I finally think I have the clunk figured out in the Jeep. I was researching the right fluid to use when I came across this on eatons website...

When I step on and off the gas pedal, I hear the unit make a “clunking” noise. Why?
Because Detroit Lockers have “backlash” or “slack” between the drive and driven teeth and you will hear this in everyday use going through corners and when going from drive mode to coast mode. Also with the vehicle on the ground and the transmission in neutral you will have 1\4 to 1\3rd of a turn of lash in the driveshaft, this is completely normal.

Atleast I know what it is. Just don't remember it being that way on 2" of lift... I guess it changed from the additional 2"? I think my trans mount is good though. Just need to fix my leaking pinion seal in the rear.

Give the mount a GOOD look down when you do your belly-up. Might as well buy a new one if it looks like it might be causes vibes. You can get them for $25 at RockAuto.
