TECH 53 - BMW E46 Rear Differential Bushing

We know how weak the factory rear differential bushing is. It starts to crack over time. A failing differential bushing puts additional stress on other components of the rear axle and drivetrain. Keeping the differential properly mounted and aligned ensures that other related components, like the driveshaft and rear axle, are not subjected to undue stress.

The OEM unit will wear very quickly under spirited driving. The sign of a worn bushing is a loud clonc under big acceleration or when clutch kicking.
We have designed this E46 rear differential bushing so that it last in motorsports application. We made the bushing out of Delrin, and the inner sleeve in strong and lightweight 6061-T6 aircraft grade aluminum. Delrin is resilient, but not enough to produce flex. Compared to Aluminium, the Delrin bushings are more comfortable to drive with. In fact, you don’t feel any new vibrations when it’s installed.
In order to renew all differential bushings, we recommend you match this kit with two of our front diff bushings.

This E46 rear differential bushing replaces part number 33176751808.
