Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools required: Socket set, torque wrench, jack and jack stands, pry bar, and a flashlight.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Raise the Vehicle

Ensure the vehicle is stable before working underneath.

3. Inspect and Replace Components

Struts/Shocks:
- Remove the wheel to access the suspension.
- Using a socket set, remove the bolts securing the strut/shock to the assembly.
- Inspect for leaks or damage; replace if necessary.
Bushings:
- Check control arm and sway bar bushings for wear.
- If damaged, use a pry bar to remove old bushings and install new ones.
Loose Hardware:
- Tighten any loose bolts in the suspension assembly to the manufacturer's torque specifications.
- If bolts are stripped or damaged, replace them with new ones.

4. Reassemble and Lower the Vehicle

Reinstall the wheel and tighten lug nuts to the required torque.
Remove jack stands and lower the vehicle back to the ground.

5. Final Inspection

Perform a final check to ensure all components are secure and no tools are left in the work area.
