Loud sqeeking noise while running

Removed the two screws holding the top. Popped the top. Removed the door wires. Removed 2 screws at the top of the front panel. And removed 2 screws from the bottom of the front panel. Pulled the front forward dropping the drum. Relaeased the tension of the belt pulley. Pulled the drum straight out. Removed the right roller. It was worn out. Placed the retaining clips inner and outer. Lubricated both drum supports with lithium grease. Replaced the new belt with the belt tensioner. Reassembled drum, front panel and top. Dryer runs like a Top now. Careful of the sheet metal edges very sharp.....
