5. Replace with a new CV joint and reassemble in reverse order.

3. Check and Replace Wheel Bearings

Tools Required: Bearing puller, torque wrench.
Sub-steps:
1. With the wheel removed, inspect the wheel bearings for play by wiggling the wheel.
2. If play is detected, remove the brake caliper and rotor.
3. Use a bearing puller to remove the old bearings from the hub.
4. Clean the bearing housing, then install new bearings and reassemble components, ensuring proper torque specifications are met.

4. Examine Suspension Components

Tools Required: Torque wrench, socket set.
Sub-steps:
