After talking to service at both the CSC factory and my dealer this is what is going on.
CSC rep: there are 3 possibilities, 1) u joint 2) bad drive shaft 3) a pen or lock has came lose on the short axle at the rear end.
Dealer rep. is now interested in finding a solution and is going to be checking things out.
I will say everyone involved was pleasant and cooperative. I told the CSC rep I was mainly documenting the problem for future reference for repair. I do not feel the trike is road worthy at this point. He agreed.
So I will add more information of the findings as they given to me.
