This Part Fixes These Problems

Leaking Water

Washer leaks water from the outer tub or from above the transmission area during wash or spin cycle — a classic sign of a failed tub seal.

Loud Grinding or Rumbling Noise

A worn or cracked tub seal allows water to reach the bearings, causing loud grinding, roaring, or rumbling sounds during the spin cycle.

Marks or Stains Left on Clothes

A deteriorating seal can allow bearing grease or dirty water to contaminate laundry, leaving dark stains or marks on clothes after washing.

Excessive Vibration and Leaking Water

Washer leaks water from above the transmission area during wash or spin cycle — a classic sign of a failed tub seal.

Loud Grinding or Rumbling Noise

A worn or cracked tub seal allows water to reach the bearings, causing loud grinding, roaring, or rumbling sounds during the spin cycle.

Marks or Stains Left on Clothes

A deteriorating seal can allow bearing grease or dirty water to contaminate laundry, leaving dark stains or marks on clothes after washing.

Excessive Vibration and Shaking

When the tub seal and bearings fail, the drum loses smooth rotational support, leading to severe shaking and vibration during high-speed spin.

Product Description

Why Choose Our 4036ER2004A Washer Tub Seal Gasket?

🔧
Built to OEM SpecificationsEngineered to exact OEM dimensions of approximately 2.9" x 2.6" x 0.5" — forms a watertight seal between the rear tub and drive shaft, just like the original LG part.
💧
Stops Leaks DeadCreates a tight seal between the inner and outer tubs during the wash cycle, preventing water from escaping around the transmission area.
🏗️
Fluororubber + Steel Plate ConstructionExternal fluororubber and internal steel plate design delivers superior heat and chemical resistance — built to outlast cheap silicone-only alternatives.
🔄
Direct-Fit ReplacementReplaces OEM part numbers AP4438637, PS3522855, AH3522855, EA3522855, and 1267489. No modifications required — drop-in fitment for all listed LG and Kenmore models.
🧺
Wide CompatibilityFits a broad range of LG front-load washers and Kenmore/Sears models, including popular models like WM2432HW, WM2487HRM, WM3431HW, and Kenmore 79640311900.
🛡️
Pre-Lubricated Mating SurfaceInternal pre-lubricated design reduces friction at installation and during operation, protecting your bearings and extending the life of the entire tub assembly.

💡 Pro Tip: How to Know Your Tub Seal Has Failed

Your part is likely the culprit if you notice any of the following:

⚠️ Water leaking from the outer tub or from above the transmission area during operation

⚠️ Loud rumbling, grinding, or roaring noise while the drum is spinning

⚠️ Excessive moisture or puddles found under or around the washer after a cycle

⚠️ Dark grease marks or stains left on clothes after washing

Pro Tip: When replacing the tub seal, always inspect and replace the tub bearings (4280FR4048L and 4280FR4048E) at the same time. A failed seal is almost always accompanied by bearing damage — replacing just the seal without the bearings often results in repeat failures within months.

Questions & Answers

Will this tub seal fit my LG WM2487HRM washer?
Answered by Support Team  ·  Mar 15, 2024
Yes, the 4036ER2004A tub seal is a confirmed direct fit for the LG WM2487HRM. It is also compatible with WM2487HRMA, WM2487HWM, and WM2487HWMA. Always verify your full model number before ordering.
Do I need to replace the bearings at the same time as this seal?
Answered by Support Team  ·  Nov 20, 2023
Strongly recommended. A failed tub seal almost always allows water to enter and damage the tub bearings (4280FR4048L and 4280FR4048E). Replacing the seal alone without inspecting and replacing the bearings frequently leads to repeat failure within a short period. Replace both at the same time to save yourself from tearing the machine apart again.
What are the dimensions of the 4036ER2004A seal?
Answered by Support Team  ·  Jan 8, 2025
The 4036ER2004A seal measures approximately 2.9 inches (outer diameter) x 2.6 inches (inner diameter) x 0.5 inches (thickness). It is black in color and features an external fluororubber layer with an internal steel plate for durability.
Is this part compatible with Kenmore washers?
Answered by Support Team  ·  Jul 22, 2024
Yes. The 4036ER2004A tub seal is compatible with a range of Kenmore/Sears front-load washer models, including 79640272800, 79640311900, 79640318900, 79640441900, 79640512900, 79641022900, 79641028900, 79642192900, and others. Kenmore washers in this range are manufactured by LG and use identical internal components.
How difficult is it to replace the 4036ER2004A tub seal myself?
Answered by Support Team  ·  Feb 10, 2026
This is considered a hard-level DIY repair requiring 2–3 hours minimum. It involves disassembling most of the washer including removing the front panel, counterweights, outer tub, and splitting the tub halves to access the seal and bearings. We recommend this repair only for those with prior appliance disassembly experience. Using a YouTube video guide for your specific model is strongly advised. If you are not mechanically confident, professional service is recommended.

We typically respond within 1 business day. Include your appliance model number for the fastest answer.
