I started by trying with a butter knife to push the clips that I had seen on older dryers and washing machines when I saw it had 2 screws holding the top to the front. So I opened the door and saw the 2 screws that held the top to the front panel. Removed those and lifted the top panel a few inches and slid a broom handle in to hold the top panel up. Found 2 screws holding the front to the sides and removed those. the front then just lifted out away from the bottom and sides. I unplugged the three wires going to the door switch and light. Vacuumed all the plastic shavings up and replaced the drum front support bearing, the 4 bearing slides and the trap duct assembly all which just snap in. Plugged the three wires back onto their terminals and put the 4 screws back in that had been removed and dried a load of clothes. Nice and quiet again. Short story: remove 4 #2 phillips screws, snap old parts out, Snap new parts in and assemble.
