2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure in all tires.
Inflate or deflate tires to match the recommended pressure specified in the owner's manual.

3. Perform Wheel Alignment

Set up the vehicle on an alignment rack.
Adjust camber, caster, and toe angles according to the specifications in the service manual.
Tighten all bolts to the specified torque values.

4. Inspect and Replace Suspension Components (if necessary)

Remove any damaged or worn suspension components.
- Use a socket set to remove nuts and bolts from control arms, tie rods, and bushings.
Replace with OEM or high-quality aftermarket parts.
Reassemble and torque to manufacturer specifications.

5. Brake System Inspection

Remove the wheels to access brake calipers.
Inspect calipers for proper operation and ensure they are not sticking.
Replace any faulty brake components as needed.
