Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to avoid electrical issues during repair.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle at the appropriate jacking points.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use a lug wrench to remove the wheel where the noise is originating.
Store lug nuts in a safe place for reinstallation.

4. Inspect and Replace Components

Struts/Shocks:
- Remove any protective covers if applicable.
- Unbolt the strut assembly from the knuckle and top mount.
- Replace the strut/shock if found faulty. Ensure to match the specifications.
- Reinstall the strut and torque the bolts to manufacturer specifications (typically around 90-100 lb-ft).
Bushings:
- Inspect control arm bushings for wear and cracks.
- Remove the control arm if bushings need replacement, using a bushing press for new installations.
- Ensure bushings are properly seated and torque to specifications.

5. Reassemble and Lower the Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to specifications (typically 100-110 lb-ft).
Reconnect the battery.
