Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Tire Pressure Adjustment

Use a digital tire pressure gauge to check the pressure of each tire.
Inflate or deflate each tire to the recommended pressure (refer to the owner's manual for specifications).

3. Tire Inspection and Replacement

Remove the wheel covers (if applicable) and inspect each tire for damage.
If tires are found to be unevenly worn or damaged, replace them.
- Using a socket set, loosen the lug nuts and remove the wheels.
- Install new tires, ensuring they are properly mounted and balanced.

4. Wheel Alignment

Use an alignment machine to adjust the wheel angles.
Follow the machine’s specifications to ensure that the camber, caster, and toe are within manufacturer specifications.
Tighten any adjustment bolts to the specified torque values from the manufacturer.

5. Suspension Inspection and Repair

Inspect struts and shocks for leaks or damage.
If damaged, replace the strut or shock absorber.
- Remove the wheel to access the strut.
- Disconnect the strut from the hub and top mount.
- Install the new strut and reconnect it, ensuring all bolts are torqued to specifications.
