Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure wheels are off the ground for easier inspection.

3. Inspect and Replace Suspension Components

Inspect Struts/Shocks:
- Check for leaks, dents, or damage.
- If damaged, remove the strut/shock assembly by loosening the upper mounting bolts and lower bolts.
- Replace with new struts/shocks, ensuring they are torqued to manufacturer specifications (typically around 15-25 ft-lbs for upper bolts and 40-60 ft-lbs for lower bolts).
Examine Sway Bar Links:
- Check for play in the sway bar links. If worn, remove by loosening the bolts at both ends.
- Replace with new links, ensuring they are tightened to specified torque values (generally around 30-40 ft-lbs).
Inspect Bushings:
- Check all bushings for cracks or deterioration.
- Replace as necessary by removing the old bushings and installing new ones using a bushing tool.

4. Reassemble and Lower Vehicle

Reinstall any components that were removed, ensuring all fasteners are securely tightened.
Lower the vehicle and remove jack stands.

5. Final Inspection

Conduct a final inspection to ensure all components are installed correctly and securely.
Check fluid levels in the shock absorbers if applicable.
