Hello.
I removed the diff from my 240d and removed the double hex nut without measuring anything. I also discarded the old nut.
I took advice from a mechanic friend who claimed that changing the rear seal was no big deal. He didn't mention measuring anything. He also admitted to using an impact gun. My bad and will never listen to him again before checking the FSM.
Now i don't have any way of going back to the original preload.
What should the friction torque required to turn the input shaft be?
Diff is without axles and lying on a workbench.
I know this thread is old.
Please help
