Unicorn Egg - Billet Aluminum Front Diff Solid Bushing v5.0
Application: E39 Sedan & Touring Wagon
Description: Replaces the OEM rubber front differential bushing that is prone to premature failure, causing vertical movement of the differential which adds undue stress to the bushing mount. Continued movement of the differential leads to failure of the front diff mounting bracket. Installing this billet aluminum bushing eliminates the possibility of any movement of the differential and is inexpensive insurance against failure of the diff mount breaking off the rear subframe. This solid bushing will not add any noise, vibration or harmonics because the 2 rearmost diff mounts are maintained with OEM rubber bushings. This updated version 5.0, incorporates a flange stop at the rear edge of the bushing which eliminates any potential forward movement of the differential especially for those who prefer to use polyurethane bushing upgrades for the rearmost mounts of the differential.
