Understanding the Problem
What this is: The bearings (and the bearing seal) support the wash tub and let it spin smoothly. On the MAH3000AWW a failed bearing or seal causes grinding or rumbling during spin, excessive wobble, and often a leak at the base of the tub. Below are numbered diagnostic steps followed by step‑by‑step repair instructions. 1) Diagnose the problem: a) Unplug the washer and shut off the water. b) Spin the empty tub by hand. Feel for roughness, resistance, or pronounced lateral play. c) With the washer on a floorboard, listen: press a long screwdriver against the outer tub and put the handle to your ear to amplify grinding sounds. d) Inspect for water on the floor or rust/oil at the bottom of the cabinet — a leaking tub seal often accompanies bearing failure. e) Try a high‑speed spin cycle (briefly) to confirm loud grinding/rumbling during spin. 2) Parts and tools check: You will usually need a tub bearing and seal kit specific to the model (order by MAH3000AWW), plus snap ring(s) if used. Typical tools: socket set, screwdrivers, bearing puller or slide hammer, seal driver or soft mallet, torque wrench, pliers, needle‑nose, bucket, shop towels, penetrating oil, and possibly a press. 3) Remove cabinet and access tub: a) Unplug washer and turn off water. b) Remove the agitator (puller may be required). c) Remove fabric softener dispenser and inner basket if necessary. d) Remove top and/or front cabinet panels per service manual to expose the tub and motor/drive assembly. 4) Remove drive components: a) Disconnect drive belt and motor (or gearbox) as required to free the tub. Support the tub so it doesn’t drop. b) Remove shock absorbers/springs that hold the tub. 5) Separate inner and outer tubs: a) Remove any retaining rings, clips, or bolts holding the inner tub to the outer tub. b) Lift and remove the inner wash basket (you may need a basket puller). c) With the inner tub removed you will see the bearing housing and seal at the bottom of the outer tub. 6) Remove old bearing and seal: a) Remove any retaining snap ring and pull the old bearing using a press or bearing puller. b) Drive out the old seal from the outside if required. Clean the bearing seat thoroughly, remove corrosion and old sealant. 7) Install new bearing and seal: a) Pre‑lubricate the new bearing lightly if manufacturer instructs (many bearings are pre‑lubed). Use a seal driver or a wide socket to press the new bearing squarely into the housing. b) Install the new tub seal from the outside into the tub; use a seal driver so it seats flush and square. c) Reinstall any snap rings or retaining hardware. 8) Reassemble: a) Reinstall inner basket, tub covers, shocks/springs, motor/gearcase, belt and other drive components. b) Reinstall cabinet panels, agitator, and dispensers. 9) Test: a) Reconnect the water, plug in the washer, run a no‑load spin and listen for smooth operation. b) Run a small test load and check for leaks around the base. Safety note: Bearings and tubs are heavy; get an assistant. Use appropriate eye protection and disconnect power before servicing. If you’re not comfortable with pressing/pulling bearings or separating tubs, consider replacing the whole outer tub assembly or hiring a pro. This guide assumes basic mechanical skills and access to a proper bearing puller/press.
Common Symptoms
Loud grinding or rumbling during spin, wobbling or excessive vibration, water leaking from bottom of washer, metallic scraping sounds, and failure to reach high spin speeds.
Common Causes
- Bearing wear from normal use and age (metal fatigue)
- Seal failure allowing water to reach and corrode bearings
- Overloading, frequent unbalanced loads, or impact damage
- Poor lubrication or contamination (rust, detergent residue)

Helpful Repair Tip
To confirm bearing failure: spin the empty basket by hand and feel for rough spots or excessive play; then put the handle of a screwdriver against the tub and your ear to amplify grinding — a bad bearing will produce a steady grinding or rumbling during spin.
Frequently Asked Questions
How much does it cost to replace the tub bearings on a MAH3000AWW?
Parts alone (bearing & seal kit) typically range from economical aftermarket kit prices up to higher OEM kit prices—expect parts to range from a modest amount to a couple of hundred dollars depending on source. Labor can be expensive because the job is time consuming (2–4 hours+), so professional repair costs commonly range from a few hundred dollars to over $500. You can save money by doing it yourself if you have the right tools.
Can I run the washer with a bad bearing until I get the part?
It’s not recommended. Running with a failing bearing can cause further damage (bigger failure of the tub, gearcase, or motor) and will usually allow the tub seal to fail and leak, risking water damage. If you must use it briefly, run low‑spin or small loads and monitor closely, but ideally stop using the washer until repaired.
