Understanding the Problem
What the bearing does: The drum/shaft bearing supports the inner tub and allows the drum to spin smoothly. When bearings wear or fail the drum will rumble, wobble, leak and can eventually damage the tub or seal. Below are step-by-step diagnostic and repair instructions for a WM2050CW (confirm your exact model number before ordering parts). 1) Confirm the symptom and locate the problem a. Remove power and water supply to the washer. Unplug the washer. b. Manually spin the drum (with access through the door or by removing the belt): listen for grinding/rumbling and feel for smooth rotation. A healthy drum spins freely and quietly; a bad bearing will make a metal-on-metal rumble or feel gritty. c. Check for lateral play: rock the drum back and forth (push/pull perpendicular to spin axis). Excessive play (several millimeters) indicates worn bearing or loose hub. d. Inspect for leaks: look at the bottom cabinet and under the machine for oil or metallic debris — bearing failure often coincides with tub seal leaks. 2) Tools and parts to gather - Basic hand tools (sockets, screwdrivers, nut drivers, Torx bits if needed) - 3/8" or 1/2" drive ratchet and extensions - Pliers, rubber mallet or dead blow - Bearing puller or a hydraulic/presser tool (recommended but not strictly required if you have experience) - New bearing kit (bearing(s) + hub + seal) and tub seal (model-specific) - Shaft grease and anti-seize - Optional: replacement shock absorbers and spider if corroded 3) Disassembly (overview) — how to reach the bearing Note: This is an overview. Exact fastener types/locations vary; consult the WM2050CW service sheet/parts diagram. a. Unplug washer and shut off water. Move washer away from wall. b. Remove top panel (usually two screws at rear) and/or rear panel to access motor, belt, and drum shaft. Remove lower kick panel if fitted. c. Remove the drive belt and motor (if needed) to free the pulley/hub. On some models you can remove the belt and pull the inner tub out without removing the motor assembly. d. Remove the front door boot clamp and front panel if needed to separate the outer tub from the front. For front-access to the bearing you may need to split the inner and outer tub. e. Pull the inner tub/drum assembly out of the washer cabinet. Support the drum as you remove it — it’s heavy. 4) Separating tub and removing bearing a. Lay the tub on a workbench. Remove the retaining nut/bolt that holds the shaft or hub. Depending on design you may need to remove the drum spider (three-arm bracket) to access the bearing housing. b. Remove the old seal and bearing. Use a bearing puller or drift out the old bearing from the housing. Be careful not to damage the housing; if housing is corroded consider replacement. c. Clean the bearing housing thoroughly and inspect the shaft and spider for wear or corrosion. Replace cracked or corroded spider (common failure when bearing has failed). 5) Installing the new bearing and seal a. Heat the new bearing slightly or use a press to install it squarely into the housing. DO NOT hammer the inner race — force on the bearing inner race will damage it. Drive the outer race only when using a drift. b. Install the new tub seal (press in until flush). Make sure lips face the correct direction (check kit instructions). c. Reinstall the shaft/spider and torque any retaining bolts to the spec listed on the service sheet. d. Apply a light film of high-temp grease to the shaft where the seal contacts (only as recommended by kit instructions). 6) Reassembly and test a. Reinstall the inner tub into the outer tub, reattach front panel/boot clamps and all removed components in reverse order. b. Reinstall motor and belt, reconnect wiring and hoses, restore power and water. c. Run a spin-only cycle (no clothes) and listen for noise and watch for wobble or leaks. Check around the tub seal for water. 7) Final checks and notes - If you see continued wobble after new bearings are installed, re-check spider mounting bolts and ensure the hub/shaft was installed squarely. - Replace shock absorbers/suspension if they are worn — bad shocks increase bearing wear. Safety note: Always unplug the appliance and shut off water before starting. Bearings require force to remove/install; if you do not have a press or bearing puller, consider having a shop press the bearing or replace the entire tub assembly. Working with heavy tubs can cause injury — get help lifting.
Common Symptoms
Loud rumbling or grinding during spin, pronounced drum wobble or hop, water leaking from the front/bottom, and metallic debris in the drain pump trap.
Common Causes
- Normal wear over time — bearings wear out from heavy loads and years of use
- Water ingress past a failed tub seal causing bearing corrosion
- Imbalanced loads or worn suspension/shocks increasing bearing stress

Helpful Repair Tip
Remove the belt and spin the drum by hand while listening closely: a rough/gritty rumble or a distinct metallic grind that changes with drum rotation almost always means the tub bearing is failed.
Frequently Asked Questions
How long does it take to replace the drum bearing on a WM2050CW?
For an experienced DIYer with the right tools it typically takes 3–6 hours (includes disassembly, pressing out old bearing and installing new one, and reassembly). Without a press or experience plan for longer and consider professional help.
Is it worth replacing just the bearing or should I replace the whole tub/washer?
If the spider and outer tub are in good condition and only the bearing and seal are bad, replacing the bearing kit is cost-effective. If the spider is cracked, the outer tub is severely corroded, or the washer is old and has multiple failures (shocks, motor, electronics), replacing the entire tub assembly or the washer may be more economical. Always inspect the spider, housing, and suspension before deciding.
