Solution

1. Preparation

Ensure the vehicle is parked on a level surface and engage the parking brake.
Gather tools: socket set, torque wrench, jack stands.

2. Inspect and Replace Damaged Components

Lift the Vehicle
- Use a jack to raise the vehicle and place it securely on jack stands.
Check Shock Absorbers
- Inspect for signs of leakage or physical damage. If defective, replace with OEM or high-quality aftermarket shock absorbers.
- Torque bolts to manufacturer specifications (usually found in the service manual).
Examine Sway Bar Links and Bushings
- Check for any wear or damage; replace if necessary.
- Use a socket to remove the sway bar link bolts, then install new links and torque to specifications.

3. Tighten Loose Bolts

Go through all suspension-related bolts and ensure they are properly torqued to manufacturer specifications. This includes control arm bolts, shock mounts, and sway bar connections.

4. Test Drive

After replacing parts and tightening bolts, lower the vehicle and conduct a test drive over bumps to confirm the noise has been resolved.
