Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Adjust Tire Pressure

Tools Required: Tire pressure gauge, air compressor.
Check and adjust the tire pressure on all tires to the manufacturer's recommended PSI (found in the owner's manual or on the driver’s side door jamb).

3. Replace Worn Tires (if necessary)

Tools Required: Jack, jack stands, lug wrench.
Raise the vehicle using a jack, secure it with jack stands, and remove the wheel lug nuts with a lug wrench.
Inspect tires for uneven wear; replace any tires showing excessive wear.
Install new tires, ensuring they are oriented correctly (rotate if necessary), and tighten lug nuts to the manufacturer’s torque specification.

4. Perform Wheel Alignment

Tools Required: Wheel alignment machine.
After adjusting tire pressure and replacing tires (if needed), use a professional wheel alignment machine.
Follow the machine's instructions to adjust the camber, caster, and toe angles to the manufacturer's specifications.

5. Inspect and Repair Suspension Components

Tools Required: Socket set, torque wrench.
Inspect suspension components for wear. Replace any damaged parts such as control arms, bushings, or shocks.
Reassemble and torque all bolts to the manufacturer's specifications.
