The short answer first
On the NGD dryer this symptom is usually the glides and felt the drum runs against at the front, which wear to nothing and let metal touch metal. The NGD family splits across trim and finish suffixes rather than across different machinery, so the order below holds for every one of them.
What an owner actually sees
- A high squeal that rises and falls with the drum — A bearing under belt tension, which is the idler far more often than anything else.
- A fast metallic rattle much quicker than the drum — Blower speed, which means something loose has reached the blower wheel.
- A constant drone from the moment the machine starts — Unchanging noise is the motor rather than anything the drum drives.
- Scraping, with grey marks appearing on light clothing — Front glides or felt worn through to metal.
- NEAR MISS — a loud bang and then the drum stops turning — A noise that ends in no rotation is a broken belt or a seized part, and the will-not-start page covers what to do next.
Causes, most likely first on the NGD family
- Front glides or felt seal worn through — Top of the list here. It is a cheap part with a tedious access, which is exactly the combination people put off until something else fails too.
- Machine not level or walking on the floor — Second here. A short foot or a springy floor produces a low-frequency thump that changes completely when the machine is moved a few inches.
- Rear drum bearing or shaft support worn — Third on this platform. It is the noise least worth ignoring, because a seized bearing takes the drum and sometimes the motor with it.
- Loose panel, missing screw or ducting rattling — Fourth: possible, but not where to start. A missing screw at the back panel or a duct clamp that has slipped rattles only during part of the cycle, which is why it seems intermittent.
- Body: A brand-generic article on this symptom starts with the drum support rollers. Here the front glides or felt seal moves ahead of it, because the variants here differ in finish rather than in mechanism, so one subsystem carries the whole family.
The order to work in
- Look for scorch marks or grey scuffing on light-coloured washing — Marks on clothing alongside a scraping noise names the front seal without opening anything.
- Rock the machine at each corner and level it properly — If the noise changes when you move the machine, no part has failed.
- With the machine isolated, turn the drum by hand and feel for roughness — Roughness or resistance you can feel through the drum by hand is a bearing rather than a belt.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. A dryer is heavy and its cabinet edges are sharp, so get help before moving it and never reach into a drum or a blower while power is connected. If the machine is gas-fed, do not move it far enough to strain the flexible connector; if you smell gas, leave the building and call the gas utility from outside.

Where the owner fix stops
Call promptly for grinding that is getting worse, since a seizing bearing damages parts that are currently fine. Stop using the machine and call if the noise is accompanied by a burning smell or by marks appearing on clothing.
