Control Arms

Welcome to High Quality Store Control Arms Collection



The wishbone is certainly one of the less well-known elements in car parts. Of course, this is also due to his position, which is located directly behind the tire and directly on the wheel carrier. This finally makes him accessible only from below. Ideally, this inconspicuous component of the car will not stand out. Because just when it is damaged, the nearest workshop should be visited as soon as possible. However, since the wishbone performs hard work on every drive, it is not uncommon for it to show wear or even to be defective.

What the springs are for up and down movement is the wishbone for any sideways movement of the wheels. The tensile and compressive forces that act when starting or when braking are intercepted by these car parts and then forwarded.

Incidentally, the wishbone connects the wheels to the body and is thus a component in the suspension which belongs to the chassis.


How do I know if my wishbone is broken?

If the wishbone itself or parts of it are defective, the nearest workshop should be visited directly. Although there is no immediate danger, too much delay can lead to major problems. Not only will you notice a change in the background noise, but the steering behavior will also slow down and diminish in precision. Should not be intervened despite these features, the defective wishbone can cause further damage. Among other things, the tires can ride off unevenly. Since the forces described above now have to be absorbed by other parts of the axle, which are not designed for it, it can quickly lead to more far-reaching problems.

So how do I recognize the damaged control arm? If you are frequently traveling in your car and have already developed a good feeling for the driving behavior, make sure you quickly determine the spongy driving style. If the movement of the steering wheel is thus no longer transmitted exactly to the wheels, a defect is very likely.

In addition, the defective wishbone will also make noise. Or rather the other car parts, which as already described above, now have to intercept the forces.


When do I have to change the wishbone?

Normally, the wishbone is not a wearing part. It is made of sturdy materials, all designed for the heavy load it needs to carry. If everything goes well, it will last a (car) life and does not have to be changed at all. Since a broken or damaged wishbone, as already mentioned several times, can lead to major problems, it should at least be checked regularly. During the inspection, make sure that you also scrutinize this part carefully or make sure that this is the case in the workshop of your trust. This is the only way to avoid stress and high repair costs.

Even if the wishbone itself is changed by hobby helicopters, this is not recommended. At the end of such a procedure is namely the new attitude of camber and lane, which should always be left to the professional.


How is the wishbone structured?

The main part of the wishbone is often a construction of solid materials. The shapes can vary greatly depending on the model. A widespread form, however, is a slightly curved angle, which resembles a boomerang in appearance. This model is often referred to as a wishbone. But there are also variants in fork form. Some cars also have so-called double wishbones, which consist of two parallel wishbones. The most commonly used material is aluminum. This not only offers the advantage of low weight, but it is also rust resistant. The part of the wishbone that is connected to the body is called the wishbone bushing. This part is a so-called rubber-metal composite bearing.
