To use a wheel alignment machine, follow these general steps:
-
Understand the Purpose of Wheel Alignment: Wheel alignment is a procedure performed by mechanics to ensure that a vehicle's suspension is properly aligned. This involves making adjustments to the tires and axles so that the wheels are aligned with each other and can make solid contact with the road.
-
Tools Used: Mechanics typically use an alignment machine that is connected to a computer. The machine has devices that clamp to the wheels of the vehicle. These devices, along with the computer, allow the mechanic to make precise adjustments to a series of measurements to achieve proper alignment.
-
Types of Alignments: There are three main types of alignments: front-end alignment, thrust alignment, and four-wheel alignment. The type of alignment your vehicle needs depends on its suspension. Your mechanic will be able to recommend the right alignment type for your vehicle.
- Front-end alignment: This type of alignment makes adjustments to the front axle.
- Thrust alignment: It involves aligning the rear wheels and axle to be parallel with the front axle and perpendicular to the center line of the car.
- Four-wheel alignment: This alignment is reserved for all-wheel drive vehicles or front-wheel drive vehicles with independent or adjustable rear suspensions. It ensures that all four wheels align in a rectangle, parallel to one another and perpendicular to the ground.
-
Alignment Process: The exact process may vary depending on the specific alignment machine and the technician's approach. However, here is a general outline of the process:
- The vehicle is typically raised on a hoist to allow easy access to the wheels.
- The technician attaches brackets or camera units to the wheels.
- The wheel alignment machine measures the current toe, caster, thrust, and camber angles of the wheels.
- The technician uses the alignment software to identify any inconsistencies and direct the alignment system to adjust the angles as needed.
- The technician may make adjustments to the camber, caster, and toe of each wheel to achieve the desired alignment.
- A real-time computer readout shows when the target angles are met.
- After the wheel alignment is complete, it's appropriate to ask for a printout that shows before and after images of the suspension alignment.
Remember, it's always best to consult a professional mechanic or refer to the specific instructions provided by the manufacturer of the wheel alignment machine for detailed guidance on its usage.
