Rear Trailing Arm Bearing Set for E87 E82 E90 E91 E92 E93 2005-2013, for X1 E84 2010-2015, Replace for 33326763092 The rear suspension system for E9X platforms features a complex multi-link design with five links per side.The trailing arm connects the subframe to the main axle using bushings.Standard rubber bushings are susceptible to deformation under aggressive driving conditions such as hard braking, acceleration, and cornering, leading to changes in camber and toe alignment.This can result in handling instability and reduced steering , which affects dynamic function.This bearing set provides an upgraded solution by replacing the factory bushings with monoball joints.The monoball design allows for precise, low-deflection movement, improving response and maintaining consistent suspension geometry during dynamic maneuvers.A sealed cover design helps retain lubrication and prevents , contributing to extended service life compared to standard spherical joints.These bearings are engineered to fit directly into the rear trailing arm or can be adapted for use on the outboard upper arm with custom washers.Constructed from 40Cr steel, the set includes four monoball units and is designed as a direct replacement for part numbers 33326763092 and 33 32 6 763 092.Fitment: 1 Series E81 E82 E87 E88 2005-2013 3 Series E90 E91 E92 E93 2005-2013 X1 E84 2010-2015 This is a replacement part from a third party.All brand/model references serve only to show intended compatibility.
