Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Inspect and Replace Damaged Components

Control Arms and Bushings
- Remove wheels using a socket set.
- Inspect control arms and bushings for cracks or excessive wear.
- If damaged, remove the control arm bolts and bushings with a socket set and replace with new parts. Torque bolts to manufacturer specifications (typically around 50-70 ft-lbs, but check service manual).
CV Joints
- Examine the CV joint boots for tears.
- If damaged, remove the axle nut using a socket and impact wrench.
- Pull the axle out of the hub and replace the CV joint or entire axle as necessary.
Wheel Bearings
- Spin the wheel to check for noise; if present, remove the wheel and brake caliper.
- Use a bearing puller to remove the old bearing from the hub and replace with a new bearing. Torque the hub nut to manufacturer specifications (typically around 150-175 ft-lbs).

3. Reassemble and Test

Reattach all components in reverse order of removal.
Reinstall the wheels and lower the vehicle.
Reconnect the battery.
Perform a test drive to ensure the noise has been resolved.
