So just to eliminate items as I go thru this. I pulled the wires that run thru the tubes and found no issues. I cut off all connectors and am headed to get parts to replace this stuff. I wonder if there is a chance that it could be inside one of the wheels? I'm thinking not as when the brakes worked all four tires slid on the gravel. I have Dexter never lube axles and although I have had one off and back on I would rather not go there. My fear now is that it could be something inside the belly of the fiver and that is a real chore, and I have been there in the past too. I have owned this rig for 12 years and put lots of miles on and doing all the maintanence myself, I pretty much have seen it all.
