- If faulty, remove the shock absorber by loosening the upper and lower mounting bolts.
- Replace with new shock absorbers, ensuring they are properly torqued to manufacturer specifications (typically around 15-20 ft-lbs for upper bolts and 30-40 ft-lbs for lower bolts).
Inspect Control Arms and Bushings
- Check control arms for cracks or bending.
- Look at bushings for signs of wear or deterioration.
- Replace any damaged control arms or bushings as necessary.

3. Tighten Loose Components

Check All Bolts and Fasteners
- Inspect all bolts around the suspension assembly and tighten any that are loose.
