The correct wheel position provides well-functioning steering.
The car's operating system must meet certain requirements. One must be able to steer the car in a balanced manner, steering and swing stability must be good, and the steering must have smooth self-propulsion at all speeds. When the steering works well, the tyre wear will also be minimal. In order for the operating system to function optimally, the wheel position (geometry) must be correct.
Wheel position control is one of the car's most important service measures
With the correct wheel setting, you can make sure that the rolling direction of all the wheels of the car is in line with the car's centre line and the vehicle's travel angle is zero. On vehicles with front-wheel drive, the traction tends to turn the wheels so that they "plough". This attempts to compensate by letting the wheels "pour" a little. On vehicles with rear-wheel drive, the rolling resistance makes the wheels tend to start to lean on driving straight ahead, which can be corrected through wheel alignment adjustment. By changing the angle of the front wheels, the car will go exactly in the direction of travel without pulling on either side. At the SRC Auto Care, we have the latest wheel alignment equipment. This equipment sees any errors on the car's wheel position, which can then be adjusted.
Wheel adjustment is one of the most important service measures for a car. With this, you can reduce uneven tyre wear and improve the car's driving performance. If the wheel position is incorrect, the tyres may be unevenly worn very quickly. The wheel position can change dramatically, for example after driving towards a curb edge, through a pot hole in the road or towards a high asphalt edge at high speed. Incorrect wheel alignment usually increases the tyre wear and can significantly affect the driving performance. To avoid serious errors, check the wheel position as soon as possible if signs of uneven tyre wear appear. Wheel adjustment should also be done for example after the changing of shock absorbers, lining, steering joints and other suspension components.
How is the wheel alignment adjusted?
When adjusting the wheel position, the car must be positioned as straight as possible in all joints. The air pressure in the tyres must be correct. In case of deadlock/lock in the steering wheel, steering axles or wheel bearings, there is no point in performing wheel alignment adjustment.
The car is first driven on the ramp, the steering wheel and wheel bearings are visually controlled. Then we check the air pressure in the tyres. This should be the way the car manufacturer has recommended. Later, we put the special wheel clamps on all four wheels. The measurement itself begins via laser technology, according to the measuring instrument program. Camber (=inclination of the wheel plane - should not deviate very far from the vertical line of the road), caster (angular displacement of the steering axis from the vertical axis of a steered wheel) and toe (=wheel fronts are either pointing away or towards each other from the centre line) of the vehicle are measured precisely while our experienced technicians follow the measuring points on the computer. If the wheel position has to be adjusted, this is usually done first on the rear axle and finally on the front axle. Afterwards, the axle geometry is measured again.
This was only the short version of what we do during wheel alignment.
When you bring your vehicle to us, our team will be happy to show you exactly how it works and explain to you exactly why the alignment is necessary. We will be happy if you stay with us and watch what we are doing.
Many of our customers find it very interesting and informative.
