W10435302 Whirlpool Washer Seal and Bearing Kit is a combined sealing and bearing assembly designed for use in Whirlpool washing machines; it comprises one or more radial ball bearings and elastomeric sealing elements intended to mount around the drive shaft/tub hub interface. As a mechanical subassembly, the kit replaces worn bearing surfaces and the lip seals that exclude water and detergents from the bearing cavity, restoring the rotating interface to specified tolerances and protecting adjacent drive components.
Inside the appliance, the seal and bearing kit sits between the inner wash tub and the outer casing or transmission/gearcase, supporting the rotating mass of the tub and maintaining concentricity with the drive system. The bearings provide low-friction radial support for the shaft during spin and agitation cycles, while the seals prevent wash water and chemical contaminants from entering the bearing chamber or the gearcase sump. The component thus interacts directly with the drive shaft, tub/hub, transmission or motor coupling, and the wash tub sealing surfaces, and its condition affects vibration, noise, shaft runout, and leak control throughout the washer’s mechanical system.
This article will describe the kit’s functional design and typical materials, outline model and compatibility considerations for selecting the correct W10435302 replacement, identify common failure symptoms such as noise, axial or radial play, leaks, and oil contamination, and present diagnostic checks a technician or appliance owner can perform. It will also cover practical troubleshooting steps and replacement considerations-including necessary tools, bearing press and seal seating techniques, verification of shaft runout and alignment, and precautions to ensure sealing integrity-so readers can assess whether repair or full assembly replacement is required and how to approach the job with appropriate technical care.

Function and Role of the Washer Seal and Bearing Assembly in Load Transfer and Leak Prevention
The W10435302 Whirlpool Washer Seal and Bearing Kit contains the hub bearings and radial/axial sealing elements that locate the inner tub and transmit operational loads to the machine frame. The bearings carry the drum’s radial load (weight of the wet clothes and tub) and resist axial forces created by centrifugal acceleration and imbalance, maintaining concentric rotation and reducing shaft deflection. the sealing components form a fluid-tight boundary at the shaft and housing interface; their lips and dust lips prevent wash water and detergent from contaminating the bearing lubricant and housing. this kit is engineered to match the original equipment geometry for specific Whirlpool front-load assemblies, so fitment to the tub hub, shaft diameter, and housing recess must be checked during replacement to ensure proper preload and seal compression.
When bearings or seals begin to deteriorate, load paths change and the assembly exhibits characteristic symptoms: increased vibration, metallic grinding noises, heat buildup, and oil or grease carried into the wash tub. Seal breach allows water to reach bearing rollers and races, causing corrosion and rapid wear that amplifies vibration and leakage; conversely, a loose bearing increases shaft runout that stresses the seal lips. Typical service practice is to replace bearings and seals as a matched set,inspect the shaft and housing for scoring or pitting,and press-fit components to specified tolerances while maintaining correct axial preload. These measures restore proper load transfer and re-establish the leak barrier, reducing the risk of recurring failures.
- Primary functions: support radial/axial loads, maintain concentricity, and prevent fluid ingress.
- Common failure indicators: noise, wobble, grease in tub, and visible leaks at the front of the tub.
- Installation notes: verify part fitment, inspect mating surfaces, and follow press-fit and torque specifications.

How the W10435302 Whirlpool Washer Seal and Bearing Kit Works at the Tub‑to‑Transmission Spindle Interface
The W10435302 Whirlpool Washer Seal and Bearing Kit services the tub‑to‑transmission spindle interface by replacing the radial bearings and the dynamic seal that isolate the transmission from wash water and support the tub’s rotational loads. The bearings carry radial and small axial forces from the tub and agitator, while the seal’s elastomeric lip rides the shaft to prevent fluid ingress; correct orientation and interference fit of the seal and bearings are required to maintain the intended oil/water separation and bearing life. Installation requires pressing bearings to the specified seat, ensuring the shaft sleeve or spindle surface is within tolerance, and seating the seal so its lip contacts the shaft without rolling; improper seating, shaft scoring, or missing sleeves will allow leakage and accelerate bearing wear even if the kit itself is dimensionally compatible with the Whirlpool transmission model in use.
- Common symptoms indicating service at this interface: grinding or rumbling during spin, tub wobble, water or lubricant contamination in the sump, and visible scoring on the spindle.
