Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather necessary tools and parts.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace CV Joints

Tools Required: Socket set, torque wrench, grease, new CV joint assembly if damaged.
Remove the wheel for access to the axle.
Inspect the CV joint boot for cracks or leakage. If damaged, proceed to replace:
1. Remove the axle nut using the socket set.
2. Detach the lower control arm from the knuckle to free the CV axle.
3. Pull the CV axle out of the transmission and replace with a new one.
4. Reassemble all removed components and ensure proper torque specifications (typically 50-70 ft-lbs for the axle nut).

3. Examine Suspension Components

Tools Required: Socket set, torque wrench, pry bar.
Inspect control arms, bushings, and mounts:
1. Look for signs of excessive wear or damage.
2. Replace any worn or damaged bushings or components.
3. Reassemble and ensure all bolts are torqued to manufacturer specifications.

4. Test Drive

Reconnect the battery terminal.
Perform a test drive to confirm the noise has been resolved.
