Upper Control Arm Assembly The upper control arm assembly is a critical suspension component that attaches to the frame of a vehicle and connects directly to the steering knuckle or strut housing. Its primary function is to support the movement of the wheel and provide stability during cornering maneuvers. The upper control arm's inner end bolted to the frame, while its outer end connected to the steering knuckle via a ball joint. The design of the upper control arm typically consists of a sturdy metal rod with a spherical bearing at one end and a pivot point at the other. This setup enables smooth movement between the control arm and the steering knuckle as the vehicle navigates through various driving conditions. In addition, some modern vehicles may feature an adjustable ball joint that allows for precise alignment adjustments. When inspecting or replacing the upper control arm assembly, it is essential to ensure proper alignment of the vehicle's wheels. Misaligned components can lead to uneven tire wear and affect overall handling performance. During replacement, it is recommended to utilize a wheel chock or other safety device to prevent the vehicle from rolling while working underneath.
