A lot of screeching noise while tumbling
It took me a lot longer to plan the repair and decide to do it than to do the actual work, knowing what I know now, and having the parts, it would take less than half an hour. As there are no repair manuals available, it took one of these reports to give me the confidence I needed to proceed.
I first found out how to open the front (only two screews on the underneath part of the front cover) and opened it to hear the noise, (just put the cover to one side while still connected to the door switch),,,,, sprayed some WD40 all over the place and the noise went away temporarily (DO NOT DO THIS as the oil will burn off on top of heater unit and smell and smoke). I replaced the roller that the drum sits on (above the heating unit) to the right of the drum and the belt. You need a special tool that fits into the little holes in the ring retainer, I got it at Lowe's ($20 +/-). It is a Channellock plier that opens when you squeeze, you have to change the points (comes with it).
So, here is the squence: remove the front panel, disconnect the swhitch (it took some pulling), set aside; remove front drum assembly (only four screws looking at you) and it comes right out; the Drum is light and comes right out as well, it just sits in a dry channel. The belt will fall off.... take the retainer ring off the roller with the special tool... remove roller and replace with new washers (one on either side) replace the ring retainer (recommend getting new one) with same tool. If you remove the small panel in the back of the washer it is very eassy to replace the belt.... I did replace it although the old one looked almost new .. instructions and a diagram come with the parts you buy here by the way... which they should say... place belt on drum per instructions (solid side down), put belt inside the chanell on drum (it will climb to the correct position by itself) put on drum front cover to hold drum in place, and then sting belt on pulley from the back of the dryer. (diagram comes with belt otherwise look at it before taking off the drum) Replace front panel (after reconnecting switch) and you are off (if you want to test without the front panel you have to touch the switch wires to each other (use tape) and do not do plugged in...
After much anxiety but not that much work the dryer runs great and is as quiet as new.... I took the parts off before ordering by the way.... the order came within three days... I am happy to have PartSelect.com .. Maytag had not clue this model even existed.... Thanks

Dryer making strange thumping noise
Removed back panel of machine which exposed badly worn idler pulley. Have had problem before on another dryer so I was sure what problem was before I started. Removed snap washer and cloth washer and then bad pulley.(It was very worn and wobbly).Cleaned shaft with small piece of emery paper and put two drops of oil on shaft and replaced old pulley with new one.Put back washer and snap washer.Drive belt had slipped away from its proper position so I had to remove the front panel of the dryer to place the belt back and realign it on the drum and around the new pulley and the motor drive shaft. Not really that difficult.....Machine now runs like it's brand new.....

No heat
I watched Steve the repairman on u tube then opened up the front of the dryer and noticed the part in my dryer was a little different than the one on the video. So I called in and I was reassured it was what I wanted. When I got the replacement part and before I removed the old part I took pictures of the wiring noticing the wires where changed from left to right I had to make up one of the 12 gauge wires and connectors with parts from the hardware store and the new part was shorter than the old part, but the machine all ready had screw holes where I needed them. I looked at my photos and wired the new part the same way I took the wires off the old part and put it back together and it works like new! saved money! the local guy is $150 to show up and start the clock. I also fixed the blower,EASY!

The motor belt was broken, lint filter torn and light bulb burnt
After watching the short video on belt repair, I put the belt on and ran it through the idle wheel from the small opening on the back of the dryer. I made sure that the felt around the tumbler was not folded and that the tumbler was free to spin.I also thoroughly vacuumed the entire interior of the dryer and the lint filter channel

replace idler pully and belt
After viewing repair video I used those instructions, after removing drum place new belt on drum, I used scotch tape to hold belt in place, tape belt with 2 inch strip about every foot around drum, leave extra belt that connects to drive motor folded down and taped to drum. After installing drum connect belt to drive motor and roll drum to remove tape. This will keep belt from sliding out of place on drum while installing.

Part access but easy solution!
Overall, the repair was pretty easy. I'm a 52 year old woman who has never done drier repair. I replaced both front glides, both drum support roller wheels, the idler pulley wheel and the tumbler and motor belt. Including vacuuming out the inside of dryer and washing down the inside and outside of dryer with cleaning wipes, the whole project took me 2 hours. (if done individually, time would have been 20-30 minutes). You must have correct tools, so I did have to purchase two tools that I didn't have. My only suggestion in replacing the idler pulley wheel and the tumbler/motor belt would be to take the small access panel off the back of the dryer for easier access to the parts.

