Dryer making squeaking noise when operating

First I had to remove the top by taking out the two screws inside the door. Then I removed the front by taking out the two screws holding it from the inside. I needed to remove the drum and to the the belt off, I removed the left side. It has several screws down the back, two on the bottom and two in the front. I removed the belt and drum. I took out the old sleeve bearing. Part of it was broken off into the hole it goes into. I then had to remove the plate that holds the heating element. Once that was done, I put the new bearing on and replaced the drum slides on the from section. Then I reversed the process to reassemble. Not too bad.
