Frequently Asked Questions


How does car steering work?

There are two basic types of steering systems; Standard Mechanical and Rack and Pinion steering.

The major difference between the two is that the Rack and Piston system has fewer parts and pivot points, which results in more accurate control and higher responsiveness.

However, this system has a higher chance of leakage which means the steering rack assembly typically requires replacement more often than Standard Mechanical steering.


How does car suspension work?

car-suspension

Suspension is essentially the shock absorbing part of a car which allows the wheels to remain in firm contact with the road while maintaining traction, it also helps provide passengers with a comfortable ride.

The suspension in your car is mainly comprised of springs and shock absorbers which come in all shapes and sizes depending on the vehicle.

Suspension removes a huge amount of vibration and bumps from a car as well as internal noise, so it will be noticeable if something is broken!

Even if your car drives smoothly and comfortably it is always a good idea to have the steering and suspension checked at least once a year.

There are many forces being applied to your steering and suspension as you drive along which means the two systems can be subject to stress from every angle. This means there are many areas which could be affected by driving.
