I am in need of help, I have recently changed the diff on my 850 as the previous one was whining. The issue I am having is that the passenger side driveshaft is pulling the output flange out of the diff. This was not happening before and is obviously a problem as it leaks out all the oil and very quickly becomes undrivable because it starts catching on everything.
To fit the new diff I had to change over the output flanges but I doubt it is a problem with them as the drivers side is fine and I have swapped the output flanges over and this had no affect.
I have no idea where to go next as I don't know why it is doing this. Any help would be great.
Thanks very much.
