[Newest] 4392067 Dryer Repair Kit and W10837240 Dryer Idler

The Verdict

A dryer that squeals like a tortured bird every time it runs isn’t just annoying — it’s a warning. That noise is almost always the idler pulley or the belt, and this two-part kit from the “Newest” line targets exactly those failure points. But does it actually fix the problem, or just quiet it temporarily?

I tore into the specs, cross-referenced the part numbers, and dug through buyer feedback to give you the straight story.

What’s Actually in the Box

You get two components: the 4392067 dryer belt (a 92.5-inch, 4-rib belt) and the W10837240 idler pulley assembly. That’s it — no rollers, no glides, no instruction sheet. For most Whirlpool-built machines (that includes Maytag, Kenmore, and Amana brands from roughly 2000 onward), these are the two wear items that cause the classic high-pitched squeal during operation.

The pulley has a sealed bearing and plastic wheel that measures about 2 inches across. The belt is the standard ribbed style with the proper width to ride in the drum groove.

Real-World Performance

Here’s what the 210 Amazon ratings at 4.2 stars actually tell you: this kit fixes the problem for the majority of buyers, and the few who had issues mostly ran into fitment confusion, not defective parts.

The pulley spins freely right out of the box — no gritty feeling, no wobble. That matters because a rough-spinning pulley is what causes the squeal in the first place. Multiple reviewers confirmed the fix worked immediately after installation.

One buyer put it plainly: “Fixed my squeaky Maytag. Took 20 minutes with a YouTube video. Quiet as new.”

Another noted the build quality compared to OEM: “The pulley is identical to the Whirlpool original. Same markings. Same fit.”

Where It Falls Short

The main frustration: there’s no installation guide. If you’ve never opened up a dryer before, you’ll be lost. The good news is that this kit is popular enough that a quick search for “4392067 dryer repair” pulls up dozens of walkthrough videos.

The belt also ships tightly coiled. If you install it immediately without letting it relax, it can twist and cause the drum to bind. Give it 30 minutes to straighten out before you start.

One more consideration — this kit doesn’t include the drum rollers or the felt seal. If your dryer is also thumping (not just squealing), you’ll want to order those separately. The $20–30 you save doing it yourself is real, but only if you’re comfortable with a screwdriver and a couple of hours of your Saturday.

Who Should Buy This

• DIY homeowners with a basic tool kit who want to skip a $150–200 service call
• Owners of Whirlpool/Maytag/Kenmore dryers from the 2000s–2010s that have started squealing
• Budget-conscious repairers who want OEM-equivalent parts without the OEM markup

Skip it if your dryer is making grinding or rumbling noises — that points to drum rollers or bearings, which this kit won’t fix.

FAQ

Q: Will this fit my specific dryer model? A: If it’s a Whirlpool, Maytag, Kenmore, or Amana dryer with a 92.5-inch belt, yes. Check your model number against the compatibility list on the product page — if yours isn’t listed, measure your old belt before ordering.

Q: How long does installation take? A: For someone with basic mechanical ability, 20–45 minutes. You’ll remove the top panel, access the belt and pulley, swap both parts, and reassemble. Watch one video first if you’re unsure.

Q: Can I just replace the pulley and keep my old belt? A: You can, but don’t. The belt is cheap, already included, and if the pulley failed, the belt has been running with improper tension — it’s likely stretched. Replace both together.

The Verdict

Buy it if: You have a Whirlpool-built dryer that’s squealing, you’re comfortable with basic DIY, and you want to fix it for the cost of a pizza instead of a service call.

Skip it if: You have zero tool experience, your dryer is making grinding noises (that’s rollers/bearings), or you want a printed manual included.

At 4.2 stars with 210 ratings, this kit earns its score. It’s not flashy, but it does exactly what it promises — and for most buyers, that means a quiet dryer and a satisfying DIY win. 4.2/5 stars.
