I think your a bit off on the model number you posted. Maybe you meant model number GCAM2792LQ0
How old is the washer?
You probably already did this but make sure the washer is level and the front legs are locked in place.
Also make sure all the springs are still in place.
If the washer has any age on it and it's been fun up to this point then I would replace the skate plate part # 3946509
It will also come with all new pads.
I would also replace the three main spring, part # 63907
