Hey, :helpdoes anyone know what the seal part number is for a 540i steering gearbox. I'm talking the sector shaft seal. Mine leaks helping to ruin the link bushings.:eek: Does anyone have any pics of a disassembled gearbox. I've seen the parts diagram for box in other treads but not an exploded view or pics. Why are rebuilt boxes so damn expensive other than the liability because its part of steering system.:mad Seems to me its a fairly simple system with few parts. Mine works fine except seal is leaking which I assume I should be able to xref and buy locally.
