Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues during the repair.

2. Inspect and Replace Worn Components

Shock Absorbers:
- Remove the wheel to access the suspension.
- Inspect the shock absorber for leaks or damage.
- If damaged, unbolt the top and bottom mounting points and replace with new shocks.
Control Arms and Bushings:
- Inspect both upper and lower control arms for wear.
- Check bushings for cracks or deterioration.
- If necessary, remove the control arm bolts, replace the worn bushings, and reassemble.

3. Tightening and Lubrication

Tighten All Suspension Bolts:
- Use a torque wrench to tighten all suspension bolts to manufacturer specifications.
Lubricate Moving Parts:
- Apply grease to pivot points on control arms and sway bar links to reduce noise and friction.

4. Reassemble and Test

Reinstall the wheel and torque the lug nuts to the specified torque.
Reconnect the battery.
Lower the vehicle and perform a test drive to ensure the noise is resolved.
