WP8577376 is a genuine OEM Whirlpool Washer Agitator Shaft / Transmission Stem Seal. Because visually similar service parts can differ by model revision, connector, mounting, or specification, confirm the exact model before installation.

Compatibility: Designed for select Whirlpool washer models that specify WP8577376 in the service parts list. Model-number verification is required.

Fitment / What To Verify: Match the exact position/application, mounting shaft or bore, diameter/profile, and included hardware. Inspect companion rollers, shafts, belt, and idler parts so a worn mating component does not damage the replacement.

Please confirm fitment with your appliance or equipment model number before ordering.

Is it time to replace?

• Common Symptoms: Washer will not agitate or spin correctly, makes grinding noises, slips under load, or has excessive play in the drive system.
• Visible/Sensory Cues: Oil leakage, worn splines, damaged hub teeth, grinding, seized movement, or abnormal play at the drive components.

Pro Tip: Inspect the related belt/splutch, actuator, motor, bearings, and basket connection while the washer is open so another worn drive part is not missed.
