Solution

1. Preparation

Gather tools and materials: jack, jack stands, torque wrench, tire pressure gauge, wheel balancer, alignment machine.
Ensure the vehicle is on a flat surface and parked safely.
Disconnect the battery if working on any electronic components.

2. Tire Pressure Correction

Use a tire pressure gauge to check the pressure in all four tires.
Inflate or deflate tires to the recommended pressure as stated on the door jamb or owner's manual.

3. Tire Inspection and Replacement if Necessary

Remove the wheel covers or hubcaps if applicable.
Inspect each tire for damage and wear.
- Replace any tires with significant damage or uneven wear.
Ensure that tires are mounted correctly with the proper rotation (front to back).

4. Wheel Balancing

Mount the wheel on the wheel balancer.
Spin the wheel and observe any imbalances indicated by the machine.
Add wheel weights as necessary to achieve balance, following the specifications for the wheel type.

5. Wheel Alignment

Position the vehicle on an alignment rack.
Adjust the alignment settings according to manufacturer specifications using the alignment machine.
Make sure to check and adjust camber, caster, and toe settings.

6. Suspension Inspection and Repairs

Visually inspect suspension components for signs of wear or damage.
Replace any worn components (e.g., bushings, control arms, tie rods).
Reassemble any parts removed during inspection.
