Suspension bushings. At the age of the vehicle, the inner tie rod
bushings are almost guaranteed to need replacement. You can either
spend a little bit of money at NAPA/Carquest/whoever for

Or spend a fortune on a special service tool and have a nightmare trying
to install the OEM replacement part. I did the latter once on my wife's
2000 Intrepid, and then learned about the former and did that the second
time.

(note, while I'll predict without looking at the vehicle that you'll
need those bushings, there's a bunch of other bushings that may well
need replacement).
