Introduction
The control arm is a key part of your car’s suspension system, connecting the wheel hub to the vehicle’s frame or chassis. It allows for smooth vertical movement of the wheels while keeping them aligned with the rest of the vehicle. In simpler terms, the control arm helps your vehicle’s suspension absorb bumps and maintain stability when driving over uneven terrain.
There are two types of control arms in most vehicles: upper control arms and lower control arms. These components work together to maintain the geometry of the suspension, ensuring proper wheel alignment and control.
- Upper Control Arm: Found at the top of the wheel, it helps control the movement of the wheel and keep it in place.
- Lower Control Arm: Located beneath the wheel, it bears much of the vehicle’s weight and works in tandem with the upper control arm to ensure the wheels stay aligned.
