So I have and 08 with 201000 on it and I recently started hearing a grinding sound when I drive. I put it up on jack stand, checked the tires for odd wear and bubbling, there was none. Tried wiggling the tire top to bottom and front and back there was no play on either. When I started it and ran in reverse and grinding sound started but went away after a bit and both hubs spun. In drive sound is constant and only the passenger side spins. Sound seems to be coming from trans but hard to pinpoint. Anyone having this issue?
