Product review (5 stars): A little more work than I had planned on, but worth the effort.
The bearings are high quality and were easy to change once the drum was out of the washing machine. Getting the drum out was not a pleasant experience as I had to do it in a cramped upstairs laundry room. Getting the drum back in was a little easier. To knock the bearings out, I used a 12" piece of rebar that I purchased at Home Depot for $1.00. Also, if you're going to go to the trouble of replacing the bearings, do yourself a favor and spend $35.00 on a belt and new shock absorbers.
