* More information about control arm
In automotive suspension, a control arm, also known as an A-arm, is
a hinged suspension link between the chassis and the suspension
upright or hub that carries the wheel.
The inboard (chassis) end of a control arm is attached by a single
pivot, usually a rubber bushing. 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.
This is in contrast to the wishbone. Wishbones are triangular and
have two widely spaced inboard bearings. These constrain the
outboard end of the wishbone from moving back and forth,
controlling two degrees of freedom, and without requiring
Most control arms form the lower link of a suspension. A few
designs use them as the upper link, usually with a lower wishbone.
The additional radius rod is then attached to the upper arm.
