My x-axis belt is wobbly, and causing z banding..

it is wobbling from side to side as shown in the video here: IMG_4196

and picture below is the z banding. When I move the hot end to the center, the belts from the right side of the hot end looks parallel while the left side when jutting the x -axis back and forth, shows the wobbly nature of the left pulley.. How do I fix this, I've tried to adjust the 2 tension screws but it slightly still skews? Also the 2nd pic shows some residue underneath the pulley.. It looks like the screw that centers the pulley is rubbing down the screw.
