X axis calibration

Can someone please point me in the correct direction to fix this issue see pictures. Its probably easy I just dont want to mess it up. The opposite side of the stepper. The belt isnt in the center I think this is what is causing vibration on very fast movement. Everything else is tight my Y axis never moves from center. I’ve moved the pully on the stepper motor but it doesnt help. Thanks for any advice.

Ok I had some time I found this. It said to adjust as neccessary I am guessing I’m adjusting the belt in the clamp? To get it straight.

This post can be deleted figured it out. Just had to mess with the positioning of the belt on the extruder bracket.
