My sister's 04 CRV had a power steering whine and I replaced the pump with an aftermarket pump but it didn't fix the whine. Unfortunately she had also been filling the reservoir with non Honda Power steering fluid and the fluid was a yellow gravy like substance. I tried getting all the fluid out as much as I could and flushed it a couple times with Honda Power steering fluid but it's still yellowish and it's still whining. Any other ideas? Is this one of those parts where it needs an OEM part? Is there any way to completely get all of the yellow junk fluid out of the entire system? Could this still be causing the whine? Thanks!
