Finally put new combo on the road last night. I have a couple of problems still but right now the easiest one seems to be the toughest. When I leave out of the hole hard there is a loud ratcheting sound that matches drive-train speed..It only happens under hard accel. in first and second, about three seconds, also noticed when tight corner under acceleration, cannot seem to find anything binding. It feels like in the area of passenger feet area. I hope it is not internals of G-Force. The best way to describe the sound is if you have a Ford p/up with auto hubs that are not engaging.
