Lower Arm Rear Left

Often known as wishbones/track control arms, suspension arms come in all shapes and sizes. The primary job of suspension arms is to mount the suspension to the frame of the vehicle and to help maintain the geometry of the suspension supporting a wide range of movements. The most common problem is that of the bushes wearing out causing unwanted movement leading to terrible noise. 
If you are suffering handling problems or bad tracking, or your car feels like it is 'leaning' or not responding well, then you may have a suspension arm issue. The suspension arm is an integral part of your car's suspension system and helps support the vehicle body above the chassis and axles. It is important that your suspension arms are working efficiently as they play a vitally important role in helping dissipate shock and making sure that your car is handling properly. Suspension arms for every make and model of car are vital components of car's suspension system.
