Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Remove Wheel Assembly

Tools Required: Jack, jack stands, lug wrench
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.

3. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench
Inspect shock absorbers/struts for leaks and ensure they function properly by compressing them manually.
If damaged, remove the old shock absorber or strut by unbolting it from the top mount and lower control arm.
Install the new shock absorber or strut, ensuring to torque the bolts to the manufacturer's specifications (typically around 50-70 ft-lbs depending on the model).

4. Inspect and Replace Bushings

Tools Required: Bushing removal tool, socket set
Check suspension bushings for wear or cracking. If necessary, remove the control arm to access the bushings.
Use a bushing removal tool to replace worn bushings with new ones, ensuring they are seated correctly.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Tools Required: Torque wrench
Tighten the lug nuts to the manufacturer's specified torque (typically around 80-100 ft-lbs).
Reconnect the battery and perform a test drive to ensure the noise is resolved.
