Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal if working on electrical components.

2. Inspect and Adjust Tire Pressure

Sub-steps:
1. Use a tire pressure gauge to check the pressure of each tire.
2. Inflate or deflate tires to match the recommended pressure found on the driver’s door jamb sticker.

3. Balance the Wheels

Sub-steps:
1. Remove the wheel and tire assembly from the vehicle using a jack and jack stands.
2. Mount the wheel on the tire balancing machine.
3. Follow the machine's instructions to add weights to balance the wheel.
4. Reinstall the balanced wheel on the vehicle, tightening lug nuts to the manufacturer’s torque specifications (typically 80-100 ft-lbs).

4. Inspect and Replace Suspension Components

Sub-steps:
1. Visually inspect suspension components for cracks, leaks, or excessive wear.
2. Replace any worn bushings, struts, or shocks according to manufacturer specifications.

5. Check and Adjust Wheel Alignment

Sub-steps:
1. Use an alignment machine to check camber, caster, and toe settings.
2. Adjust alignment settings as necessary to bring them within manufacturer specifications.

6. Inspect Drivetrain Components

Sub-steps:
1. Examine CV joints and driveshaft for any signs of damage or wear, such as torn boots or excessive play.
2. Replace any damaged components as necessary.
