When it wears out or tears, water migrates along the drum shaft, soaks the bearing, and drips onto the floor — and if left unaddressed, the bearing fails next, turning a $15 repair into a $200+ one. \u003cstrong\u003e⚡ One of the most common wear items on Whirlpool top and front load washers — the seal degrades naturally over years of thermal cycling and detergent exposure.\u003c\/strong\u003e \u003cstrong\u003ePart WP8577374\u003c\/strong\u003e is the genuine OEM replacement that stops the leak and protects the bearing from water damage immediately.\u003c\/p\u003e\n\n\u003ch3\u003e❓ Is This the Right Part?\u003c\/h3\u003e\n\u003cp\u003eThis is the correct fix if ALL of the following are true:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e✔ The washer runs normally — fills, agitates, and spins\u003c\/li\u003e\n\u003cli\u003e✔ No hose connections or door gasket leaks are visible\u003c\/li\u003e\n\u003cli\u003e✔ Water appears under the machine during or after the spin cycle\u003c\/li\u003e\n\u003cli\u003e✔ ONLY problem is water on the floor — originating from the center\/bottom of the tub area\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNot sure? \u003ca href=\"\/pages\/contact\"\u003eSend us your model number\u003c\/a\u003e — we'll confirm before you order.\u003c\/p\u003e\n\n\u003ch3\u003e🔧 Common Symptoms\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eWater pooling under the washer during or after spin cycle\u003c\/li\u003e\n\u003cli\u003eRust staining or mineral deposits on the floor beneath the machine\u003c\/li\u003e\n\u003cli\u003eRumbling or grinding noise during spin — bearing already water-damaged\u003c\/li\u003e\n\u003cli\u003eMusty smell from the washer cabinet — water reaching the bearing area\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e✔ If these symptoms match, this is the most likely failed component in the system.\u003c\/p\u003e\n\u003cp\u003e✔ In most cases, replacing this shaft seal stops the leak immediately and prevents bearing failure.\u003c\/p\u003e\n\n\u003ch3\u003e📦 Part Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e WP8577374\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Washer Drum Shaft Seal \/ Tub Bearing Seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces:\u003c\/strong\u003e 8577374\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrands:\u003c\/strong\u003e Whirlpool, Maytag, Kenmore\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"upsell-box\"\u003e\n\u003cstrong\u003e⚠️ Strongly Recommended — Replace the Bearing at the Same Time:\u003c\/strong\u003e\u003cbr\u003e\nIf the seal has been leaking for any length of time, the drum bearing has almost certainly been contaminated with water. Replacing the seal without replacing the bearing is the most common reason for a repeat repair within 3–6 months. The bearing and seal are a matched service pair — do both while the machine is apart and you won’t be back inside it again.\n\u003c\/div\u003e\n\n\u003ch3\u003e⚙️ Installation\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSkill Level: ADVANCED — 60–90 minutes.\u003c\/strong\u003e Disconnect power and water supply before servicing. Access requires disassembling the washer cabinet and removing the outer tub to reach the bearing and seal assembly at the drum shaft. Press the old seal out, clean the bearing seat, and press the new seal in flush. Reassemble in reverse order and run a full cycle to confirm the leak is resolved before closing the cabinet.\u003c\/p\u003e\n\n\u003ch3\u003e✓ Compatible Models\u003c\/h3\u003e\n\u003cp\u003eCompatible with a range of Whirlpool, Maytag, and Kenmore top and front load washer models. \u003ca href=\"\/pages\/contact\"\u003eContact us to verify your model number\u003c\/a\u003e before ordering.\u003c\/p\u003e\n\n\u003ch3\u003e💡 Pro Tip\u003c\/h3\u003e\n\u003cdiv class=\"pro-tip\"\u003e\n\u003cstrong\u003eThe $15 Fix That Prevents a $200 Repair:\u003c\/strong\u003e\u003cbr\u003e\nA shaft seal costs under $20. A drum bearing costs $40–$80. A full outer tub assembly (when the bearing seizes and damages the tub) can run $150–$300 plus labour. The seal is the canary — when it leaks, replace it immediately along with the bearing before the bearing seizes. Every week of delay with a leaking seal is water soaking into the bearing race, accelerating failure. This is one of the highest-ROI repairs in appliance service.\n\u003c\/div\u003e","brand":"XPart Supply Ltd.","offers":[{"title":"Default Title","offer_id":52804055564577,"sku":"WP8577374","price":14.94,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0897\/7783\/2225\/files\/Whirlpool_Washer_Shaft_Seal_WP8577374_Fixes_Drum_Bearing_Leak_Water_Under_Washer.png?v=1780690049","url":"https:\/\/xpartsupply.com\/products\/whirlpool-wp8577374-washer-shaft-seal","provider":"XPart Supply Ltd.","version":"1.0","type":"link"}
