Solution

1. Preparation

Tools Required: Tire pressure gauge, jack and jack stands, wheel alignment tool, basic hand tools (sockets, wrenches).
Ensure the vehicle is on a flat, level surface.
Raise the front of the vehicle using a jack and secure it with jack stands.

2. Tire Pressure Adjustment

Use the tire pressure gauge to check the pressure of all tires.
Inflate or deflate tires as necessary to match the recommended pressure specified in the owner’s manual.

3. Wheel Alignment

If the vehicle has experienced significant pulling, perform a wheel alignment.
Follow the alignment equipment instructions to adjust the camber, caster, and toe settings to the manufacturer's specifications.

4. Suspension Inspection

Inspect the suspension components for any signs of wear or damage.
- Check the tie rods for play.
- Examine the control arms and bushings for cracks or excessive wear.
Replace any damaged components as necessary.

5. Test Drive

After alignment and inspections, lower the vehicle and take it for a test drive.
Ensure the vehicle tracks straight and there is no longer a pull to the left.
