Thumping In Rear Of 04

[Booyah]

Lets see if I can explain this:

Seems like only taking a right hand turn (not a level turn) but a turn as when one side--the right (right) of the rear end will pitch up in the air and I hear this distinct thump or a thud?? You have to be going like 5-10Mph.

I thought that cant be normal but when I took the loaner 330 out I went right to that one spot and it does the same thing---weird! All I can think of is the shock or something is toping out??? any clues

Mine has the performance Package(air suspen) the loaner Reguar Suspension

Sounds like a sway bar type of issue from it going to its end of rotation
