The washer is making a terrible racquet. The belt seems to be rubbing; black stuff all over the place. Can I adjust the belt?

Belt won't make a metallic sound. A pulley can if it has a bad bearing or is rubbing against metal. Probably only two screws holding front panel on so have a look inside. On my 1996 Maytag moving the pump after loosening 3 screws adjusts both belts.

The belt does not need to be replaced more than likely. The problem is probably because that adjustment bolt is stripped out causing it loosen and keeping it over on that side. ProForm sells star washers that help them stay steady and not slip out. I would call them and ask for a couple of star washers and a new adjustment bolt for that left side.

if you have gotten that far your good
now try to look at the motor it sounds like your belt might be a lil off track on the mortor shaft
there is a adjustment srew on the top left of the motro its hidden under things but its there
you can looses this and swing the motor
make sure you have it lined up on the motor shaft and it should stay aligned on the pully

what sort of noise is it a rubbing noise?

Check the strut assembly. also a bad bearing can make banging noise.

I have a different suggestion based on my washer's similar problem. If the black stuff is powdery and localized at the back of the unit, more than likely the culprit is the drum pulley itself is warped, causing the belt to chafe against the drum. The black powder is rubber residue from the scraping of belt on plastic. No need to replace unit. New belt and new pulley run about $70 each.

ok " sounds like motor belts need replaceing, that smell is the loose belt rubbing against the motor pully.

Try some anti-sqeek stuff on the belt, or just rub some soap on the belt.
