A control arm assembly, otherwise known as an A-arm assembly, is a vital part of most passenger vehicles. They essentially link the steering wheel and the chassis of the vehicle, making it possible to steer. However, like all parts on a vehicle, they do wear out and need parts or all of the assembly to be replaced. Over time, the bushings and ball joints that are in the control arm assembly wear out. There are three main signs that your control arm assembly is going out.
The first sign that your control arm assembly is failing is vibration, usually felt in the steering wheel as you're driving. The steering wheel will actually shimmy, and the vibrations of the vehicle can be felt in the wheel itself. This vibration may increase with the speed of the vehicle and then smooth out once the desired speed is reached.
The second sign that the control arm assembly is failing is that the steering of the vehicle will begin wandering. Excessively worn ball joints and bushings will cause the alignment of the vehicle to shift, which will cause the steering of the vehicle to pull to either the left or the right of the center. It can make steering your vehicle increasingly hard to do, and if you let go of the steering wheel as you're coasting along, you'll notice that your vehicle will not continue going straight ahead, but will start to veer to either the left or the right of center.
The third sign that your control arm assembly is failing in your vehicle is clunking noises. The clunking noises are caused by the bushings or ball joints developing excessive play in them. The looseness and excessive play will cause them to knock during take off, and that will cause loud clunking noises to take place that is noticeable to the driver.
Once the clunking noises begin to take place, it is important to get your vehicle in to see your mechanic, as it is your vehicle reporting to you that there is too much play in the bushings and ball joints of your control arm assembly.
