I was out yesterday with my buddy...came to a light turned green gave it some gas and the whole truck just shook pretty wicked. . . now im thinkin it was axle hop, which ive never had in this truck before. the tranny doesnt always want to come outta first..its a rebuilt tranny with only 17k on it, not sure if its the tranny or if i destroyed something in the rear or even if its my driveshaft, i checked it out in a parkin lot and didnt see anything leaking. so im just wondering what you guys would think it could be...i havent heard any noise comming from the rear or any odd noises other than some brake squeal.

Sounds like transmission issues, my moms explorer did the same thing and it was her transmission not downshifting her neutral safety switch was on its way out...
