2420 grinding noise that is not the fuser?

I have been working on this machine for days. Original problem was loose tray 2 pickup shaft. I reattached that and then tray 2 wouldn't pull paper. I got it to pull paper but it makes grinding noise that only occurs when printing from tray 2, not the bypass tray. It only occurs when passing paper. If I trigger the sensor without tray 2 installed the roller turns with no noise. Thanks in advance.

It has to be something other than the p/u gears or fuser gears because I can trigger the sensor and the tray 2 roller turns without the noise and no noise printing from tray 1.

Now IDK I think it might be the pick up or feed gears.

I got it, The tray 2 p/u roller had to be flipped. That's a new one on me.