Motor Bearings Were Bad Causing A High Pitch Squeak / Squealing Noise When Dryer Was Running
First, it is IMPERATIVE that the dryer is unplugged from the wall or the appropriate breaker is turned off to prevent electrocution!!! The front of the dryer is removed by removing the two screws at the bottom of the front with a Phillips head screwdriver. Next, remove the door wiring from the wiring clamp and set front / door of dryer to the side. Next, remove the bulk head by removing four nuts from the sides with the appropriate nutdriver. The drum belt will have to be disconnected from the motor pulley by lifting the spring of the pulley to release belt tension. This can be done from the front or back access panel of the dryer. The back access panel gives you a better view of the motor pulley and attached belt. After removal of the belt from the motor pulley, the drum of the dryer can be removed. Next, remove the heat shield at the front of the dryer. It is held on with two nuts and can be removed using the appropriate nut driver. Next, remove the blower wheel housing cover using the appropriate nut driver. The blower wheel will be next. It can be removed by using a pair of pliers to remove the circular clamp. A pair of snap-ring pliers will also be need to remove the snap-ring also holding the wheel in place on the motor axle. After the blower wheel is removed from its housing, the housing will need to be removed. The housing is again held in place by several nuts and the appropriate nut driver will be needed to remove them. Next, take all wiring loose from the motor. It would be a good idea to photograph or note how and what wires were attached in specific locations on the wiring harness. The new motor may be different when it comes to wiring and will be accompanied by a wiring diagram and the needed connection ends for the wiring. If it is a different wiring layout, as was my motor that I ordered from this site, a set of wiring strippers / pliers will be needed to cut, strip, and crimp the new connectors. After wiring has been removed from the motor, remove the motor by removing two nuts with the appropriate nut driver from the bottom of the motor mount. The motor, mount, and pulley will then all come out as one piece. The motor will then need to be removed from the mount. This can be accomplished by using a flat head screwdriver and a hammer. Place the flat end of the screwdriver into the raised edge of the motor mount clamp and pull away from the locking bracket. If needed, use a hammer to give that extra tap to the end of the screwdriver to remove the clamps. After the motor is removed from the mount, an Allen wrench will need to be utilized to take the belt glide / seat off of the motor axle. You will also need the snap-ring pliers again to remove a snap ring from this axle as well. Clean the motor mount and dry thoroughly. Grease the pulley housing where it contacts the motor mount for smooth gliding against the mount. It is important that you use a NON-FLAMMABLE grease. This is the end of the "tear-down" phase. Now is a good time to vaccum and clean the inside of the dryer cabinet. This will help insure that excess lint and fuzz is removed to prevent an accidental dyer fire. Next, place the new motor back into the motor mount in reverse order. Make sure the belt glide / seat from the motor axle aligns with the belt marks on the pulley. Reassemble the dryer in reverse order, making sure to follow the wiring diagram provided with your new motor. Also you need to insure that the motor is turned at a 45 degree angle to allow the dryer drum to pass the motor without striking it. After reassembly, plug in the dryer and attempt to start. If your dryer does not start, troubleshoot the wiring first. Wiring was the most difficult part of this repair and working in the tight space provided was a trick. Also look up a video of the repair! This helped me tremendously. Videos can be found on this site or at YouTube.com.

Squeaky when in use, after replacing the drum pads.
I followed the videos provided, the only think I would added is cleaning the riding surface of the drum. In my case the drum had gunk on it from the old pads, witch got on the new pads causing it to continued to make noise.

It would be wise to also get the felt and belt, to replace them all the first time.

Drum would not turn, drive motor humming loudly and unable to turn drum/blower wheel
The repair video is terrific and many others here have thoroughly described the steps involved to replace the drive motor.

The biggest hurdle for me was that the motor came with a new switch that required a different wiring configuration. No wiring diagram was included. Several others had posted questions about wiring in the Q&A and unfortunately PartSelect kept copy/pasting the same confusing and incomplete answer over and over:

"The Yellow goes to T6, Red to T5 Black to T2, blue to T1 and the white you will remove the blue jumper lead between the switch terminal 4 and 1/4" protector tab, connect the grey harness lead to the 1/4" protector tab."

Reading that doesn't tell me what to do with the white wire, doesn't address that my blue and white wires were crimped into the same connector from the factory, doesn't address that I had 2 black wires crimped into the same connector from the factory, and doesn't address a factory ground wire that connected the frame of the OEM motor to the bracket that the motor sits in.

With all the other excellent info supplied by PartSelect, this was surprising and frustrating. The sales dept ignored an emailed question from me, and the Q&A section didn't allow me to post a question.

Searching the internet, I found a wiring diagram on aceappliancesd dot com that addressed my dryer's OEM wiring configuration. Here's what I ended up with:

TI - Blue and white, crimped together into a single connector
T2 - Black & black, crimped together into a single connector (the wiring diagram I found said this should be black & brown, but they both look black to me)
T5 - Red
T6 - Yellow
1/4" Thermal protector tab - Grey (from the harness)

The new motor switch had a grounding tab with nothing connected to it. I removed the screw holding that tab into the switch and connected the (also grey) OEM short ground wire from the motor frame to the mounting bracket.

I had to cut 2 of the pieces of tape holding the OEM wiring harness together in order to get enough slack for all the connections to reach. If you do this too, make sure all the wires are still clear of the moving parts and the hot bits. You may need to retape the wires together at a different location to keep things tidy.

I also laid the belt over the drum and put 2 pieces of tape over it to hold it in place while I got the drum positioned, then I reached through the back access panel to loop the belt around the motor pulley and idler. Once that's done, just reach over the top of the drum and peel the tape off. I found that much easier than trying to loop the belt by reaching through and past the drum.

Belt broke...drum would not turn but there was heat.
Removed front cover.removed 4 screws holding drum in place. Cleaned out lint from everywhere. Placed new belt over drum looping it over idler arm & motor pulley. Pushed drum back ; rotated drum to see that belt was engaged. Put front drum bracket in place. Put front panel in place with 2 screws at the bottom. Tested motor & rotation of drum; then checked heat. All worked fine. Took 1 hr. but most time spent cleaning lint.
