Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a level surface and engage the parking brake.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle.
Secure it with jack stands for safety.

3. Inspect and Replace Shock Absorbers/Struts

Remove the wheel to access the suspension.
Disconnect the upper and lower mounting bolts of the shock absorber/strut.
Carefully remove the shock absorber/strut from its mount.
Install the new shock absorber/strut, ensuring proper alignment.
Torque bolts to manufacturer specifications (typically around 30-50 ft-lbs, verify specific values).
Reinstall the wheel and lower the vehicle.

4. Replace Sway Bar Links and Bushings

Locate and disconnect the sway bar links from the sway bar and control arm.
Remove the sway bar bushings if they are worn.
Install new sway bar links and bushings, ensuring they are securely fastened.
Torque to manufacturer specifications.

5. Inspect and Replace Control Arms if Necessary

If control arms show signs of damage, unbolt them from the frame and steering knuckle.
Install new control arms and ensure bushings are in place.
Torque all bolts to manufacturer specifications.

6. Reassemble and Lower the Vehicle
