What Is A Wishbone On A Car

A suspension arm is a type of automotive suspension system for cars. It uses a single, large-diameter upper wishbone, usually made of steel, and two smaller-diameter lower wishbones. The single upper arm connects to the vehicle body at one end and pivots on a bearing and bushings at the other end. The two lower arms connect to the wheel hub carrier assembly, which in turn is bolted to the vehicle body or frame.

Why Are They Called Wishbones

The suspension arms are also known as wishbones because they have a 'Y' shape that looks like an upside-down letter 'W'.

How Do Control Arms Fail

The most common way that control arms fail is going over bumps in the road too fast or hitting pot holes. They can also go bad through corrosion, this happens when moisture gets into a joint and causes it to rust. The other way that they can fail is when they are overloaded with weight, which can happen if you overload your vehicle or if you have an accident.

A failed wishbone can be diagnosed by inspecting the arms for signs of damage or corrosion, as well as looking for any signs that it has been bent or twisted. If a wishbone has failed, then it will need to be replaced with a new one from an automotive store.

As they are one of the most important parts on a car its highly important you know how long control arms last, just so you know when too start paying attention to it. This way, you'll be able to diagnose an issue and get them replaced as soon as possible.
