Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor.
Check and adjust tire pressures to the manufacturer's specifications as listed on the driver’s side door jamb.
Inspect for valve leaks and replace if necessary.

3. Tire Rotation and Replacement

Tools Required: Jack, jack stands, lug wrench.
Rotate the tires according to the manufacturer's recommendations to ensure even wear. If one tire shows excessive wear, consider replacing it.
Re-torque lug nuts to the manufacturer's specifications (usually around 100 ft-lbs).

4. Wheel Alignment

Tools Required: Wheel alignment machine, alignment tools.
Set the vehicle on the alignment rack and follow the manufacturer's procedure to adjust camber, caster, and toe settings. Ensure all adjustments fall within specification ranges.
After adjustment, test drive to verify the alignment.

5. Suspension Inspection and Repair

Tools Required: Wrench set, socket set, pry bar.
Inspect control arms, bushings, tie rods, and shocks for wear or damage. Replace any damaged components.
Ensure all bolts are tightened to manufacturer specifications.
