The suspension and harder bushings my transmit more back into column than the Durango, but I think this confirms that the issue lies in the tires/wheels. We'll see what the brillant Service Department thinks of my test - I took video for them. I'll leave the tires/wheels on the vehicle until I can have them test it for themselves. In no way will I allow them to screw with rebalancing or dismounting the tires from the Durango's wheels.
I would have the discussion with them again and say you "are positive it is a wheel and rim problem" before breaking out your evidence. Just in case he/she wants to rebuke your test, let them dig the hole first.
Also slight pull added to your Durango with the bad tires is a sign of bad tire/shited belt. Just watched a full swap of tires and wheels from an in stock Journey to a customers vehicle dianosing the same issue with a field Chrysler Rep. When the original customer wheels went back on the vibration was back and it had a good left drift.
That is a lot of extra work you just did. Conviction is so much better when it pays off (not that you should have needed to do this in the first place!!)
