I'm at a loss... Can't determine CLUNK sound

[ss4chad]

I have this 'Clunk' sound/feel as well. I can step on the brake and give it gas and I can make the clunk come alive at will, so I was thinking Trans or Motor mount. I had previously thought it might be the rear shocks but I replaced those and the pads & rotors couple of weeks ago and it still does it.

I gotta change the trans fluid soon, while I am under there I'm gonna put a jack on the tail of the tranny and try to lift it up, then do the same with the left side engine mount and see if either are broken. If neither are broken then I'm not sure what it could be.

I have a feeling my clunk is the alignment pins that have decided to remove themselves from the chat group… FML

Did you get this issue solved? I just finished converting my 2011 XL from stock rear springs to air bags (stock height) due to my wife's bad back. The stock height conversion is working well and took the sharpness out of the rear. Things were fine for a couple of days, then, a clunking sound! I do all my own fabricating, so, I have to fix my own problems! Couldn't find anything loose. I finally tightened the spare 1/4 turn more. End of clunking.
