Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

Use a tire pressure gauge to measure tire pressure across all four tires.
Inflate tires to the recommended PSI as indicated on the driver's side door jamb.

3. Inspect and Replace Tires (if necessary)

Remove the wheels using a socket set.
Inspect each tire for damage or uneven wear.
If a tire is damaged or excessively worn, replace it with a new tire, ensuring it matches the specifications of the other tires.

4. Wheel Balancing

Mount the wheel on a wheel balancing machine.
Adjust the balance using wheel weights until the machine indicates it is balanced.
Reinstall the balanced wheels onto the vehicle.

5. Suspension Inspection and Repair

Inspect tie rods, ball joints, and control arms for play or damage.
Replace any worn or damaged suspension components using the following sub-steps:
- Use a socket set to remove the fasteners securing the component.
- Install the new component and tighten to manufacturer torque specifications.

6. Wheel Alignment
