Loud noise during wash cycle

Cause 1

Pulley

The drive pulley might be worn out, cracked, loose or bent. Remove the drive pulley and inspect it carefully. If the drive pulley is damaged or defective, replace it.

Cause 2

Drive Motor

The drive motor bearings might be worn out. Washer motors are normally very quiet during operation. To determine if the washer motor is defective, remove the drive belt from the washer and then run the motor. If the motor is still loud, this indicates that the drive motor is defective and needs to be replaced.

After listening to that it sounds like a bearing to me.

Cause 1

Rear Drum with Bearing

The rear drum has a bearing or bearings in it to keep the inner tub spinning smoothly. If the tub bearing system is defective the washer can become very noisy. On some machines bearings are sold separately from the rear drum, however we recommend replacing both the outer drum and bearing as an assembly if the manufacturer offers the components together because removing and pressing in the new bearing can be exceptionally difficult. Be aware that replacing the outer tub and bearing is also not easy and can be very costly.

Cause 2

Bearing

The tub bearing is mounted in the middle of the outer tub. The tub bearing helps to keep the inner tub spinning smoothly. Replacing the tub bearing is a very involved repair and will require disassembling most of the washer. If the tub bearing is defective, we recommend replacing both the outer tub and bearing.

Cause 3

Tub Bearing

The tub bearing is mounted in the middle of the outer tub. The tub bearing helps to keep the inner tub spinning smoothly. Replacing the tub bearing is a very involved repair and will require disassembling most of the washer. If the tub bearing is defective, we recommend replacing both the outer tub and bearing as an assembly if the manufacturer offers the components together.
