Clunk and billies

Installed my bilsteins today and set em at 2.5. Now there's a clunk when I hit bumps :/
Haven't put aals on yet but did put the 285/65/18s on.

Everything is back the way it went and no parts left over.

Heeeeeeeellppp me
(said like Nathan lane in the producers remake)

 

Did you by any chance remove your swaybar links to get those installed?

Many times I have not tightened those things back down enough and gotten
that clunk you describe.

 

Did you double check every bolt or nut that you removed, loosened, or even looked at?

I too have forgotten the swaybar link. Took me about a day of wondering why the truck handled so differently.
