Opened the top of the dryer and removed the front two screws, lifting the front door up and away from the dryer, placing my arm thru the bottom of the dryer. Pulling back on the belt wheel to remove the tension in the drum belt, probably the most difficult thing in the whole job. Lifting the drum slightly and pulling it toward the front easy, while holding unto the belt.
It is not that hard, but make sure you check the support wheels on the back bulkhead to insure they are in good shape, do not oil. Also make sure the drum is not damaged at all, and that it is not out of shape, just repeat the removal backward and your done. Might take about a half-hour if you clean out the dryer vents and inside the bulkhead of the dryer, recommended. The drums are no longer available, so if the drum is damaged, good luck, you might find a used one, but they are expensive online. Not difficult.
