Noise during spin for whirlpool

Right after the machine drains the water and starts the spin cycle, I get a rubbing sound in conjunction with a high squeal sound. As the tub spins faster the rubbing sound slows up to nothing and when that happens the squeal sound goes away. This last for @ 20 seconds. otherwise the washer is working fine. Any suggestions

Could be something caught between the inner basket and outer tub or something in the drain pump.
