Based upon my recent experience, I recommend that you replace the idler arm bushings first, then the tie rods / steering damper and drag rod. If you still have a few dollars, take a look at the upper control arms. If your budget holds, and your inner demon needs a workout, replace the damper rod bushings. Then go to the MB dealership and get your ride aligned.

But thats based upon exactly 1 time to this particular 1982 MB 300SD rodeo!
