Solution

1. Preparation

Tools Required: Floor jack, jack stands, socket set, torque wrench, stethoscope
Raise the vehicle using a floor jack and secure it with jack stands.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Inspect Suspension Components

Remove the wheel on the affected side to gain better access.
Visually inspect the struts, shocks, control arms, and bushings for wear or damage.
Check sway bar links for signs of separation or wear.

3. Tighten or Replace Components

If any bolts or fasteners are found to be loose, tighten them to the manufacturer's specifications using a torque wrench.
If any components are damaged (e.g., bushings, links), proceed to replace them:
- Sway Bar Link Replacement:
  1. Use a socket set to remove the old sway bar link.
  2. Install the new sway bar link and tighten to specifications.
- Control Arm/Bushing Replacement:
  1. Detach the control arm from the chassis and wheel hub.
  2. Replace the bushings if worn, or the entire control arm if necessary.
  3. Reattach the control arm and tighten to specifications.

4. Reassemble and Lower Vehicle

Reinstall the wheel and lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer's specifications.
