I recently replaced my bearings and seal for about $60. I could have bought the bearing cheaper online but I was in a hurry. If you do a search online there are several blogs about replacing these bearings. Here is a link for a service manual for $ 18 http://www.repairclinic.com/SSPartDetail.aspx?PartID=659075&PPStack=1
You pretty much have to disassemble the washer but it is not really that difficult depending on your mechanical experience. The manual should lay it all out for you. There are 2 notes on these frigidare washers: Sometimes the spider arms on the inner drum break and you will have to buy the complete inner drum assembly. I have heard they are warranted for 25 years, but they most likely will not warranty them if the owner does the work. Also, Frigidare does not list the bearings seperately, but you can buy the bearings from a bearing supply house, online or in your town. The bearing numbers are on the side of the old bearings when you remove them.
NOTE- The bearings that came out of mine were 6306-2Z and 6307-2Z (shielded) I replaced mine with 6306-2RS and 6307-2RS (sealed). The significance is that the shielded bearings offer minimal protection from water where the sealed bearings are built to seal out water/contaminants if you new seal ever fails. The seal I used was a CR15939 rubber coated seal.
If you need any other information, let me know
Hope this helps
