Understanding the Problem
Top-load washers (and some front-loaders) use a sealed transmission or gearcase that contains gears and bearings in a single assembly. When the internal bearing(s) wear or fail the unit often makes grinding, rumbling or continuous looping noises, struggles to agitate or spin, or starts to leak oil. Because the bearings are inside a sealed housing, the symptom set points to the transmission/gearcase rather than a simple external bearing or motor issue. A worn transmission bearing will usually present as a metallic rumble that increases with drum revolutions, intermittent or no spin/agitate, and sometimes oil or grease on the tub bottom. Repair typically requires replacing the entire sealed transmission or gearcase assembly, since most sealed transmissions are not designed to have internal bearings serviced in the field without a press and special machining. Replacing the gearcase restores the internal bearings, seals and gears to factory condition.
Common Symptoms
Grinding/rumbling noise during spin, continuous loop noise that changes with drum speed, loss of spin or agitation, oil/grease under tub, increased vibration or wobble.
Common Causes
- Normal wear of internal bearings due to age and load cycles
- Water intrusion and corrosion of internal bearings or seals
- Overloading or frequent heavy loads causing premature bearing wear

Helpful Repair Tip
Lift the washer tub and manually spin the transmission output shaft (or drum) with the belt removed—if you hear grinding, feel roughness, or see play at the shaft, the transmission bearing is failing and the gearcase should be replaced.
Frequently Asked Questions
Can I replace just the bearing inside a sealed washer transmission?
Usually no — most sealed transmissions are not designed to be disassembled and serviced at home. Bearings are pressed into the gearcase and may require a hydraulic press, specialty tools and machining to replace properly. In most cases it's faster and more reliable to replace the entire sealed transmission/gearcase assembly or purchase a manufacturer-approved rebuild kit for your exact model if one exists.
How much does it cost and how long does the repair take?
Parts for a sealed transmission/gearcase typically range from a few hundred dollars to over $500 depending on make and model; labor is 1–3 hours for an experienced tech. If a full replacement is required, expect total repair costs (parts + labor) commonly between $300–$800. If an older machine is affected, compare repair cost to replacement cost before proceeding.
