Use ramps or jack stands for better access to the suspension components.

2. Remove and Inspect Components

Sub-steps:
1. Remove the front or rear wheels (depending on where the noise is coming from) using a socket set.
2. Inspect the coil springs and shock absorbers for signs of wear or leaks.
3. Check the control arm bushings for cracks or deterioration.
4. Remove and inspect sway bar end links for any breakage or looseness.

3. Replace Worn Parts

Sub-steps:
1. If any components are found to be damaged (e.g., bushings, sway bar links), replace them with new parts.
2. Torque all bolts to the manufacturer's specifications using a torque wrench.
3. Reinstall the wheels and lower the vehicle back to the ground.

4. Final Inspection

Sub-steps:
1. Recheck all suspension components to ensure they are securely fastened.
2. Test the suspension by performing a bounce test again.
