Z wobble or some sort of problem with gantry?

Not sure what is going on, but I am having z wobble/banding on VCore 3.1. I've tried doing a bunch of different stuff to the z axis, checking everything and making sure it is straight and the lead screws are straight and seated properly and there's no binding. I am still getting z banding but it seems to be mostly only on the Y axis movement.

The pictures here are from the left and right side, which would be the y axis and the gantry moving. It isn't really there for the X axis though, which I'll add the pictures for the X axis below.

I've tried fixing the gantry, I've untightened and reset the mounting points to straighten it to see if that was the problem but there wasn't any change really. From the shaper graph, the "y" green line is the x axis which causes the second peak. I don't really know what I should be looking for, everything is tightened, the belts are all moving correctly on the pulleys. I'm at a loss, I'm not sure if I should be looking at Z or Y, or even what anymore.
