Dexel use sophisticated geometry equipment to diagnose vehicle problems

Dexel are proud to be one of a few locations in our area to be able to offer a complete four wheel geometry check and adjustment service.

The increasingly uneven surface of today’s roads due to more and more speed bumps and pot-holes can cause problems with a vehicles steering and suspension systems.

However, with our sophisticated geometry equipment we can easily diagnose and rectify these problems.

Using an advanced HD camera system, customers can watch live adjustments take place from the comfort of the reception. Also as part of the service we provide customers with a printed report showing the before and after set-up such that any adjustments made can be verified and replicated.

Using this state of the art equipment we can measure and adjust the following aspects of wheel geometry;

Dexel use sophisticated geometry equipment to correct wheel alignment

Alignment (toe in and out)

The toe measurement is the difference in the distance between the front of the tyres and the back of the tyres. Toe-in means that the fronts of the tyres are closer to each other than the rears. Toe-out is just the opposite.

Dexel use sophisticated geometry equipment to correct your caster


Caster is the forward or backward tilt of the upper ball joint relative to the lower ball joint. When viewed from the side of the vehicle, if the top of the pivot is leaning toward the rear of the car, then the caster is positive. If it is leaning toward the front, it is negative.

Dexel use sophisticated geometry equipment to correct your camber


Camber is the angle of the wheel when viewed from the front of the vehicle. If the top of the wheel is leaning out from the car, then the camber is positive, if it's leaning in, then the camber is negative.

Dexel use sophisticated geometry equipment to correct your Set Back

Set Back

Set back is the amount by which one front wheel is further back than the other. If the left wheel is further back than the right, setback is negative. If the right wheel is further back than the left, setback is positive.

Dexel use sophisticated geometry equipment to correct your Thrust Angle

Thrust Angle

Thrust angle is the direction that the rear wheels are pointing in relation to the center line of the vehicle. If the thrust line is to the right, the angle is said to be positive. If the thrust line is to the left the angle is negative.

This process is also used on high performance vehicles for track set up and as part of the accident repair process.

Currently, the complete four wheel geometry adjustment system is only available at selected branches.

To enquire whether your local branch has this facility and to arrange an appointment, please follow the Branch locator link.
