Chevrolet Tracker Control Arm With Ball Joint

The control arm is part of the mechanism of the automatic suspension. Often known as A-arm, the wheel between the axle and the upright or hub suspension is primarily a hooked suspension bridge. There are several parts of the control arm with ball joint, the inside (chassis) end of the control arm is connected by a single hinge, normally a rubber bushing. The outboard end position can be controlled in a certain degree of freedom while the radial distance is maintained from the internal brace. The lower link of the suspension is created by several control arms. In a few car designs, they are used as the highest part, usually with a lower wishbone. The extra radius rod is then connected to the upper arm.

The control arm primarily attaches the wheel hub to the vehicle frame and the steering knuckle. For driving comfort and handling, the Control arm bushings are important. They help stabilize the suspension system, which allows noise and vibrations to be controlled, as well as providing a smoother ride over bumps.

We need to learn first how the control arm is attached to the vehicle to be able to understand how it is functioning. On one end the control arm is connected by a ball and socket called a ball joint to the steering knuckle (at which the wheel is attached by hub and bearing assembly). The other end of this is connected to the frame / body of the car. And if the vehicle goes over a bump, the control arm swivels up and down with the wheel, allowing the body of the vehicle to stay steady. The control arm also has a bushing (or a pair of bushings) on the side of the frame / body allowing it to rotate smoothly.

The control arm attaches the hub wheel and the knuckle steering to the vehicle frame. The come is fitted with bushings on the vehicle's frame side and a ball joint on the vehicle's wheel side, allowing adjustable and controlled movement according to the driver's road conditions and steering feedback.
