Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, socket set, torque wrench, pry bar.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands to ensure stability.

3. Inspect and Replace Shock Absorbers/Struts

Remove the wheel to access the strut assembly.
Unbolt the strut from the knuckle and upper mount.
Inspect the strut for oil leaks or physical damage.
If damaged, replace with new shock absorbers/struts, ensuring proper torque specifications (usually around 40-60 ft-lbs for strut bolts).

4. Check and Replace Sway Bar Links and Bushings

Locate the sway bar and inspect the links for wear or damage.
If the bushings are cracked or the links are loose, remove the old links.
Install new sway bar links and bushings, tightening to manufacturer specifications.

5. Inspect Control Arms and Bushings

Visually examine control arms for cracks or bending.
Use a pry bar to check bushings for excessive play.
If bushings are worn, remove the control arm and replace bushings with new ones.
Reinstall the control arm and torque bolts according to specifications.

6. Reassemble and Lower Vehicle

Reinstall the wheels and lower the vehicle to the ground.
Torque wheel lug nuts to the manufacturer's specification (usually around 80-100 ft-lbs).
Reconnect the battery if it was disconnected.
