Drum rotating unevenly, squeaking

Your drum rollers may be going bad (grinding noise) which will sometimes cause the drum to drop slightly, creating a gap where the clothes get caught as the drum rotates. (black streaks)

these are the parts, Tim:

drum rollers/glides, may be that the motor needs to be oiled, in which case you will need to unplug dryer and drill a hole in the casing not to deep just to where it goes through the casing, then moisten the cotton fabric. Hope this helps Tim:

Sounds like you front drum support / bearing is wearing out. When the support wears out, a gap occurs between the drum and drum support, That is where the clothes are getting caught, Does your dryer squeak when running? If so, then replace the front drum support / bearing. Cost about $35 - $40.

Your drum seal between the drum and the body of the dryer needs replacement, this is what causes the clothes to stick and tear holes in them.
I hope this helps

Our Hotpoint DLL2650 has the same symptom. A bearing has been squeaking for over a year. Now one of the drum rollers makes a grinding sound against the drum. I suspect the drum roller has come apart.

A great number of dryer drums rotate on a type of felt material. After many years of use this material thins, allowing the drum to make some contact with the metal housing beneath - hence the 'squeak.'

Squeak is caused by a worn out roller rolling metal to metal - Most dryers have rollers, felts and drum slides to balance drum rotation:
When rollers wear off, black powder leaks to rear felts and black marks are left on clothes.
Same thing happens when drum slides wear off (black marks are left on clothes)

Squeaking is the rear drum bearing. The rest is the front drum slide supports. After a number of years, these wear and need replacing. Without the model number I can't give you the part numbers that fit your machine.

Open the service panel and look for a broken belt and does the motor spins. Let me know if you will need for further assistance. Good luck!
