Ron, I learned long ago not to try to argue a point with you (:W) BUT notice that Ben said "So it DOES NOT transfer as much weight to the front axle as a traditional receiver would with the same WD spring forces." (Bold added for emphasis) I still think his point was valid.:)
Who knows what is going to solve the OP's problem. It could very well be that he simply needs to tighten up his WD chains BUT it is also possible his receiver is bending like so many others have. It is something he should check on instead of being unaware of a possible problem.
