I went on you tube, searched the problem, watched a couple of videos, decided to was the tub springs, but the snubber and belt should be replaced to. The AppliancePartsPros video was well made, had a parts order link. The prices looked fair, and a parts check against my model number ( and a were-to-look diagram) made it easy.
The parts arrived quickly, and I followed their snubber replacement video step by step, but put my new parts back. ( One spring position was too awkward for me to do, but I used a trick from another youtube video and pre-stretched the spring by slipping washers in each 1/2 turn of the spring coil.
My wife bragged to her bridge club, and it runs like new.
