how can i fix my GE model WJSR2080 washer?

My GE model WJSR2080 washer is really loud when it spins. It doesn't squeal, just the spinning noise is just louder than it has been. It started a few months ago. It was overloaded, it is a self leveling machine but I was washing bed pillows in it and there were too many and the machine could not get itself leveled. After that the spin cycle (the normal noise) was just louder. Normally with the door closed to the laundry room you couldn't hear it, but now it can be heard throughout the house.
