Product review (5 stars): OEM dampening straps
If you've had your GE washer for a few years, your original straps have dried out and no longer provide dampening.  That's why your tub is banging so loudly.  This company sells these at the best price I've seen, they're OEM and very easy to install.  Took me all of 15 minutes with a 1/4" and 5/16" magnetic socket screw driver tip installed in my battery powered screwdriver.

Once installed, the washer is as quiet as when new.  Worth every cent.  Get these if your washer has become noisy.
