BMW E92 335i QUAIFE LSD install

Ill post few photos and do write up about this upgrade so Peter could copy this to his own thread about his new toy :wink:

Car - BMW E92 335i automatic
QUAIFE LSD unit
Diff side shaft seals
Mobil 1 75W90 fully synthetic gear oil
Loctite 270 for crown gear bolts
BMW gasket sealant for diff back cover and few hours of work

Diff removed from the car , only with help of "smallest" spanner in my garage , i believe in many others garages is one of the smallest as well :happy:

Drained oil , removed side flanges , removed side seals , removed back cover ,removed side bearings and finally main dif part is out of the casing . Fully stripped out , removed all bearing parts .

Diff is back in car , filled oil and did first test drive , lot corners to get LSD unit fully lubricated for perfect performance and main think its longer life . No other tricks needed , so thanks again for Your time reading this short story ,and best of motoring for Peter !

Outstanding work as always.
