Yes the slipper clutch was the problem. i figured it out last night when i was running the truck with no body on, it was waaaay too loose. i tightened it too tight i think so i will check it out later today. i havent been able to find a allen that will fit the diff assembly, i need to go buy some more i guess.. after i tightened the slipper last night it acted normal again. i dont know if i like the new gearing tho. it took quite abit off of the bottem end and the top end isnt to noticable. i thought i would enjoy more speed but i think i enjoyed the torque more.
