So i picked up a used b4.1 in trade with a lip sxxx v2 and peak racing 7.5 turn with a 50c 5000 mah lipo. Redid all the shocks and went through it real good. Ball diff felt notchy to me, so I tore it down to look. Everything looked good, so I cleaned it with motor spray. Sanded the rings, cleaned again. Put it back together and oiled tranny with some 25 weight shock oil. Tranny runs smoother, but the diff itself still feals really gritty. If I hold a tire while on a stand, it diffs fine with throttle, but still doesn't feel right working diff by hand. First 10th scale buggy because all i have raced before is nitro 8th scale. I am used to gear diffs. Watched building and tuning ball diff videos and don't see where I went wrong. Any suggestions? Everything else working great after cleanup.
He is putting the shock oil on the gears, not in the diff. If you do this only put a drop or two.
