I had a rumble in the suspension at 45 mph and above that I suspected was a driver side front wheel bearing on my on my 2005 AWD Dodge Durango. Normally you diagnose this by a wiggle test while the truck is up on the rack, but my vehicle had no play at all in the front wheels.
Carl was able to diagnose the problem as being the PASSENGER side wheel bearing, not the driver's side as I thought.
He fixed it that morning for a fair price.
I give him 2 thumbs up.
