Have a Whirlpool washer model no.GCAM2792LO0 that works except when it starts to spin,then it woubles and shakes and makes a loud banging noise.I have taken the case off of the washer and when it goes into spin I can see the suspension plate banging on the base assembly.The little pads on the suspension plate and on the base do not seem to line up,they are off and when the washer spins it is metal to metal making the banging sound.Also the pads do not seem to be worn out.What would cause this condition?Do I have to replace the suspension plate and the base assembly?Thank you for your time.
