Solution

1. Preparation

Gather tools: jack and jack stands, socket set, torque wrench, tire balancer, and OBD-II scanner.
Ensure the vehicle is on a flat surface and the engine is turned off.

2. Tire Inspection and Balancing

Inspect Tires:
- Check each tire for uneven wear or bulges.
- Measure tire pressure and adjust to recommended levels.
Balance Tires:
- Remove the wheel and tire assembly from each corner.
- Use a tire balancer to check for imbalance; add weights as necessary.
- Reinstall wheels and torque lug nuts to manufacturer's specifications (typically around 80-100 ft-lbs, check the vehicle manual).

3. Drive Shaft and Suspension Inspection

Inspect Driveshaft:
- Visually inspect for dents, bends, or any signs of wear on the U-joints.
- Rotate the driveshaft to check for any binding or irregular movement.
Check Suspension:
- With the vehicle lifted, inspect control arms, bushings, and shock absorbers for any play or damage.
- Replace any worn or damaged components using appropriate tools and methods.

4. Differential Fluid Check

Check Fluid Level:
- Locate the differential fill plug; remove it to check the fluid level.
- If low, drain and replace with the manufacturer's recommended fluid (typically 75W-90 gear oil).
- Reinstall the fill plug and ensure it is tightened.
