my power steering pump is Sreamming any time i increase RPM's. I took the pully off and shot some WD-40 in the front of it, stopped for a day, now it is back again. pump still works great. Figure i will have to replace the pump. checking around, it seems e31's use a different pump then the 540 or 740 m60 engines. Not really sure what the difference is, as they both also use Pentosin. I have access to a 94 540 pump, does anyone know if that would fit a 840? Thanks
