goin to you stering settings on your radio and set those all to o (neutral) and unhook your lingages on you truck and make shure there all nuetral adjustments/settings, then hook everthing back up and set your stering trim so it goes strait, endpoint adjustments,and your dual rate

thats all if if it was goofed before it was broke,

if it was fine before, you might just want to play around your end point adjustment on your radio , or your linkage adjustments, untill it turns the same both directions.
