Maytag Atlantis MAV7501EWW 10 yrs 6 mos old. Intermittent metal grinding noise during wash and spin cycles. With washer front removed it is still hard to say if the noise is from the pump or tranny. No leaks, rust or grease splatter. With belt removed pump, motor and tranny pulleys all turn both ways by hand with no noise. Only the motor pulley will free wheel though. Ran spin cycle without clothes / water and it made no noise. If tranny problem not worth repair. If bearing problem maybe the same. How can I determine for sure if pump or tranny / bearing issue?
Pump or bearing problem?

Most likely suspects are early pump or thrust bearing failure. Can be difficult to tell until the symptoms become more pronounced.
If drain pump is the problem, washer will continue to do all cycles normally but the noise will become constant. Drain pump Part number: AP4373022
If the thrust bearing is the problem, eventually the unit will start spinning sluggishly or not at all. Thrust bearing Part number: AP4009132

Thanks for the info. After a couple more loads sounded more like pump than tranny / tub area so replaced water pump and all is quiet!
Now that we know it is nota washer life ending tranny issue and we will be keeping the washer for hopefully years to come I need to replace the snubber ring. Lots of white shavings and some vibration. Since I will have the tub out to replace the snubber ring is it practical to change thrust bearing at this time if it is also a common problem?

Don't mess with replacing the thrust bearing until/unless you have to because it's enough of a PITA job on its own.
The snubber, OTOH, is pretty easy and inexpensive to replace: Part number: AP4024496
