Hi Marlin,
I did check what you said. I have about 2+ inches of clearance in the rear.
Here's some more detail on the noise:
- Happens at highway speed 65+
- Sounds like metal to metal *vibration/grinding... but more on the vibration side.
(sequence):
- Steady gas at 65 mph, remove foot from gas.
- Grind Grind Grind (3 seconds)...then GONE. Like something released.
It's freaky! Does this sound familiar to anyone at all?
