Solution

1. Preparation

Gather all tools and parts needed for the repair.
Park the vehicle on a flat, level surface and engage the parking brake.
Use wheel chocks to prevent the vehicle from rolling.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle and secure it on jack stands.
Remove the wheels for easier access to the suspension components.

3. Inspect and Replace Components

Shock Absorbers/Struts:
- Inspect for leaks or damage.
- If damaged, remove the bolts securing the struts to the knuckle and upper mounts.
- Replace with new struts, ensuring to torque bolts to manufacturer specifications (usually around 40-50 ft-lbs).
Bushings and Sway Bar Links:
- Check for cracked or worn bushings.
- If necessary, remove the old bushings using a bushing tool and install new ones.
- For sway bar links, remove nuts and bolts. Install new sway bar links, tightening to manufacturer specifications (approximately 30 ft-lbs).

4. Reassemble

Reinstall the wheels and lower the vehicle.
Ensure all components are properly torqued to specifications.
Dispose of any old parts responsibly.
