Whirlpool Dryer Making Loud Noise — 5 Causes & How to Fix

Your Whirlpool dryer sounds like it's churning gravel instead of clothes. One user described it perfectly: "I followed instructions all went well except for the belt install, if I had a diagram it would have a lot easier. I did get it after 3 attempts." That noise you're hearing? It's usually worn drum support components screaming for replacement.

The 4392067 dryer repair kit addresses the most common noise sources in Whirlpool, Maytag, and Kenmore dryers. This comprehensive kit includes drum rollers, idler pulley, and belt—the holy trinity of dryer noise issues. Models like the WED5500XW0, WED8000DW3, and WED9400SW1 are particularly prone to these failures after 5-7 years of regular use.

Quick Symptom Check

• Thumping or rumbling during the entire cycle
• Squealing or screeching that changes pitch
• Grinding noise from the back of the dryer
• Drum won't spin or spins unevenly
• Black marks appearing on your clothes

If you're experiencing any combination of these symptoms, you're likely dealing with worn drum support components. Let's diagnose which parts have failed.

Cause #1: Worn Drum Support Rollers (Probability: 65%)

The drum support rollers bear the entire weight of your wet laundry—sometimes 20+ pounds spinning at high speed. Over time, the rubber coating wears away and the bearing seizes up. When this happens, you'll hear a distinctive thumping or rumbling noise that sounds like someone's throwing shoes in the dryer.

How to diagnose: Unplug the dryer and manually spin the drum. If it feels rough or you hear grinding, the rollers are shot. On models like the WED7300XW0 and WED8200YW0, you can actually see the worn rollers through the front panel if you shine a flashlight inside.

The fix: The 4392067 kit includes four new drum rollers with tri-rings. You'll need to remove the dryer drum to access them—not a quick job, but doable in about 90 minutes with basic tools. Pro tip: Replace all four rollers even if only one looks worn. They wear at roughly the same rate, and you don't want to do this job twice.

Cost: $58.99 for the complete kit vs. $200-350 for a service call

Cause #2: Failed Idler Pulley Assembly (Probability: 25%)

The idler pulley keeps tension on your dryer belt. When its bearing fails, you'll hear a high-pitched squealing or screeching noise that changes pitch as the drum speeds up or slows down. Some folks describe it as sounding like a dying mouse.

How to diagnose: Remove the front panel and watch the idler pulley while someone manually rotates the drum. A bad pulley will wobble, or the bearing will feel gritty if you spin it by hand. The WED5600XW0 and WED7500GW0 models are notorious for idler pulley failures around the 6-year mark.

The fix: The 4392067 kit includes a new idler pulley assembly. Once you've got the drum out for the rollers, swapping the idler takes maybe 5 extra minutes. It's held on with a single bolt.

Warning: A seized idler pulley puts extra strain on your motor and can cause the belt to burn—which brings us to the next issue.

Cause #3: Damaged or Worn Drive Belt (Probability: 20%)

The drive belt wraps around your drum and connects to the motor. After years of friction and heat cycles, the belt develops cracks, glazes over, or even snaps. When it's damaged, you might hear squealing, or the drum simply won't turn at all.

How to diagnose: If your dryer drum won't spin but the motor runs, that's a broken belt 99% of the time. For worn belts that still work, look for shiny spots (glazing), cracks, or frayed edges. Models WED8000DW4 and WED9050XW0 typically go through belts every 7-10 years.

The fix: Belt replacement is the trickiest part of this repair. As one user noted: "I followed instructions all went well except for the belt install, if I had a diagram it would have a lot easier. I did get it after 3 attempts." The belt routes around the drum, under the idler pulley, and around the motor pulley in a specific pattern. Take a photo with your phone before removing the old belt—you'll thank yourself later.

Installation tip: Use a long flat-blade screwdriver to help guide the belt around the motor pulley. It takes finesse, not force.

Cause #4: Loose or Worn Drum Glides (Probability: 15%)

Drum glides (also called drum slides) support the front of the drum as it rotates. When they wear down or come loose, the drum can tilt forward and scrape against the front panel, creating a grinding or scraping noise. You might also notice black marks on your clothes from the friction.

How to diagnose: Reach inside the drum and try to lift the front edge up and down. If there's more than 1/4 inch of play, your glides are worn. On WED7500GC0 and WED8500BW0 models, worn glides sometimes leave a black residue trail on the inside of the door.

The fix: Drum glides aren't included in the 4392067 kit, but they're cheap (under $10) and easy to replace while you've got the drum out. Just peel off the old adhesive-backed glides and stick on the new ones.

Cause #5: Foreign Object in Blower Housing (Probability: 10%)

Sometimes the noise isn't from worn parts at all—it's from a coin, button, or underwire bra that escaped through the drum seal and got stuck in the blower wheel or housing. This creates a rattling, ticking, or clanking noise that changes with drum speed.

How to diagnose: The noise will sound distinctly metallic and rhythmic. Remove the front panel and check the blower housing and lint trap area for foreign objects.

The fix: Fish out the offending item with needle-nose pliers. While you're in there, clean out any lint buildup—it's a fire hazard and reduces dryer efficiency.

What You'll Need for This Repair

According to the installation notes, you'll need:

• 1/4-inch nut driver
• Long flat-blade screwdriver
• Short flat-blade screwdriver
• Phillips screwdriver
• Work gloves (those drum edges are sharp)
• Phone camera (to document belt routing)

Most important: Disconnect the dryer from power at the circuit breaker before starting. This isn't a suggestion—240 volts will ruin your whole day.

When to Call a Pro

This repair requires removing the dryer drum, which means dealing with the belt routing and potentially the rear bulkhead. If you're not comfortable with that level of disassembly, call a tech. However, the parts cost the same whether you DIY or hire out, so you're really just paying for labor ($150-250 typically).

One user summed it up nicely: "Parts fit perfectly. Save time and money by getting genuine parts." Another confirmed: "A+ seller, parts fit as expected, dryer is up and working great again."

If your dryer is over 12 years old or you've already done this repair once before, it might be time to consider replacement. But for most dryers under 10 years old, the 4392067 kit will buy you another 5-7 years of reliable service.

Frequently Asked Questions

How long does the 4392067 repair kit installation take?

Plan on 60-90 minutes for your first time, assuming you're moderately handy. The drum removal is the time-consuming part. Once you've got access to the rollers and pulley, the actual parts swap takes maybe 20 minutes. The belt reinstallation can be frustrating—give yourself patience and maybe 15 minutes to get it routed correctly.

Will this kit work on my Kenmore or Maytag dryer?

Yes, if it's a Whirlpool-manufactured dryer (most Kenmore and Maytag dryers made after 2000 are). The 4392067 replaces OEM part numbers AP3109602, PS373088, 587637, and 80047. Check your model number against the compatibility list—it covers dozens of Whirlpool, Maytag, and Kenmore models including WED5500XW0, WED8000DW3, and WED9400SU1.

Can I just replace the worn parts instead of using the whole kit?

You could, but you shouldn't. Here's why: if your drum rollers are worn enough to make noise, your idler pulley and belt aren't far behind. Do the job once with the complete kit, or do it again in 6-12 months when the next component fails. The 4392067 kit is priced so that buying it is actually cheaper than sourcing the individual components separately. Plus, you're already in there with the drum removed—might as well do it right.
