Creaking noise, 2001 Dakota

I've posted about this before; I had the dealer do the tsb that resets 
the steering wheel, but the sound is still there.

I've a 2001 Dodge Dakota SLT 4x4.

There's a creaking noise when I turn the steering wheel (seems worse 
left), or when I go over a bumpy road.  Seems to be in the front end 
somewhere, but I'm not sure where.

It doesn't seem to be anything horribly dangerous - we just got back 
from a 3,000 mile journey across the Australian Outback and the Great 
Ocean Road, through a variety of climates from really-hot-and-dry to 
raining-and-cool (we experienced temperatures ranging from about 
52f-104f), and nothing fell off the truck.

Still worried something might though <g>. It could be old truck 
syndrome, but I want to make sure.
