Show original supplier description
The BMW Control Arm and Ball Joint Assembly is a critical suspension link that connects your vehicle's suspension to the subframe. When the bushings and joints within a control arm begin to wear, drivers may experience a noticeable looseness in the suspension. Symptoms of a failing control arm include play in suspension joints, buckling noises, uneven tire wear, difficulty with vehicle alignment, and vibrations or wandering sensations felt in the steering wheel, especially at highway speeds. It is presented as an economical and robust alternative to original servicing and repairs, suitable for professionals and discerning car owners seeking a high-standard repair. This part is intended as a direct replacement for the front left lower control arm. This control arm is compatible with the BMW 3 Series, specifically the 320i and 323i models from the E21 chassis, with production dates from October 1978 through 1983. Specific fitments include various 1978-1983 BMW 320i models (Coupe, 1.8L and 2.0L engines, both Automatic and Manual RWD). It is also referred to as a Wishbone by BMW.
