Product review (5 stars): Cures grumbling spin cycle
These completely saved the day for our 15 yr old washer.  It's a fair piece of work to get the drum assembly out of the washer shell, but this is where the problem was.  Inner seal goes bad which leads to inner bearing failure.  You'll also need the outer drum seal to re-assemble everything.  We did bearings, seal, speed control board, and belt.  Less than $300. total for essentially a brand new old stock washer.  Beats the $1,500. for new paint and bells & whistles.
