I own 2 2003 Range Rovers, one that is Java black and the other Chawton White. The white one does not turn as easy or as smooth as the black one. Its not difficult to turn but it feels way heavier than the black one when parking, pulling off, or turning. Ive checked the power steering fluid, and there aren't any codes being thrown. Does anyone have any idea of what I may need to replace? Ive looked into the RSW All Comms tool, replacing the steering pump, servatronic valve or the BCU. Thanks for the help.!
