Product Overview

The rear lower rearward control arm, OEM number 33326792533, is fitted across BMW's shared F-chassis lineup, covering the F20/F21 1 Series, F22/F23 2 Series, F30/F31/F34 3 Series, and F32/F33/F36 4 Series, including xDrive AWD variants. Used on both the left and right sides, this control arm spans one of BMW's highest-volume shared platforms, making it a high-turnover part number worth stocking in volume.

Worn control arms typically show up as clunking or knocking noise from the rear suspension over bumps, uneven or accelerated tire wear, or a looser overall ride feel. GSK Auto manufactures this control arm to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is a Control Arm?

Function: The control arm connects the vehicle's chassis to the rear wheel assembly, allowing controlled suspension movement while maintaining wheel alignment.

Working Principle: One end of the control arm mounts to the chassis through a rubber bushing that absorbs noise and vibration, while the other end connects to the wheel hub or knuckle, allowing the wheel to move through its suspension travel while maintaining proper geometry.

Importance: On BMW's high-volume shared F-chassis platform, a properly functioning control arm is essential for accurate wheel alignment, stable handling, and even tire wear.

Common Failures & Signs: Worn bushing causing looseness or play. Clunking or knocking noise over bumps. Uneven or accelerated tire wear. Vague or unstable handling feel.
