After I checked under my truck, I so that the driveshaft was 2 inches out of the tailshaft, the manufacturer tolerance in that part is 1 inch, so the solution seems to be extending the driveshft aproximatelly 1 inch.
After I modify that, I will post another topic to tell you if it works.
Does anybody knows who makes a slip yoke eliminator kit for the NV231HD?

I think that is well worth the price, you will have alot less driveshaft clunking.
