Use a CV joint puller to detach the joint from the hub and replace with a new CV joint.
Reassemble and torque the axle nut to the manufacturer's specification.

4. Replace Wheel Bearings (if faulty)

Tools Required: Bearing puller, socket set, torque wrench.
After removing the wheel, inspect the wheel bearing for play.
If the bearing is worn, use a bearing puller to remove it from the hub assembly.
Install the new bearing, ensuring it is properly seated.
Reassemble the hub and wheel, torquing all fasteners to specification.

5. Inspect and Repair Steering Components
