Solution

1. Preparation

• Gather tools and parts required.

2. Inspect and Replace Wheel Bearings

• Tools Required: Socket set, torque wrench, hammer, bearing puller.
• Remove the wheel by loosening the lug nuts and lifting the vehicle with a jack.
• Inspect the wheel bearing for any signs of grinding or excessive play.
