Wheel alignment calibration tool

Types of Wheel Alignment Calibration Instruments

Every car has a specific set of angles between its wheels and the road that is ideal for driving stability and tire longevity. This set of angles is called wheel alignment. A wheel alignment calibration tool is used to check and adjust these angles so that the wheels are aligned with the car as intended by the manufacturer. When a car is properly aligned, the wheels point straight so the driver doesn't have to constantly steer to one side. The tires also wear evenly, and the car handles well. An aligned car is safer and more fuel efficient.

There are different types of wheel alignment calibration tools:

• Wheel alignment machines: These are the most advanced tools and are essential for any alignment shop. They use high-precision sensors and lasers to measure the angles of all four wheels. The measurements are displayed on digital screens, allowing technicians to make precise adjustments. Some machines even have cameras that can take 3D pictures of the wheel angles.
• Wheel alignment gauges: This includes castor camber gauges, which measure the camber and caster angles manually, and camber gauges that are less expensive than full alignment machines but require more skilled technicians to interpret the measurements and adjust the angles.
• Turn plates: This is a simple mechanical tool that allows the wheels to turn while measuring the alignment angles. They make it easier to assess the steering while doing alignment work.
• Alignment racks: These are specialized lifts that hold the vehicle in the correct position for precise alignment work. They often include built-in systems for measuring and adjusting angles.
• Laser alignment tools: These portable devices use lasers to project alignment lines onto the shop floor. Technicians can roll the vehicle onto the lasers to check the alignment relative to the intended angles.
