Detailed Description

This suspension knuckle bushing is built for BMW rear suspension service where the original bushing has worn, cracked, or lost its ability to maintain alignment and control. Dorman 540-133 is engineered for the rear lower forward position and is listed across a wide range of BMW 1 Series, 2 Series, 3 Series, and 4 Series applications, including 2012-2021 BMW 320i, 2014-2021 BMW 220i, 2016-2020 BMW 420i, and 2017-2020 BMW 430i models. It also cross-references BMW 33326792551 for the same application.

What It Helps Fix

  • Rear suspension clunking or looseness from a worn knuckle bushing
