While troubleshooting some erratic higher temperatures and less sharp throttle response, found that my center diff pins has warn into the cup sideways, causing grooving and odd handing. Running 5/5/4.

Question however. When I put the back rear of most other buggies on the ground and rotate the front tires, there is a moderate amount of resistance. This does not appear to be the case with the NB48. There is a slight hint of resistance, but it's much more free. I'm wondering if this is normal and can I stop searching for another issue (which I'm failing to find)?
