While I had my subframe out I fixed my leaking steering box. Mine was leaking from the input shaft.
Compiled by _z_ from the form post How to fix leaking steering box input shaft seal
I had the steering box on my work bench and I was able to remove the shaft seal without taking the steering box apart. I did this by poking a small screw driver along the side the input shaft and into the inside edge of the seal and prying up, working my way around. I was so happy when the thing popped up! At first I tried poking a hole in the seal to dig in an pry up, but the seal started getting pushed in and I found that the seal had metal inside it. I had already obtained a replacement seal The size is metric and marked on the seal that I read with a magnifying glass.
18x30x7 shaft seal.
I got mine from Motion Industries for $2.17 as I could drive to one of their places.
When I got it the packaging revealed that Motion got it from this place that might come in use for someone.
I hope the pitman arm end of the thing doesn’t start leaking because that will be a bear to get the arm off.
Most bearings and seals have their specs on them so you can usually get a replacement for these from a generic dealer if not BMW. I got my transmission bearings and seals this way, years ago.
