Control Arm Shaft Kit

Control Arm Shaft Kit

Control Arms are an important element of a vehicles suspension system. Also known as A-arms, control arms are hinged suspension links between the chassis and the suspension hub that carries the wheel, they help synchronize all four wheels, while keeping the vehicle and the suspension steady. The inboard (chassis) end of a control arm is attached by a single pivot, usually consisting of a rubber bushing. Control Arms can therefore control the position of the outboard end in only a single degree of freedom, maintaining the radial distance from the inboard mount.  A control arm set (lower and upper) connects the front suspension of the car to the frame of the car. It is connected to the wheels through ball joints, and to the frame of the car through bushings. It is usually found on the front side of the car. If the control arm is bent (can happen when you are in an accident or go over a large pothole), or the bushings wear out, it may be necessary to replace the control arm assembly.

 

When the control arm assembly is damaged, the wheels no longer work in synchronicity with each other or with the suspension. This can result in a very uncomfortable ride and can inflict serious damage to the suspension system. Usually a damaged control arm assembly will produce a few symptoms that can alert the driver of a potential problem that should be serviced including: steering wheel vibrations, which can increase as you accelerate and smoothen out once you´re travelling at constant speed. Also a driver could notice some steering wandering which will require constant correction from the driver to steer the vehicle straight.  One last symptom that could indicate damaged or worn out Control Arm Shaft damage would be clunking noises. The control arms shafts on a vehicle are very important suspension component, as they are the component that links the spindle, hubs, and therefore wheel to the vehicle’s chassis. When they become worn it can cause problems for the vehicle that may compromise handling, comfort, and safety. For this reason, if you suspect that your car´s control arms shafts may be damaged or worn, it will be recommended that you have your vehicle’s suspension inspected by a professional technician who, if required, will be able to replace your control arm assembly.
