New thunking noise during spin cycle how long still work?

Sounds like the noise is bothering your roommate and he/she either wants to to fix it, replace it, or stop using it. Compare your repair costs to those of a new or refurbished device, decide how much your roommate is worth to you, and you will have your logical course of action.

Cause 1

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.

Cause 2

Tub Seal and Bearing Kit

The tub bearing is mounted in the middle of the outer tub. The tub bearing helps to keep the inner tub spinning smoothly. If the washer is noisy during the spin cycle or is leaking from the bottom of the tub near the transmission, the tub seal and bearing are likely defective. 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 the outer tub and bearing at the same time.

Cause 3

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.
