Thanx for the info. Will the diff oil run out of the Diff or does it have to be drawn out since its so viscuous.
is making sure the allen wrench you use is short enough to get in there. I cut one off to make a short bit and use a wrench on it. For the oil I would use mobil one synthetic if you can't get redline on short notice.
I am going to replace the diff oil this weekend in my 89 525i. The process looks simple. Are their any snags that I should look for or parts that should be replaced - like the drain plug, washers, etc? Can anyone recommend a quality diff oil?
