I have a couple of thoughts. If I remember correctly, the idler
arm on this model has slotted holes in the frame where it bolts
up. It's a common mistake to not re-align the idler arm properly
so that the steering geometry of the center link and the rest
of the linkage is horizontal. If this is not correct, you will get
that "bump" steer that you are describing. The other item,
drifting to the right....may be related to the idler arm problem,
but if not, the alignment tech needs to "tweak" the caster so
that it's slightly higher on the right side then the left. I don't know
what your alignment figures are....did you get a printout after
the alignment was done? If so, post the numbers here, and maybe
we can see if there is something that could be changed.
Since caster changes do not wear tires....it's by far the
more effective angle to change on a double wishbone front
suspension when dealing with a pull. And on an S-10 truck,
it's very simple to change as you have eccentric bolts in the
upper control arms to change the caster/camber angles.

I would add that not all alignment shops are equal.
My new Astro van pulled to the right, and no tire swap would
fix it. I took it to Les Schwab and paid $25 or so for an alignment
that took 45 minutes. The van pulled worse than before.
I then took it to a place in Vegas that was known for front end work
and still used the old Bear alignment system. They spent almost 3 hours
on it and charged me only $60. It now drives very nearly perfect.
I think the cheap shops may have guys that don't fully understand the
numbers the computers spit out either.

Thanks for the reply. I took my truck to Hoover Wheel Alignment. Thats
pretty much all they do. The alignment cost me $45 and then for the torsion
bar and idler arm adjustment cost me another $15. They spent at least an
hour and a half with it. I'll call them up and see what they say. I've heard
something about a 4 wheel alignment, can that be done on my truck?
Thanks

Thanks for the reply, I read about the idler arm adjustment and asked them
to look at that also, sorry I didn't say that. They didn't give me a print
out of the number just an overall sheet stating "alignment". I'll call them
about the caster and see what they say.
Thanks

Just remember this...next time you get an alignment....insist on a
printout showing "before" and "after" alignment readings. Any
competent alignment shop should provide you with this type of
printout. Otherwise, you have no clue as to what they actually
did. Even if "you" don't understand the readout.....someone will.
