Product review (1 stars): Don't do it here's why...
. I spent approximately 4 hrs or more breaking down the unit, replaced the bearings with no real issue. They were in need of replacement, the problem however is not just with the bearings, its the inner drum and shaft/spider that's also the issue, so I'm told by some GE appliance guys. I'm guessing as the bearings wear and the inner drum starts to become more and more imbalanced, it "bends" at the connection point to the shaft (made of pot metal), causing increased runout on the drum in respect to the shaft. The plastic drum that holds the bearings could also be out of spec due to this and is probably why GE replaces only the drum as a whole. So after replacing the drum bearings( which are fine by the way) and reinstalling everything, the unit does not shake as much, however as speed is increased on the spin cycle, the machine detects imbalance and slows down and restarts the clock.  Don't waste your time and money as others pointed out, replace it with a top loading unit. My model is a GFWR2700H0WW. Now with that said, later models apparently have a different spider in which case replacing the bearings on your model might work out just fine.
