Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather tools and safety equipment (gloves, safety glasses).
Disconnect the battery if working on electrical components.

2. Tire Inspection

Sub-steps:
1. Visually inspect all tires for uneven wear or bulges.
2. Check tire pressure and inflate to manufacturer specifications if necessary.
3. Rotate tires if uneven wear is found.

3. Wheel Bearing Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Spin the wheel by hand and listen for noise or roughness.
3. If rough, remove the wheel and hub assembly for further inspection.
4. Replace the wheel bearings if they are worn.

4. Drive Shaft and Universal Joint Inspection

Sub-steps:
1. Inspect the drive shaft for any visible damage or rust.
2. Check universal joints by moving them in and out; replace if there is play or noise.
3. Reassemble and secure all components.

5. Transmission Fluid Check

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Check the fluid level and condition; it should be bright red and not burnt.
3. If fluid is low or dirty, drain and replace with the appropriate transmission fluid.
