Hi Guys,
I stripped the car down today, and I found a problem with the front one-way bevel Diff ring gear. I'm not sure if it came this way or was it my doing, but two teeth on the ring gear were slightly bent causing the drivetrain to feel "notchy" at that spot. It looks as if it was not molded properly. I checked the two other one-way diff ring gear that came with the kit and found those to be okay. After replacing it the drivetrain now feels much smoother than before.
