Solution

1. Preparation

Tools Required: Tire pressure gauge, alignment machine, jack and jack stands, torque wrench.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to check the pressure of each tire.
2. Inflate or deflate the tires to reach the manufacturer's recommended PSI (found in the owner's manual or door jamb).
3. Recheck tire pressure after adjustments.

3. Wheel Alignment

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheels if necessary to access alignment components.
3. Connect the alignment machine and follow the manufacturer's instructions for adjustment.
4. Adjust camber, caster, and toe settings according to factory specifications.
5. Tighten all fasteners to the specified torque values.

4. Suspension Inspection

Sub-steps:
1. Inspect all suspension components visually for signs of wear or damage.
2. Shake or wiggle each component to check for play.
3. Replace any worn or damaged components as needed.

5. Tire Rotation and Replacement

Sub-steps:
1. If uneven wear is significant, consider rotating the tires to even out wear patterns.
2. Replace any tires that are excessively worn (less than 2/32" tread depth is recommended).
3. Ensure that the new tires are installed according to the vehicle's recommended rotation pattern.
