Solution

1. Preparation

Gather necessary tools and park the vehicle on a level surface.
Ensure the vehicle is in "Park" mode and engage the parking brake.

2. Check and Adjust Tire Pressure

Tools Required: Tire pressure gauge
Sub-steps:
1. Remove valve stem caps from each tire.
2. Use the tire pressure gauge to measure the pressure in each tire.
3. Inflate or deflate tires to match the recommended pressure found in the owner's manual or on the driver's door jamb.

3. Tire Inspection and Replacement (if necessary)

Tools Required: Tire iron, jack, jack stands
Sub-steps:
1. Loosen lug nuts with the tire iron but do not remove them.
2. Jack up the vehicle and secure it with jack stands.
3. Remove the lug nuts and take off the affected tire.
4. Inspect the tire for uneven wear or damage; replace if necessary.
5. Reinstall the tire and tighten lug nuts to the manufacturer's torque specifications.

4. Wheel Alignment

Tools Required: Alignment machine
Sub-steps:
1. Position the vehicle on an alignment rack.
2. Adjust wheel angles according to manufacturer specifications.
3. Complete the alignment process and test drive to verify changes.

5. Tire Balancing

Tools Required: Tire balancer
Sub-steps:
1. Mount the tire on the tire balancer.
2. Spin the tire to determine where weights need to be added.
3. Attach the appropriate weights to balance the tire.
4. Reinstall the balanced tire on the vehicle.

6. Suspension Inspection and Repair (if necessary)

Tools Required: Wrench set, socket set
Sub-steps:
1. Examine all suspension components for signs of wear or damage.
2. Replace any worn or damaged parts (e.g., bushings, shocks).
3. Reassemble suspension components and ensure all bolts are torqued to specifications.
