I thought the problem was the lower unit so I ordered and installed it, but that was not the problem. It turns out that the Line Trimmer Spool was the culprit. The center hole in it was reamed larger and therefore it wobbled. The design of this trimmer should include a lock washer and not just a nut. The trimmer itself has been excellent. Love the string loading mechanism.
