Solution

1. Preparation

Tools Required: Tire pressure gauge, jack and jack stands, lug wrench, alignment machine.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Adjust Tire Pressure

Sub-steps:
- Use a tire pressure gauge to check the pressure of each tire.
- Inflate any under-inflated tires to the specified PSI found in the owner’s manual.
- Replace any damaged or excessively worn tires if necessary.

3. Inspect and Replace Tires (if needed)

Sub-steps:
- Remove the wheels using a lug wrench.
- Inspect the tread and sidewalls for irregularities or damage.
- If uneven wear is detected, rotate the tires or replace them as needed.
- Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (usually around 90-120 ft-lbs).

4. Suspension Component Check

Sub-steps:
- Visually inspect control arms, tie rods, and bushings for any signs of wear or damage.
- Replace any worn suspension components as necessary, following the manufacturer's guidelines.

5. Perform Wheel Alignment

Sub-steps:
- Use an alignment machine to check the alignment angles (camber, caster, and toe).
- Adjust the alignment according to the manufacturer’s specifications.
- Test drive the vehicle to ensure the pulling issue is resolved.
