How does the control arm assembly work on a car?
The control arm assembly connects the vehicle’s suspension to the wheels via ball joints, and to the frame of the car via bushings. Your vehicle has four control arms – one for each wheel – and they help synchronize all four wheels, while keeping the vehicle and the suspension steady.
How many control arms do you need for rear axle?
This also means one less ball joint, and a couple less rubber control arm bushings to worry about. For the rear of a vehicle with a solid axle, any style of control arms might be used to connect the rear axle to the frame or unibody. Most often, it is three or four control arms with rubber bushings on each end.
How is the position of the arm controlled?
It can thus control the position of the outboard end in only a single degree of freedom, maintaining the radial distance from the inboard mount. Although not deliberately free to move, the single bushing does not control the arm from moving back and forth; this motion is constrained by a separate link or radius rod.
When do you need an adjustable control arm?
