Would have cost $250+ to have a service man out.  Bought these for around $50 and it was not hard to replace in the washer after watching a couple youtube's.  Until these, EVERY load would get the THUMP THUMP THUMP, then Uneven Load and washer stop.  Since replacing (about 3 months now), not a single THUMP THUMP THUMP or UL.
