Hopefully you got her going by now. You could likely disengage RWA to eliminate that. If you have the newer R62 that has spin on hydro filter you could surely spin on new one quickly. Older canister filters would just bypass filter internallly and still go into hydro charge. Remove and dump hydro filter up near engine to check for grindings. Flow and pressure tests would be next. With a little luck you just found belt tention backed off or mud in pulley. Good luck
