Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect Tires

Sub-steps:
1. Remove hubcaps or wheel covers if necessary.
2. Visually inspect the tire tread for uneven wear, bulges, or foreign objects.
3. Use a tire pressure gauge to confirm all tires are inflated to the recommended PSI.
Tools Required: Tire pressure gauge, jack, jack stands.

3. Check Wheel Bearings

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Grasp the wheel at the top and bottom, rocking it to check for play.
3. Spin the wheel to listen for grinding or roughness indicating bad bearings.
Tools Required: Jack, jack stands, socket set.

4. Examine Drivetrain Components

Sub-steps:
1. Inspect CV joints for any cracks or grease leaks.
2. Check for damage or looseness in the driveshaft and axles.
3. If necessary, replace any faulty components.
Parts Required: CV joint kit, driveshaft, or axle assembly (if damaged).

5. Tight Turns and Engine/Transmission Mounts

Sub-steps:
1. Perform a tight turn while listening for changes in noise to identify if it’s related to the differential.
2. Inspect engine and transmission mounts for cracks or excessive wear.
3. Replace any damaged mounts.
