Okay. I was gonna contact the guy I got the SC10 off of to see if he knew what bearings he used on the diff. 'Cause I was thinking to myself, "Wow! Those bearings lasted much longer that what I normally put in my RCs". That was before I got to the bearing on the right side outdrive, it turns out that was the other contributing factor to my tranny not feeling "right " as well. Still it's weird...no crunchiness or gritty feeling to the bearing. It's just hard to turn.
