Solution

1. Preparation

Gather tools: jack, jack stands, torque wrench, tire pressure gauge, and a socket set.
Park the vehicle on a level surface and engage the parking brake.

2. Inspect and Replace Tires

Sub-steps:
1. Remove the wheel covers if applicable.
2. Use a tire pressure gauge to check and adjust tire pressures to the recommended PSI.
3. Inspect the tread for uneven wear or damage; replace any tires that are worn or damaged.
4. Rotate tires if necessary to ensure even wear.
Tools Required: Tire pressure gauge, socket set, jack, jack stands.

3. Inspect Wheel Bearings

Sub-steps:
1. Lift the vehicle using a jack and secure with jack stands.
2. Remove the wheel from the hub assembly.
3. Check the wheel bearings for any roughness or play by spinning the hub.
4. If bearings are faulty, remove and replace them with new bearings.
Tools Required: Socket set, torque wrench, bearing puller (if needed).

4. Inspect and Repair Drivetrain Components

Sub-steps:
1. Check the driveshaft for any signs of wear or damage.
2. Inspect CV joints for cracking or loss of grease; replace if necessary.
3. Tighten any loose components in the drivetrain.
Tools Required: Socket set, torque wrench.
