I took the liberty to do a little research based on the numbers you have provided.
You state that you have a tongue weight of 850 lbs and you are using 1,000 lbs spring bars...you are within your tow rating and your GCWR...However you are WAY overloading your receiver.
Here is an excerpt from the 2014 Durango owners manual that addresses this issue.
So...
1) You have 130 lbs too much tongue weight
2) you have 270 lbs too much spring bar pressure (potential)
What does this mean?
Basically, your receiver is overloaded and more than likely flexing under the load/torque from the WD bars.
LT tires are great, The Sway Pro is a great hitch and the spring bars are appropriate for the tongue weight... but receiver flex will cause issues... really bad issues eventually.
In light of this I would crawl under the Durango and check the welds on the receiver for cracks.
Thanks!

Wrong. My class IV hitch is rated at 14,000 lbs and 1,400 lbs tongue weight. The hitch isn't 'cracking'.
Also wrong on the tongue weight max. The physical manual that came with my truck does indeed show 750lbs max but also clearly states that what matters is not to overload the rear axle, which I didn't.
I know this because I weighed it and have 400 lbs to spare.
The 2 best guesses are to increase the tire pressure and/or lower the hitch 1 hole, even though it is already level.
