Front Left Control Arm, OEM - E46 non-M, Z4

This is the E46 OEM Lemforder control arm, one of the original suppliers to BMW for many suspension components. E46 control arm ball joints last approximately 2-3 years and then show signs of wear (much sooner with track/autocross use). It's absolutely vital to regularly inspect your control arms, ball joints, and bushings for wear and fatigue before it becomes a dangerous safety issue. Your ball joints may have a level of wear without you feeling it through the steering wheel or chassis. Fresh ball joints also tighten up the handling and steering, giving you a more direct steering feel and more confident handling. If you feel some of your BMW handling crispness is gone, check the E46 front lower control arms and bushings. We sell several different types of control arms, as well as bushings, depending on your budget and intended use. This is the OEM E46 front control arm, as your car was originally equipped. There are also HD and ZHP control arm upgrades available.
