Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

Use a floor jack to lift the front or rear of the vehicle as needed.
Place jack stands under the vehicle for safety.

3. Inspect and Replace Suspension Components

Inspect Struts and Shocks:
- Remove the strut assembly if damaged.
- Replace with new struts if worn out. Torque strut mounting bolts to manufacturer specifications (typically around 50-70 ft-lbs).
Check Sway Bar Links:
- Remove any damaged sway bar links using a socket set.
- Install new sway bar links and torque to the specified value (around 30-40 ft-lbs).
Examine Control Arms:
- If control arms are damaged or bushings are worn, remove the control arms.
- Replace with new control arms, securing them with the appropriate torque specifications (often around 70-90 ft-lbs).

4. Reassemble and Lower Vehicle

Reinstall any components removed during inspection and repair.
Lower the vehicle carefully and remove jack stands.
Torque all bolts to manufacturer specifications.
