Solution

1. Preparation

Gather necessary tools and parts, and ensure the vehicle is parked on a level surface.
Wear safety gear including gloves and goggles.
Disconnect the battery if working on electrical components.

2. Tire Inspection

Tools Required: Tire pressure gauge, tread depth gauge.
Check tire pressure and inflate to manufacturer specifications.
Measure tread depth on all tires; replace if significantly worn or uneven.

3. Wheel Bearing Inspection

Tools Required: Jack and jack stands, socket set.
Raise the vehicle and secure it with jack stands.
Spin each wheel by hand and listen for grinding or roughness.
If a wheel bearing is faulty, proceed to replace it:
- Remove the wheel.
- Remove brake components as necessary.
- Disconnect the hub assembly and replace the bearing.

4. Driveshaft and Differential Inspection

Tools Required: Socket set, torque wrench.
Inspect the driveshaft for any signs of damage or looseness:
- Check U-joints for play.
- Tighten any loose bolts on the driveshaft.
Check the differential fluid:
- Remove the differential cover, inspect the fluid for metal shavings or contamination.
- Replace the fluid if dirty; refill to the manufacturer's specifications.

5. Transmission Fluid Check

Tools Required: Transmission fluid dipstick, funnel.
Check the transmission fluid level using the dipstick:
- If low, add fluid to the required level.
- If fluid is dark or smells burnt, consider a complete fluid change.
