I have a Maytag mav6200ww top load washer. Recently, it has quit agitating and making a roaring striping noise. Although it will still spin and drain if set to the spin cycle. If you reach inside and try to turn the spindle back and forth it makes a grinding noise from under neath the washer. I have checked the belt and and it seems to be intact and spinning freely.

It is your Transmission. Mine did the EXACT same thing just a couple days after your post. If you want some troubleshooting advice, part numbers, where I bought my parts, or advice on disassembly/reassembly, I will be glad to help. The truth is, I already wrote a detailed answer to your problem and before I posted it I read the "Terms of Use" page, and when I went back to the "solutions" page, everything I wrote was gone. So, if you want it, let me know and I will try again.

Its probably you stator plate and rotor. But you need special tools for this repair. There a spring that is under 200 pounds of pressure and if you take the screws off that hold the plate its going to fly into you face if your dont use the special tools to depress the spring. Is it more of a clanking kinda of noise? DOes it olnly happen with heavy loads? Try this out. Fill the washer with water only. and get it into a wash cycle with water only. If there is no noise then put in like a load of towels. A heavy load. Now if you hear the noise now then its for sure you stator plate and rotor..hope this helps, but like i said you need those special tools to do this repair or injury can result from the spring part.
