbers/struts to the lower control arm and the upper mount.
- Replace with new shock absorbers/struts, ensuring proper torque specifications (typically 40-50 ft-lbs for top mount and 50-60 ft-lbs for lower bolts).
Sway Bar Links:
- Remove the sway bar link bolts from the sway bar and the control arm.
- Install new sway bar links, tightening to manufacturer specifications.
Control Arms/Bushings:
- If control arms or bushings are damaged, remove them by unbolting from the frame and lower control arm.
- Install new components, ensuring all bolts are torqued to specifications.

4. Reassemble and Lower the Vehicle

Reinstall the wheels and lower the vehicle from the jack stands.
Tighten the wheel lug nuts to the correct torque (typically 80-100 ft-lbs).
