Solution

1. Preparation

Gather tools and parts before starting the repair.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Disconnect the battery for safety if working on electrical components.

2. Tire Inspection

Sub-steps:
1. Remove the wheel covers or hubcaps if equipped.
2. Inspect the tires for uneven wear, bulges, or foreign objects.
3. Check the tire pressure and inflate to manufacturer's specifications if low.
Tools Required: Tire pressure gauge, tire iron
Safety Warnings: Ensure the vehicle is securely supported before working on tires.

3. Wheel Bearing Inspection

Sub-steps:
1. Spin the wheel by hand to listen for grinding or roughness.
2. Grasp the wheel at the 12 and 6 o'clock positions and check for play.
3. If noise persists, remove the wheel and inspect the bearing assembly.
Tools Required: Socket set, torque wrench
Safety Warnings: Wear safety goggles to protect against debris.

4. Drivetrain Inspection

Sub-steps:
1. Inspect the CV joints for torn boots or excessive grease loss.
2. Check the differential fluid level and condition; replace if contaminated.
3. Examine the driveshaft for any signs of wear or damage.
Tools Required: Fluid pump, multimeter (if electrical inspection is needed)
Safety Warnings: Allow the vehicle to cool before inspecting components close to the engine.

5. Alignment Check

Sub-steps:
1. Visually inspect the front and rear alignment by comparing tire angles.
2. If misalignment is suspected, take the vehicle to a professional alignment shop.
Tools Required: None, but a professional service may require specialized equipment.
