Solution

1. Preparation

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

2. Inspect and Replace CV Joints

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar.
Instructions:
1. Lift the front of the vehicle using a jack and secure with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the CV joints for any signs of damage or excessive play.
4. If damaged, use a pry bar to detach the CV axle from the hub.
5. Replace the CV joint or entire axle as necessary, ensuring to replace any damaged boots.
6. Reattach the CV axle to the hub and torque the nut to manufacturer specifications.

3. Wheel Bearing Inspection and Replacement (if necessary)

Tools Required: Bearing puller, socket set, torque wrench.
Instructions:
1. Spin the wheel hub by hand to check for roughness or grinding.
2. If the bearing is faulty, remove the brake caliper and rotor.
3. Use a bearing puller to extract the wheel bearing from the hub assembly.
4. Install the new bearing and ensure it is seated properly.
5. Reassemble the brake components and torque to specifications.

4. Suspension Component Check

Tools Required: Socket set, torque wrench.
Instructions:
1. Inspect struts for signs of leakage or damage.
2. Check bushings for wear or cracking; replace any that are deteriorated.
3. Re-torque any loose suspension bolts to manufacturer specifications.
