Solution

1. Preparation

Tools Required: Tire pressure gauge, jack and jack stands, alignment tool (if performing alignment), torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is off.
If necessary, allow the vehicle to cool.

2. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to check the pressure in all four tires.
2. Inflate or deflate the tires to match the recommended pressure found in the owner's manual or on the driver's door jamb.
3. Recheck pressure after adjustments.

3. Tire Rotation and Inspection

Sub-steps:
1. Loosen the lug nuts on all four wheels using a lug wrench.
2. Jack up the vehicle and secure it with jack stands.
3. Remove the tires and inspect for uneven wear or damage.
4. Rotate the tires (if uneven wear is present) to promote even wear.
5. Reinstall the tires and torque the lug nuts to the manufacturer's specifications.

4. Wheel Alignment

Sub-steps:
1. If using an alignment tool, follow the tool’s instructions to measure the alignment angles of the front and rear wheels.
2. Adjust the camber, toe, and caster angles as required to meet manufacturer specifications.
3. If performing alignment professionally, take the vehicle to a certified alignment shop.
4. Confirm alignment adjustments are within acceptable tolerance levels.

5. Suspension Component Inspection

Sub-steps:
1. Inspect control arms, bushings, and tie rods for signs of wear or damage.
2. Replace any damaged components using a socket set and torque to specifications.
3. Recheck alignment if any suspension components were replaced.
