Maytag MHW6630HW Bearing Replacement Guide

Hi, I’m Drew Callahan. After traveling over 80,000 miles across North America in three different rigs, I’ve had my hands on the Maytag MHW6630HW more times than I can count. Bearing failure is one of the most common issues I’ve encountered with this front-load model, typically emerging after about 4-6 years of heavy use. That rumbling or grinding noise during the spin cycle? It almost always points to a worn drum bearing and seal kit. Replacing them together is the best way to ensure a proper fix.

🔨 Pro Tip from Drew

When working on the MHW6630HW, always replace the rear drum bearing alongside the tub seal (part number W10435302) as a matched set. Skipping the seal is the number one mistake I see DIYers make, leading to premature bearing failure within months. Also, while you have the drum out, take a close look at the spider arm bracket; these can crack and are a cheap insurance to replace while everything is apart.

Common Symptoms & Causes

If your Maytag MHW6630HW is showing signs of worn drum bearings, you’ll likely notice one or more of these symptoms during operation.

A loud grinding, rumbling, or metal-on-metal scraping noise during the spin cycle
Excessive drum wobble or vibration felt through the washer cabinet
A burning rubber or metallic smell after running a wash cycle
The drum spins unevenly or produces a rhythmic thumping at high speeds

These symptoms are typically caused by normal wear and tear on the rear drum bearing, which deteriorates over time due to constant exposure to heat, moisture, and heavy loads.

Safety First

Unplug the washing machine from the power outlet before starting any repair — never work on a live appliance.
Shut off the water supply valve before disconnecting any water lines or hoses.
Wear work gloves when handling metal brackets, sheet metal edges, or sharp components.
Take photos with your phone before disconnecting any wiring harnesses or connectors.
Work in a well-lit area with enough floor space to lay removed panels flat.

Step-by-Step Repair Instructions

Step 1

Start by opening the washer door and spinning the drum slowly by hand to diagnose the failure. If you hear a loud grinding or rumbling noise, it points to worn drum bearings. If there’s a wobble in addition to grinding, both a failed spider arm and bearings may be at play. Knowing which parts are involved allows you to order everything you need upfront. Remember to unplug the machine and turn off the water supply before you start.

Step 2

Replacing the bearings on the MHW6630HW requires complete disassembly since the bearing is pressed into the outer tub, which needs to be split open to access it. Begin by removing the door boot seal (release the wire spring retaining ring), then detach the front panel (four T20 Torx screws and the counterweight bolts using a 13mm socket). After that, take off the rear panel (four T20 Torx screws and five bolts securing the rear bearing cover). Pro tip: Take photos of each wire harness connector and hose position before removal for easier reassembly.

Step 3

Separate the outer tub halves by unclipping all 12 retaining clips around the seam. Next, remove the spider arm by unthreading the three 8mm bolts that attach it to the drum shaft. With the drum free, press the old bearing out of its seat in the rear tub half — use a bearing press or a correctly sized socket and threaded rod for this, as hammering unevenly can crack the plastic tub. Inspect the spider arm closely for hairline cracks radiating from the hub; a cracked spider will ruin a new bearing quickly.

Step 4

Press the new bearing squarely into the outer tub seat so it sits evenly — an improperly seated bearing can lead to premature failure and damage to the tub. Install the new tub seal around the bearing to prevent water from tracking down the shaft and causing rust or additional failures. Torque the spider bolts to exactly 20 ft-lbs in a star pattern; under-torquing can allow micro-movement that accelerates wear, while over-torquing risks cracking the spider hub.

Step 5

Rejoin the tub halves and work all 12 clips around the seam until they snap fully closed, ensuring there are no gaps that could leak during operation. Reassemble the machine in reverse order: start with the rear panel, torque the counterweight bolts to 30 ft-lbs to secure the weight during high-speed spins, then attach the front panel. When seating the door boot seal, start at the 6-o’clock position to ensure it seats evenly around. Pro tip: Run your finger around the boot seal lip after installation to confirm it’s fully captured in the front panel groove with no folds that could cause a leak.

Step 6

Reconnect the power and water, then run a full spin cycle while observing the machine closely. A successful repair should produce no grinding or rumbling noise and a drum that spins without any lateral wobble. If grinding persists, recheck spider torque and bearing seating before assuming you have a defective part.

Where to Buy Replacement Parts

You can find genuine OEM and aftermarket replacement parts for your Maytag MHW6630HW (Front Load) on Amazon:

When to Call a Professional

If the issue continues after following all the steps above, the problem might involve a failed main control board, a worn drive motor, or issues with wiring that require specialized diagnostic tools. In that case, it’s wise to contact a licensed appliance technician — and remember to shut off both the hot and cold supply valves before any work that opens the fill circuit.

How Much Does This Repair Cost?

Replacing the bearings on a Maytag MHW6630HW yourself typically costs between $40–$100 for the bearing kit and drum seal. A professional repair, on the other hand, usually runs $150–$300 once you factor in labor and service fees. Taking on this repair yourself can save you $100 or more, making it well worth your effort.

Frequently Asked Questions

How do I know if the bearings on my Maytag MHW6630HW need replacing?

A loud rumbling or grinding noise during the spin cycle is the most common sign of worn drum bearings. You may also notice the drum wobbling or excessive vibration during operation.

Is bearing replacement on the Maytag MHW6630HW a DIY-friendly repair?

This repair is considered advanced and requires disassembling the outer tub, which can be time-consuming. Homeowners with mechanical experience can complete it, but I recommend hiring a technician if you’re unsure.

What parts do I need to replace the bearings on this model?

You’ll typically need a new bearing kit compatible with the Maytag MHW6630HW, which includes the drum bearing and tub seal. Always replace the seal along with the bearing to prevent future water leaks.

The Rear Drum Bearing Kit That Stops That Grinding Noise on the MHW6630HW

When that metal-on-metal grinding noise kicks in during the spin cycle, it’s a clear sign that the rear drum bearing has failed — and this is the part you need to replace. I’ve seen too many people make the mistake of replacing just the bearing without the seal, thinking the old seal is still good. Trust me, it’s better to order the complete bearing kit upfront to avoid doing this job twice.

What Works

Direct fit for the MHW6630HW — no adapter plates or machine work needed; the bearing goes straight into the tub housing as if it came from the factory.
Kit includes both the bearing and seal together, ensuring you’re not replacing one and watching the other fail six months later.
Noise stops immediately after installation — I’ve had customers reach out just to say the rumbling is completely gone.

What Doesn’t

Installation still requires pulling the front panel, drain pump, and tub — this isn’t a 20-minute job even with the right kit in hand.
If the drum spider arm is also cracked or bent (check it while you’re in there), the bearing kit won’t solve that separate issue.

I’ve made the mistake of ordering just the bearing without the seal, thinking the old seal was still good — it wasn’t, and neither is the customer’s goodwill when water starts leaking three weeks later. Order the complete kit from the start. Rear drum bearing kit
