Overview

The Lemforder Rear Wishbone Control Arm is a direct replacement for the left rear upper control arm on the E39 5-series. Control arms are critical suspension components that can wear over time, leading to issues like sloppy vehicle control, steering vibrations, or knocking sounds. Replacing a worn control arm with an OEM Lemforder part restores control and suspension quality.
Show original supplier description
The Lemforder 33326767831 is a direct-replacement rear upper control arm, specifically for the left side of BMW E39 models including the 525i, 528i, 530i, 540i, and M5. Control arms are a critical link in a vehicle's suspension system, connecting the suspension to the subframe and allowing for articulation as the vehicle navigates road imperfections or corners. When the bushings or ball joint within the control arm wear out, it can manifest as a looseness in the suspension, knocking noises, uneven tire wear, difficulty in achieving proper alignment, or vibrations felt in the steering wheel at higher speeds. This Lemforder control arm addresses these issues by providing a complete replacement, including the necessary installed bushings and ball joint. Lemforder is recognized as a top brand in original equipment (OE) steering and chassis components, serving as a trusted partner to numerous vehicle manufacturers worldwide. Their products are known for meeting exacting factory specifications, often being manufactured on the same lines as genuine BMW parts. This OE-quality control arm is an excellent option for restoring original ride quality and handling to your E39. This product is designed to fit the BMW E39 chassis, specifically the 525i (M54 2.5L), 528i (M52 2.8L), 530i (M54 3.0L), 540i (M62 4.4L), and M5 (S62 5.0L) models. Please use a vehicle selector to confirm exact fitment for your specific vehicle.
