Re: drum rubbing on inside walls
Go into the back of the dryer. Remove access to back and you will see the drum. Chances are your motor that turns the drum is loose or the shaft or spindle that the dryer spins on is loose from its bracket. Tighten all that up and it should be fine.

Ken, Don't know if this will be of any help or not, as I've never seen a dryer drum with the felt seal on the front. All of the machines I've repaired, (and that's a bunch), had the felt seal on the rear of the drum, with the front being supported by the configuration of the front panel where the door is located. Mostly the front of the drums were supported by small strips of teflon, or cork, as slides, but that's it. Never had one with felt in front. Is it possible the drum is in backwards?
You did get the right replacement bearing assembly; did you also replace the bearing retainer and ground strap to the gas diffuser?
I'm sure you followed the repair procedures as described in this video http://youtu.be/MPXu-Ya8CBY And if you did double check everything I suggested- then the next thing I would have to ask, is the noise you are hearing only happening when the dryer is full of clothes or does it also occur when the drum is empty?
If the noise occurs only when the dryer has clothes in it, you may be overloading the dryer.
If the dryer is making the noise whether the drum is loaded or unloaded, then the next logical step is to check for level.
Place a carpenter's level on top of the dryer; check it side to side; and front to back; adjust the leveling legs if necessary.
From my experience, a scraping sound could be caused by metal or hard plastic objects getting caught between the cabinet and front seal of the drum. And you already had it apart to replace the front bearing and slides; and I'm sure you inspected the diffuser for any damage or being out of round when you installed the rear bearing...at this point, predicated you did replace the bearing retainer and ground strap- the only 3 things you didn't replace is the gas diffuser, the drum, and diffuser- not to suggest that you do :) Please keep me posted. Best regards.
The first thing I would check is to make sure your exhaust line is clear. Most problems with long drying time stem from something slowing down the air flow through the exhaust line. If you have access to an electric leaf blower and you have a long exhaust line, you can use the blower to try and clear out the line. If you get the line clear and you are still having problems you may need to check your thermostats because they could be turning the heater off too soon. If you have moisture sensor on your dryer it could also be turning the heat off too soon if you use dryer sheets. Look for either one or two curved strips of metal either on the back wall of the drum or on the inside front wall of the drum. Take some rubbing alcohol and some cotton balls and rub the metal strips. If the cotton ball turns blue there is a build up on the strip from your dryer sheets. Keep cleaning until it no longer turns blue and then try a load. Hope something I have written will help you.
The rubbing sound is probably due to worn or missing glides around the dryer opening that the drum rides on. These are usually mounted on a felt strip that is glued to the front panel of the dryer. Remove the front panel and you will see this strip. It is easy to replace and comes in a kit with the glue. Make sure you clean the area after removing the old strip so the glue will adhere properly. If this strip and glides are in good shape, I would look at the bearing or rollers at the back of the drum and check clearance around the drum for rubbing. Hope this will fix ya.
i had the same problem.it ended up being the bearing that holds the drum in place.it had worn that bad that the drum was rubbing the bottom of the dryer.the bearing is located on the back of the dryer if the bearing is worn there will be like black dust around the area.this does stain so be carefull
there is a heating element on the back wall and it looks like a spring closer on a screen door it is kinda flimsy and bends and warps as it cools and heats and sometimes it will rub on the drum or the back wall it shorts out and breaks a new coil costs around 80 $ takes a while to string through the ceramic holders you get some replacement holders to replace cracked or damaged ones with new coil. you can buy one pre strung it will cost allot more not an easy task for a first timer.
Your drum may be out of round. The drum belt on the outside of the drum may be rubbing against the cabinet. When the cabinet heats up, the side walls of the cabinet may be bowing inward, thus making contact with the belt on the drum. This would explain why it is intermittant. When the heater turns off, the cabinet cools and the sides bow back out.
The bearing is worn and now the drum support is rubbing against the metal mount. I do not know what type of dryer you have but my web page covers a lot of material. The dryer that is easiest is mentioned here, plus I have pages on your dryer as well. READ MORE
The rythmic rubbing sound you are hearing could be coming from a few sources. It could be drum support rollers that require lubrication, bulkhead screws that have come loose, the drum seal not seated properly, or a silencer plate that has come off the compartment side and is rubbing on the drum.
First, look inside the dryer along the seam where the drum meets the front and rear of the dryer. You should not see any part of the felt drum seal protruding inside the drum. Sometimes the seal starts to come loose or becomes misaligned and sticks through inside the drum. This will cause thumping and excessive noise. If you have anything caught in the drum seal (i.e., a screw, change, etc.) this can also cause excessive noise.
Remove the dryer top panel and start the dryer and watch for anything obvious rubbing on the drum. The top comes off by removing the screws in the rear and sliding the panel back, then up. (CAUTION: DO NOT get your hands around the drum while it is rotating and any of the electrical connections). Look for any vibration from from the rear bulkhead (this is the back wall of the dryer where the drum rides against). Sometimes the screws holding the bulkhead to the cabinet come loose.
Another thing to look for is a metal silencer plate that is usually mounted along the side panels. This plate is glued on and is used for noise reduction. Sometimes it comes off and will rub against the drum.
If everything checks out good, remove the lower panel under the door by removing the screws under the bottom edge (HINT: Placing a small block of wood under the front feet of the dryer can make this easier). The panel will drop down then come off. If it gets stuck, tap on either side to knock it loose. Start the dryer again and look/listen for any noises coming from the drum supports. The drum rides on the drum supports and they require periodic cleaning and lubrication.
The drum light could be a lamp socket problem and/or wiring. Make sure you are using the correct bulb as well. I believe the bulb is only supposed to be a 25W bulb. This isn't related to any long dry time problem.
The heat problem could be directly associated to clogged dryer ducting. If the dryer is full of lint when you open it, you will have to thoroughly clean the vent ducting and interior cabinet. NOTE: This is a fire hazard!
Some things to try: Remove the dryer exhaust hose and start the dryer. The air leaving the back of the dryer should be forceful and hot (about 140 degrees F). If the air flow is weak and cool, you have a clog INSIDE your dryer. If the air flow is normal, check the vent ducting from where it leaves your dryer to where it exits your home. The dryer ducting should be cleaned routinely and kept clear of obstructions.
Your heat problem may not be a component at all. Double check your dryer interior and ducting and let me know what you find. I hope this helps you.
