Through basic troubleshooting, discovered the motor had seized up. Since the unit was about 10 years old and it had to be disassembled for replacement, the decision was made to replace "likely to fail mechanical components including motor, belt, both rear drum rollers/shafts, idler arm pulley/assembly/wheel, associated washers, snap rings and both front glides. Reviewed the PartSelect website and drawings, ordered the parts and they delivered on time. Buy the correct sized snap rings at a local hardware, they're much less expensive. Also once inside your dryer, you'll likely find alot of lint to vacuum out...have fun.
I went online and Googled several resources that showed how to remove the front dryer panels, as well as PartSelect repair stories. From that point on, I took photos as I was disassembling so I would know how to put it back together. Utilize pictures or whatever system you prefer to keep track of taking something apart and putting it back together.
Remove the dryer door, then the front panel Disconnect wires to the light, dryness sensor and door switch. Note belt and pulley configuration that is near the motor-this will help you later when reinstalling the belt. Also note if the ribbed side or the flat side of the belt is against the outer drum wall. Remove the door shroud.
Slip the belt off the idler pulley wheel. Remove front drum support, then dryer drum Note which end of the dryer drum is the front and the orientation of the glides on the drum support. Discard old belt. Drill out and remove the old front glide supports, then install/rivet the new glides.
Remove both old rear drum rollers/shafts, washers, etc. The rear drum roller shafts are secured to a back bracket by a hex nut....feel around you'll figure it out. Replace new roller shafts. Lightly grease using a high quality silicon grease, then replace new washers, roller, snap ring, etc
Carefully unplug wiring harness on motor, there are fragile clips on each end. Don't forget a separate ground wire from the harness is attached to the motor mount bracket. Carefully release tension on the idler arm spring. Using the correct size nut driver, remove three screws (on this model) then take out the motor/idler arm assembly. Remove the old idler arm/pulley assembly. Remove the motor mount clips on each end of the mount (I used a wide blade screwdriver). Remove and replace the motor. Motor configurations changed after Whirlpool bought Maytag, so orient it correctly insuring mounting gasket "nubs" on each end of the motor correspond to the cutouts on the motor mount. Reinstall the motor mount clips. Replace the new idler arm assembly/pulley wheel; grease moving parts with high quality wheel bearing grease. Replace motor/mount bracket assembly back into the dryer. Replace ground wire to motor mount bracket and plug wiring harness back in. Reinstall idler arm spring.
Place belt back on the dryer drum and move into place on rear rollers. Reinstall front drum support. Dryer drum should turn relatively easy. Insure belt is oriented on the drum correctly before connecting belt to motor shaft end and idler arm wheel pulley (the picture you took comes in handy here).
Reinstall the rest of the parts in reverse.

Parts were on my doorstep in two days. The dryer is like brand new. I could do this job again in less than an hour. This was money and time well spent.

2) Pulled the front panel down and off
3) I checked the belt to see if it was broken and it wasn't
4) I tried to turn the drier barrel manually to see if I can move the belt... it didn't move. Not knowing if there was just too much resistance, I tested the drier while looking at the motor and motor pulley as it ran.
5) I noticed that the motor pinion rotated, but the belt was slipping against it... that's why it smelled. The rubber was burning
6) Then I found that the idler pulley had stopped rotating, and the belt actually cut a channel into part of the plastic... That's when I realized that I had to replace at least the idler pulley.
7) Not knowing whether the bushing and other parts were going to be salvageable, I ordered parts for the whole assembly... but I wasn't sure how to best approach the repair...
8) Then I found partselect.com, and they had both diagrams of the assembly, all the parts easy to order, and best of all, a video of someone actually going through this repair! I was dumbfounded! :)
9) For swapping the parts I just watched the video on how to pull out the drier barrel... the only difference is that I didn't see a need to unplug the cables from the front top panel before removing the drier tumbler. (Obviously the power was turned off :P)
10) when I removed the barrel, I swapped the whole idler pulley assembly, just keeping the original spring.
11) Put everything back together, and it ran like a champ!
The video helped me save a lot of time though... it showed me how the whole thing is most easily serviced and made the repair a breeze!

I took some advise from another story saying to get the whole idler arm, shaft and pulley assembly. It might have cost me a few bucks more, but I did not want to run into the same problem he did (the pulley bearing was fused to the shaft). It took me about 20 minutes to take apart the dryer, install the part, and put it back together. If you are pretty good with fixing things, you should have no problem doing this repair.

I replaced both rollers, the idler pulley, and put on a new belt after giving the dryer a thorough cleaning.
It was a 100% success and fixed the problem making the dryer work and sound like brand new again.
