Product review (5 stars): Cheaper Than the Alternative
One of the tub bearings went out in my front loading LG steam washer and a local appliance company quoted me almost $700 for the repair.  I decided to do the repair myself had to choose between whether I was going to piecemeal the bearings and seal or go with a new tub assembly, which has the bearings and seals already installed.

I set aside a Saturday morning to do the repair and my brother-in-law and I, with the help of a YouTube video had the job done within a few hours.  We went slowly and methodically and took time clean up of the existing components which we re-used.  I also made sure to pack plenty of waterproof grease into the new seal.  My LG runs just as good as new and I should get at least another eight years of use out of it.

Make sure if you decide to do this on your own, take photos before you disassemble things and be careful with removing electrical connectors so you don't break retaining clips.  I would also recommend buying a new tub seal/gasket.
