Thought I should add one last tip / piece of info.

You have read that I have a rear driveline vibration issue since the lift install. I know several others do as well. Calmini has been working on a solution. They have it done. It is essentially a double cardan type of joint at the top of the driveline. JE Reel did Calmini's. Calmini will be adding to their sales literature that this may be something others will have to do if the vibration is present.

I called and confirmed with JE Reel and they have made two thus far. One for Calmini and one for a Calmini vendor. Not cheap.
