Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure vehicle is parked on a level surface and secure it with wheel chocks.
• Disconnect the battery to prevent any electrical issues while working on the vehicle.

2. Tire Inspection and Adjustment

• Tools Required: Tire pressure gauge, tire inflator
• Check each tire's pressure and inflate to the manufacturer's specifications.
• Inspect tires for uneven wear; consider rotation or replacement if necessary.

3. Wheel Alignment and Balancing

• Tools Required: Wheel alignment tool, balance weights
• Take the vehicle to a professional alignment shop to perform a 4-wheel alignment.
• If required, balance the tires using a wheel balancing machine.

4. Drivetrain Inspection

• Tools Required: Jack stands, socket set
• Raise the vehicle and support it securely with jack stands.
• Inspect the driveshaft and axles for any signs of damage or wear. Replace any damaged parts if necessary.
• Check that all mounts (engine, transmission) are secure and not worn.

5. Suspension Component Check

• Tools Required: Wrenches, torque wrench
• Visually inspect suspension components such as control arms, bushings, and shocks for signs of wear or damage.
• Replace worn components and torque all bolts to manufacturer specifications.

6. Engine Performance Check (if applicable)

• Tools Required: OBD-II scanner
• If any engine codes are present, diagnose and repair the underlying issues (e.g., spark plugs, ignition coils).
• Clear error codes and test drive the vehicle to ensure the problem is resolved.
