Yeah, the O-rings are all there... I'll be racing today and see if the car just needs more break in. But I really doubt it if the wobble will affect the handling. Hopefully not... 
We had a little wobble caused by running o'rings in both cups. I removed the rear O'ring and no wobble. We also stopped breaking rear cups, because the shaft was now deeper into the rear cup.
