Check the suspension, all of it. It should be almost, if not completely worn out by 180k. This includes the shocks, springs (for sag,) and all bushings (for cracking or setting.)

Align it, it's probably out. Have the tires balanced, or replaced if they show wear or age damage.

Check ignition timing just because, and replace the fuel filter, plugs, cap/rotor, and wires if you are uncertain of the age... an oil change and trans fluid change goes without saying.
