Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Tire Inspection and Inflation

Tools Required: Tire pressure gauge, air compressor.
Check each tire's pressure and inflate them to the manufacturer's recommended PSI.
Inspect tire tread for uneven wear; replace tires if they exceed wear indicators.

3. Wheel Balancing

Tools Required: Wheel balancer (typically available at tire shops).
Remove the wheels from the vehicle using a socket set.
Have the wheels balanced at a professional shop to ensure they are correctly aligned.

4. Suspension Component Inspection

Tools Required: Socket set, torque wrench, pry bar.
Lift the vehicle using a jack and secure it with jack stands.
Visually inspect suspension components such as struts, bushings, and control arms for signs of wear or damage.
Replace any damaged components and torque to manufacturer specifications.

5. Drivetrain Inspection

Tools Required: Socket set, torque wrench, pry bar.
Inspect the driveshaft and CV joints for any signs of wear or damage.
Replace any worn or damaged parts, ensuring to torque all fasteners to the correct specifications.
