Solution

1. Preparation

Gather necessary tools and parts.
Raise the vehicle using a jack and secure it with jack stands for safety.

2. Inspect and Replace Components

Suspension Struts/Shocks:
- Remove the wheel to gain access to the strut assembly.
- Inspect for leaks or physical damage.
- If damaged, remove the strut using a socket set and replace with a new unit.
- Torque the strut nuts to the manufacturer's specifications (typically around 30-40 ft-lbs).
Sway Bar Links:
- Check sway bar links for wear or play.
- If defective, remove the old links with a wrench and install new ones.
- Torque to specifications (usually around 20-30 ft-lbs).
Bushings:
- Inspect rubber bushings for cracking or deterioration.
- If worn, remove and replace with new bushings, ensuring they are seated properly.

3. Reassemble and Lower Vehicle

Reinstall the wheel and lower the vehicle.
Ensure all components are secure and properly torqued.
