Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Safety: Ensure the vehicle is on a flat surface and secured with wheel chocks.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Shock Absorbers/Struts

Tools Required: Jack, jack stands, socket set, torque wrench
Raise the vehicle with a jack and secure it on jack stands.
Remove the wheel to access the shock absorber/strut assembly.
Disconnect any electrical connectors, if applicable.
Unbolt the top and bottom mounts of the shock absorber/strut.
Replace with new shock absorbers/struts, tightening to manufacturer specifications.
Reinstall the wheel and lower the vehicle.

3. Replace Sway Bar Links and Bushings

Tools Required: Socket set, torque wrench
With the vehicle still elevated, locate the sway bar links.
Remove the bolts securing the sway bar links to the sway bar and control arm.
Replace the old links with new ones and tighten bolts to specified torque.
Inspect and replace sway bar bushings if they are worn or cracked.

4. Inspect and Replace Control Arms and Ball Joints (if necessary)

Tools Required: Socket set, ball joint separator, torque wrench
Check for excessive play by moving the control arm.
If wear is evident, remove the bolts securing the control arm to the chassis and steering knuckle.
Use a ball joint separator to detach the ball joint from the steering knuckle.
Install new control arms and ball joints, ensuring to torque all fasteners to specifications.
