Propshaft Centre Support Bearing Upgrade for E31 / E36 / E38 / E37 / E38 / E39 / E46 / E85 / E86Upgraded Propshaft / Driveshaft Centre Support Bearing Carrier for BMW E3x / E46 / E85 / E86 (not suitable for 540i) The stock centre support bearing carrier holds the propshaft in place with rubber so thin about 20 lbs of force moves it from centre to the end of its travel. While thats great for making sure no noise, vibration or harshness makes its way in to the cabin, the stock bush is extremely prone to fail, especially in harsher climates and on higher powered vehicles. Even on the best kept cars, the stock rubber bushing dry rots and cracks by the time it’s 10 - 15 years old. When the bushing lets go, it leads to excessive vibrations and clunking which can damage the transmission and rear diff. To make matters worse, the stock carrier is molded onto the center support bearing, leading to costly propshaft replacement. This upgraded unit keeps the propshaft firmly in place at all times, and its solid construction ensures it will never wear out. The thick bushings ensure the propshaft cannot move from center, maintaining propshaft alignment at all times.
Two options are available for the carrier bushings, both of which are much higher quality over the stock bushings. Close attention has been paid to the NVH (Noise, Vibration and Harshness) levels associated with this upgrade. After extensive design iterations, custom isolator bushings have been developed that separate the carrier from the body of the vehicle and mounting hardware. These carriers substantially reduce NVH levels.
Street Bushes: These absorb most of the NVH from the drivetrain. Some light NVH is possible at some speeds in the form of a soft hum. With a modified exhaust or the windows down you're more than likely to never hear it.
Track Bushes: Delivers no compromise drivetrain performance. These may create a substantial amount of cabin noise.
Both Bushes: Not sure which is for you? Try them both, they’re interchangeable
INSTALLATION METHODS:Installation does not require disassembly of the propshaft. The 2-part design clamps around the OEM bearing. The old carrier must be removed, so a cutting tool is required. This carrier is designed to avoid interference with the factory heat shields, so it has no effect on exhaust clearance.
PLEASE NOTE:This kit requires you to use the original propshaft bearing that is on the vehicle
