[QUOTE="BigPSD, post: 1114364, member: 4020"] This used to happen too me all the time when I towed. Hit a bump and the bucking would start and not stop till I park it again. I racked my brain for months, thinking I needed traction bars, full leafs to get rid of the rear blocks, etc. Thought it was my tune, I know Spartan has got its fair share of blame out of it on other sites... Wanna know what it was? Play in the hitch, there was about 1-1.5mm of play in the hitch receiver and the ball mount. I was also using an adjustable drop hitch. The slider also had a tiny bit of play. I guess at those speeds, and with certain amounts of weight, once you let the setup slack and introduce motion, it just goes thru the whole truck... It could be the other things posted but its worth a look... Now if I could just figure out the 2-1st gear slam shift at low speed...:cursing: [/QUOTE]
