Product review (1 stars): although there is no reason to believe that replacing the tub will last any better. Turns out that Whirlpool makes some Kenmore
After 5 years and lots of loads the washer now makes a screeching/grinding noise during the spin cycle.  A quick search of the web shows that this means that the tub bearing needs to be replaced.  The cost of the parts is $100 + another $100 for a special tool needed to press the bearings.  Or, you can replace the whole tub which costs $300.  I'm afraid that if I just replace the bearings, I'll have the same problem in a couple of years, although there is no reason to believe that replacing the tub will last any better.  Turns out that Whirlpool makes some Kenmore and all Whirlpool and Maytag washers which have the exact same problem.  They offer the illusion of choice while designing in obsolescence.
