Product Information

Updated tension strut for newer model X3's, will also required updated ball joint

Your BMW's tension struts are an integral part of the front suspension. This control arm is essentially tasked with locating the front suspension. The most common failure of this control arm occurs when the inner bushing fails which causes play in the front suspension. The bushing can be replaced but it requires a bushing press with the correct adapters. More times than not it is simpler and easier to just replace the entire assembly with the bushing pre-pressed in.

For vehicles built before 12/2006 that still have the original control arms installed will require updated ball joint, part number 31103438623. The newer tension struts have a thicker mounting area for the ball joint compared to the originals making the original style ball joints too small.

Suspension Control Arm and Ball Joint Assembly

Control arms are crucial link in a vehicle's suspension connecting the suspension to a vehicle's subframe. These pieces are usually hinged to allow for suspension to travel and articulate as the vehicle rides over obstructions in the road and while the vehicle turns. Many vehicles such as those with independent suspensions have multiple links and feature several connection points and arms to offer better ride quality and comfort.

As bushings and joints in a control arm begin to wear you may notice a looseness feel in your suspension. And while many arms have replaceable and serviceable individual components, many still require the replacement of the entire arm. Below are signs of when a replacement control arm may be needed:

Suspension Control Arm and Ball Joint Assembly Failure Symptoms
  • Play in suspension joints where these arms meet the subframe and/or knuckle
  • Buckling noise emanating from the suspension
  • Uneven tire wear
  • Inability to properly align vehicle
  • Shutter or vibration coming from the steering wheel at highway speed
  • Wandering or pulling sensation from side to side felt on the steering wheel
