Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Raise the vehicle using a jack and support it securely with jack stands.

2. Inspect and Replace Suspension Components

Inspect Shocks/Struts:
- Remove the wheel to access the suspension.
- Check for signs of leaking fluid from shocks/struts.
- If damaged, use a socket set to remove the mounting bolts and replace with new shocks/struts.
- Torque the bolts to the manufacturer’s specifications.
Examine Sway Bar Links:
- Locate the sway bar links and check for play or wear.
- Remove any damaged sway bar links using a wrench.
- Install new sway bar links, ensuring they are tightened to the proper torque.
Control Arm and Bushing Replacement:
- Inspect control arms for damage and bushings for wear.
- If replacement is necessary, remove the control arm bolts, then replace with new control arms and bushings.
- Torque all bolts to specifications.

3. Reassembly

Reinstall the wheel and lower the vehicle.
Tighten lug nuts to the manufacturer's specifications.
