Dryer squeaking really badly

I opened the dryer from the front by pushing in on the two clips just under the top. I then had to remove two screws on each side and took the front panel off. I reached around underneath on the right side to slip the belt off the pulley. I pulled the drum out and then I could see the roller that was squeaking (the left one). The wheel had sheared some of the support off and that was the cause of the squeak.

I took the locking ring off and removed the wheel and support. I put the new support in, attached it, and then the wheel, washer and lock ring. I used pliers to push the lock ring onto the support.

Then I put the drum back in making sure it was in all the way (it fits snugly between the wheel and the back of the dryer). The belt is a little tricky to get back on. I put it around the drum and then reached underneath and behind again. The pulley is on a spring, so you have to pull it up and put the belt on all one-handed and blind. Once that was on, I gave it a few turns to make sure everything was working again.

It is quiet as can be now!
