I have had this problem with several toys. for me the prob has been cheap springs, bent springs, and when a total rooky putting them on the wrong side. On a lot of the springs it is marked which side they go on since as one person said the spring perches are not the same. Also have had bad springs in the back that will also make the truck sit tweaked. Another thing that I thought might make it sit funky is the bar thats bolted between the frame and front axle. I assume its some kind of torsion bar to eliminate wheel hop, but since its on one side I think it could possibly affect the way the rig sits. good luck and keep us posted on what eliminates the prob.
