Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure the vehicle with wheel chocks.
Disconnect the battery if working with electronic components.

2. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor
Use the tire pressure gauge to check the pressure of each tire.
Inflate or deflate the tires to match the manufacturer's recommended pressure found on the driver's side door jamb.

3. Tire Rotation (if uneven wear is found)

Tools Required: Jack, jack stands, lug wrench
Lift the vehicle with a jack and secure it with jack stands.
Remove the wheels using the lug wrench.
Rotate the tires as appropriate (e.g., front to back) to ensure even wear.
Reinstall the wheels and torque the lug nuts to the manufacturer's specifications.

4. Wheel Alignment

Tools Required: Alignment rack or alignment tools
If misalignment is detected, adjust the camber, caster, and toe angles as specified by the manufacturer.
Use an alignment machine for precision adjustments.
Make sure to lock all adjustment points after setting to specifications.

5. Suspension Component Repair (if damage is found)

Tools Required: Socket set, torque wrench, replacement parts
Replace any damaged or worn suspension components identified during the inspection.
Torque new components to manufacturer's specifications.
