Its a link suspension. When you say control arms, you are referring to the
double A arm configuration. In the 4wd trucks, the axle is linked to the
frame with four links and a track bar. Control arms literally control where
the ball joint is located, while the links are fixed except for one bolt
that should be set at the factory and need never be touched unless something
well out of the ordinary happens. The particular reason for differentiating
is because in the link suspension, the bolts are rarely touched, thus its
very rare they are loose. They should be permanently set for the castor of
the axle. In the 2wd, the bolts will be loosened in each alignment
procedure.
Since the OP says they went over it, the most likely spot they didn't find
is the track bar and the steering box. Neither will do anything too goofy
when the truck is on a lift, since the track bar is under tension, and the
steering box has no load. Also, a link bolt probably won't make much noise,
since its always under compression load, but that depends on how the truck
is driven, such as if it leaves the ground. The bushing on the other hand,
might be a source of noise if its worn.
Just my take, having had several "clunks" end up in now the fourth GM built
steering box being installed in my truck.

Thanks Max for clarifying that. The first thing I did today was to
take a look in the dodge service manual, and sure enough they are
called upper and lower suspension arms.
