Product review (5 stars): Save a lot of money if you can use some basic hand tools
These bearings saved us over $300 over a new tub assembly on a Frigidaire FTF530FS1, or more on a new washer.  If your clean clothes end up having brown spots on them in a pattern, you probably need these bearings.  Frigidaire or parts distributors don't seem to sell just the bearings - only the whole rear assembly for a lot of money and it's almost cheaper to buy a new washer.

Installation was pretty straightforward and there are a lot of youtube videos with step by step instructions.  I recommend following the videos, mostly so you don't forget to unhook something and end up breaking off some pricey connector.

Take your time pounding out the old bearings and be sure to only hit the outer races on the new bearings when driving them in.  I used a metal drift when I started, but found a piece of 2x4 to be a lot easier.

The seller I used was "Jet Ski Parts" and they shipped fast, which my wife appreciated since the washer was in pieces.

My only advice is to try to find a new gasket that goes in the joint between the two tub halves.  I used RTV, but only because I didn't order one, not realizing I might need it.
