yarikoptic,
I think I may have solved this issue. I jacked the right side, started the car and put it in drive. As the CV was spinning I watched the stub at the differential and accelerated the engine slightly. I was surprised to see the stub push out under centrifugal force approximately a 1/2 inch or little less. If this happened under a load, I predict that while pushing out, the CV joint would spin out of round which would cause my wobble/vibration.
I am going to pull the CV this weekend and see how much I can pull the stub out of the differential.
Let me know what you think or if you have other opinions.
Thanks.
