The ///M limited slip differential is know for a grinding noise during low speed cornering. When the rear wheel speed differential varies during tight cornering, a slip stick effect is created on the lining and steel discs incorporated in the differential locking clutch, causing the grinding noise.
This is the new fluid described by BMW to cure this problem (TSB# 33 01 02)
Often overlooked, scheduled rear differential service is very important. Over time gear lube breaks down causing bearings and internal components fail. Regular maintenance will keep your vehicle running properly for years to come.
ECS rear differential service kit includes:
* Three bottle of Genuine BMW Limited Slip Gear Lube
* Two New Genuine BMW Drain/Fill plugs
* Drain plug O-ring
