Allegedly 'heavy-duty' washer had been having 'wigwag' issues on 'heavier' loads [like any towels at all in mix]. Is level. Would start after redistributing the load. Today it 'wigwagged', then wouldn't restart even after heavy items removed. Now it just makes a low buzzing sound, like the wigwag alarm only much softer-- like a solenoid is making contact but no follow-through from the motor or tranny.
Is this a basket drive/brake issue, snubber problem, or something easier/less expensive to diagnose/repair?
P.S. have already bypassed lid switch, since that was a previously-failed part.

this is an update, since i 'solved' the problem [temporarily, anyway]. turns out this belt-drive whirlpool model has a 3-point ball/socket/rod suspension system for the tub; the lower balls were very compressed, so i switched them with the top sets, and lubricated all the balls/sockets with white lithium grease. spin cycle then ran fine. only problem--whirlpool no longer makes the rubber balls, so can't replace the old ones--a shame because this 25 year old washer still runs strong.
