Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Replace Tires

Sub-steps:
1. Check the tire pressure using a tire gauge; inflate to the manufacturer specifications if needed.
2. Inspect all tires for uneven wear, bulges, or punctures.
3. If any tire is damaged, replace it with a new tire of the same specifications.
Tools Required: Tire pressure gauge, jack, jack stands, lug wrench.

3. Check and Replace Wheel Bearings

Sub-steps:
1. Lift the front or rear of the vehicle using a jack and secure with jack stands.
2. Remove the wheel to access the wheel hub.
3. Spin the hub to check for roughness or grinding noises indicating a bad bearing.
4. If a bad bearing is found, remove the hub assembly and replace with a new bearing.
5. Reassemble the wheel and lower the vehicle.
Tools Required: Socket set, bearing puller, grease.

4. Inspect Drivetrain Components

Sub-steps:
1. Check the differential fluid level and condition; replace if dirty or low.
2. Inspect the CV joints and axles for any signs of wear or damage.
3. Replace any damaged components as necessary.
Tools Required: Socket set, fluid pump, differential fluid.
