Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Replace Wheel Bearings

Lift the Vehicle: Use a jack to lift the front or rear of the vehicle and secure it on jack stands.
Remove Wheel: Using a socket set, remove the lug nuts and take off the wheel.
Inspect Wheel Bearing:
- Check for play in the wheel by grasping the tire at 12 and 6 o'clock positions.
- If movement is detected, the bearing needs replacement.
Remove Brake Components: If necessary, remove the brake caliper and rotor to access the wheel bearing.
Replace Wheel Bearing:
- Use a bearing puller to remove the old bearing.
- Install the new bearing using a press or appropriate installation tool, ensuring it is seated properly.
Reassemble Components: Reinstall the rotor, brake caliper, and wheel. Torque the lug nuts to the manufacturer’s specifications.

3. Tire Inspection and Replacement

Check Tire Condition: Inspect for any bulges, tears, or uneven wear.
Rotate Tires: If wear is uneven, consider rotating the tires to promote even wear.
Replace Tires: If the tires are worn beyond manufacturer specifications, replace them with new tires of the same size and specifications.
