Another out of balance problem

The spin cycle wobbles alot even when there are no clothes inside. Problem just surfaced this morning.

All 3 main springs look good. Should I increase the tension on these?

There are a few yellowish-white waxy bits at the bottom of the unit, but less than the size of a pea total (if you mushed them together) I don’t believe this is enough evidence of a snubber problem.

Not sure what else to look for.
(I have a Whirlpool manual, but couldn’t find the manual for this online)

Thanks for your help.
