Solution

1. Preparation

Tools Required: Tire pressure gauge, alignment tool, jack and jack stands, socket set, torque wrench.
Ensure the vehicle is parked on a level 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 tires to match the manufacturer-recommended pressure found in the owner's manual or on the sticker inside the driver’s door.

3. Tire Inspection and Replacement (if necessary)

Sub-steps:
1. Inspect each tire for uneven wear, bulges, or punctures.
2. If any tire shows significant wear or damage, replace it with a new tire of the same specification.
3. Ensure that all tires have the same tread depth to maintain uniform handling.

4. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Adjust the camber, caster, and toe settings to factory specifications using an alignment machine.
3. After adjustment, test tighten all suspension components to the manufacturer’s torque specifications.

5. Suspension Component Inspection and Replacement (if necessary)

Sub-steps:
1. Inspect tie rods, ball joints, and bushings for signs of wear or damage.
2. If any components are found to be worn, replace them with OEM or high-quality aftermarket parts.
3. Reassemble any disassembled parts and ensure all bolts are torqued to specifications.
