Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the vehicle is cool before starting any work.

2. Tire Balancing

Tools Required: Wheel balancer, jack, jack stands.
Jack up the vehicle and remove the wheels.
Mount each wheel on the wheel balancer and spin to check for imbalances.
Add wheel weights as necessary to balance each tire.
Reinstall the balanced wheels onto the vehicle and torque lug nuts to specifications.

3. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor.
Check the tire pressure using a pressure gauge.
Inflate or deflate tires to the recommended pressure as indicated on the driver’s door jamb or owner's manual.

4. Wheel Alignment

Tools Required: Alignment rack (or a tape measure for DIY checks).
Inspect the alignment settings using an alignment rack.
Adjust the toe, camber, and caster as needed to match manufacturer specifications.

5. Suspension Inspection

Tools Required: Visual inspection tools, torque wrench.
Visually inspect all suspension components for signs of wear or damage, including bushings and shocks.
Replace any damaged components and torque to manufacturer specifications.

6. Wheel Bearing Inspection

Tools Required: Jack, jack stands, wheel bearing puller.
Lift the vehicle and remove the wheel.
Check for play in the wheel hub by rocking the wheel vertically and horizontally.
If play is detected, replace the wheel bearing following manufacturer guidelines.
