Clear BMW chassis

Please ensure your correct model is selected

Control arms, and their integrated ball joints, are some of the most crucial components on a BMW suspension. The control arms literally control the wheel and suspension as they go through their range of motions. They do more than just keep the alignment in a constant spec - they are a vital locating component for the suspension itself. A faulty or worn control arm or ball joint is a very dangerous and potentially life-threatening problem so make sure they are inspected and replaced at regular intervals.

Most control arms for BMWs consist of an inner and outer ball joint made of plastic, rubber, Delrin, or metal and covered in grease with a rubber boot to seal it from the outside. The ball joint rotates and spins as the control arm goes through its movements and that will wear the ball joint and make it loose. The grease inside the housing can also get used up, evaporate, or become contaminated from moisture and foreign particles. As the ball joint becomes worn it can result in excess movement within the housing. Your steering and handling will become less precise and there is usually a light clunking or clicking sound. In rare and extreme cases the ball joint can separate from the control arm completely, leading to a total loss of suspension and steering control. You should have the ball joint play checked annually and replace them every 3-4 years. Most track organizations will not allow a car if they are older than three years.

Control arms also take abuse from impacts and handling forces. Aluminum control arms will generally bend and prevent an accurate alignment. Steel control arms will crack and fracture and require close inspection annually and replacement every 3-4 years.

We sell OE BMW, OEM, and performance upgrade control arms from proven manufacturers. The control arm is so important to a BMW suspension that we insist on only top quality brands and designs and will never sell a control arm based on price alone. We also have upgrade packages with superior designs and better bushing options and we have bundled these together with valuable package savings.

Turner Motorsport refresh kits will not only rejuvenate the suspension in your vehicle, but improve it to better than new with select upgraded components. Symptoms of a worn suspension include a loose and imprecise feel to the steering, excessive shaking through the steering wheel, or sounds like squeaking, grinding or clunking. This kit will not only help address these issues but is designed to have superior performance compared to stock, and extend suspension life. The Turner engineering team set out to design a no-compromise solution that requires no modification and offers instantaneous cornering and braking response. Our control arm bearings utilize a unique grease-able spherical bearing that is both serviceable and replaceable, with integrated dust seals to help keep dirt and moisture out. This bearing offers considerable improvement in both precision and durability compared to other unsealed poly and delrin bushing inserts previously available, which can wear prematurely due to contamination. The bearing assembly utilizes the highest quality materials, precision machining quality, and components to ensure a perfect fit and longest lasting component life possible. These Turner rear trailing arm bushings (RTAB) now feature a much sought after sealed design. Turner recognized the popularity of their original RTAB design as well as the customer demand for this sealed upgrade, ultimately utilizing the same concept at the front control arm monoballs. A sealed design means not only that contaminants such as salt, grit, and road debris will not affect the bearing, but also means they require no lubrication or maintenance - ever! Adding strut reinforcement plates will help prevent the deformation of the strut tower and possible cracking. Upgrading the rear shock mounts and adding reinforcement plates is highly recommended because of the known failures with the mounts ripping apart. Replacing the lower trailing arm bushings with a ball joint will not only give a more solid feel in the suspension but last longer due to its rubber seal design.
