Welcome to FTE. It sounds like you're on the right track. I'd check the diff fluid level first just to be on the safe side, then try rotating the tires.

Remember noise tends to travel and may be coming from the front too so don't rule that out. I had a noise that everyone that rode with me told me was from the rear when I thought it was the front. Turned out to be a bad shock on the right front that ruined the tire, but it was hard to pinpoint.

Good luck and keep us posted as to what you find. I'm sure we can come up with more suggestions if needed.

No it's not too common. The PIA question kind of depends on your skill level and how much time you have on your hands.


That's the standard FOrd 10.5 rear with no limited slip. Your may look different depending on which axle you have.
