Needs some help, I know it has been discussed, but not sure when. My sc10 4x4 grinds when on power and I get little acceleration. I'm running a trinity monster up 4.5 and Im using the chassis stiffener. I have replaced both diff, belt, belt gears, and my clicker is tight, also my belt tension is one notch from the bottem in the rear and almost the same up front. Diffs are not leaking and are filled to the specs in the manual. I consider my self a pretty good wrench, but this is got me stumped. Any suggestions. Pm me if u would, thanks a lot
