During my maiden run with Sushi drift tires, I heard a clicking noise coming from the rear of the car (TB02). I came home and looked at the spur and pinion gears - no problems. Prior to the run, I tightened the screw on my rear ball diff so that there was little slip and both wheels turned together. Now, even though the bolt is still tight, the tires are turning in different directions like before I tightened the main bolt Could the clicking noise be coming from my ball diff.? Anyone have any ideas or directions to point me in? Thanks

Well I pulled my motor off the mount - replaced and the darn clicking went away - any ideas to the cause?

could be a rock in your gears.
