dryer rotation noise

What I call the idler pulley went out on our dryer so I decided to replace it. While I had the dryer apart I replaced the drum rollers also. When I put everything back together the front of the drum now rubs on the blower housing and it makes a thumping noise. I didn’t see any adjustment to raise up the drum.

When I was taking apart the dryer in order to remove the drum I had to loosen up the right front lower drum glide, but again I didn’t see any adjustment that would allow me to raise up the drum in this area.

Please help the wife is wanting me to fix ASAP.
