Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and cool before beginning work.

2. Inspect and Adjust Tire Pressure

Sub-steps:
1. Use a tire pressure gauge to check each tire's pressure.
2. Inflate tires to the manufacturer's recommended pressure.
3. Inspect tires for uneven wear and bulges; replace if necessary.

3. Wheel Alignment and Balancing

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Have them perform a four-wheel alignment and balance the tires.

4. Examine Suspension Components

Sub-steps:
1. Lift the vehicle using a jack and secure with jack stands.
2. Inspect shock absorbers and struts for signs of leaks or damage.
3. Check bushings and control arms for wear and replace if needed.

5. Inspect Driveshaft and Axles

Sub-steps:
1. Visually inspect the driveshaft for any dents or bends.
2. Check the CV joints for wear; replace if they show signs of cracking or play.
3. Tighten any loose bolts on the driveshaft and axles to manufacturer specifications (consult service manual for torque values).

6. Final Checks and Reassembly

Sub-steps:
1. Reinstall any components removed during inspection.
2. Lower the vehicle and perform a visual check for any tools or parts left under the vehicle.