- installation checks: verify shaft runout and surface condition, confirm bearing press depth, orient the seal lip toward the fluid source, and use the specified grease or lubricant sparingly to avoid washing out the seal.
| Item | Description |
|---|---|
| Seal | Elastomeric lip seal that prevents water ingress and retains lubricant at the spindle bearing area. |
| Bearings | Radial journal bearings sized to accept spindle loads and provide low-friction rotation; supplied as inner/outer set. |
In practical service, technicians should inspect the spindle for grooves or corrosion and determine whether a shaft sleeve or replacement tub/spindle assembly is required before installing the W10435302 Whirlpool Washer seal and Bearing Kit; reusing a damaged shaft will cause rapid recurrence of failure. During reassembly, verify bearing preload and axial play against factory specifications and run a short spin-up to check for noise, leakage, and temperature rise-normal bearings run cool and quiet, whereas elevated heat or persistent contamination indicates improper seating, incorrect parts, or remaining shaft damage that must be corrected to restore reliable operation.
Common Failure Symptoms: Noise, Tub Wobble, Axial Play and Water Ingress Indicative of Seal/Bearing Degradation
The W10435302 whirlpool Washer Seal and bearing Kit replaces the tub bearing and seal assembly that maintains shaft alignment and prevents washwater from reaching the bearing chamber. The bearing set supports radial and axial loads from the wash basket while the elastomeric seal retains lubricant and excludes water; degradation of either component leads to increased noise, eccentric tub movement and contamination of bearing grease. This kit is offered as a direct replacement for the original bearing and seal components on compatible Whirlpool washers,but technicians should verify model fit and inspect the shaft,bearing race and tub flange for scoring or deformation before pressing in new parts.
Bearing fatigue typically manifests as a low- to high-frequency grinding or growling that becomes louder under spin load, while seal failure is indicated by watery or discolored grease and accelerated corrosion of bearing surfaces. Practical diagnostics include a spin test to reproduce load-dependent noise,a visual check of grease at the seal lip,and measurement of radial and vertical clearances; measurable axial play-vertical movement of the tub of several millimeters when lifted by hand-usually signifies worn bearings or a damaged race. If inspection confirms wear or water ingress, replace the bearing and seal assembly, correct any scored mating surfaces, and reassemble with proper bearing press-fit and seal seating to restore alignment and service life.
- Grinding or growling during spin – metal-on-metal bearing contact
- Rhythmic knocking or wobble – eccentric basket from race wear
- Axial play visible when lifting the tub - excessive shaft or bearing clearance
- Watery, discolored grease or rust at the seal lip – seal breach and water ingress
| Item | Description |
|---|---|
| Noise | Load-dependent grinding indicates inner race or roller/ball wear |
| Axial play | Vertical displacement of several millimeters suggests worn bearings or shaft damage |
| Water ingress | Contaminated grease and rust at the seal indicate seal failure and accelerated corrosion |
Replacement Considerations, Model Compatibility and Stepwise Installation Best Practices
W10435302 Whirlpool Washer Seal and Bearing Kit contains the replacement bearings and tub seal used to restore concentric rotation and water containment at the outer tub hub. Bearings in this location support radial and thrust loads from the tub and drive assembly; when they wear or the seal fails, symptoms include grinding or rumbling during spin, excessive lateral play of the inner tub, and water leaks that accelerate bearing corrosion. Compatibility is determined by the drum/hub dimensions and the transmission/hub interface rather than the cabinet model alone, so confirm the appliance model/serial and compare hub outer diameter, bearing inner diameter, and seal lip profile against the kit specifications before ordering. Some Whirlpool/Maytag platforms use an integrated hub on the transmission or different bearing stack-ups, which require different kits or additional hub adapters; cross-reference service literature for the exact configuration prior to disassembly.
Follow a controlled sequence during replacement to avoid damage to the new bearings and seal: remove the agitator and access panels, support the tub, extract the worn bearings/seal with a suitable puller, clean and deburr the hub bore, press the new bearings squarely to the specified depth, and install the seal with a driver that seats it evenly without distorting the lip. Inspect the inner shaft for scoring and replace or polish it if necessary to ensure proper seal contact; apply only the recommended lubricant to bearing races (not to the seal lip) and tighten tub fasteners to the service manual torque values to maintain axial preload. After reassembly run a short diagnostic spin and a water-fill/leak check to verify noise-free operation, absence of axial play, and watertight sealing.
- Installation checklist: model verification, hub bore cleaning, correct press-in depth, seal orientation, torque to spec, no-load spin and leak test.
| Item | Description |
|---|---|
| Bearing type | Sealed roller bearings; ensure inner diameter and width match hub and shaft dimensions. |
| Seal material | Elastomeric lip seal with garter spring; check lip profile against tub flange. |
| Tools required | Bearing puller/press, seal driver, torque wrench, hub cleaning brushes. |
| Compatibility note | Verify appliance model/serial and hub dimensions; some transmissions require choice kits. |
Q&A
What exactly is the W10435302 Whirlpool Washer Seal and Bearing Kit and what parts are included?
The W10435302 is an OEM-style replacement kit intended to restore the tub bearing and seal assembly on compatible Whirlpool/Maytag/Kenmore washers. Kits vary by supplier, but typically include one or two tub seals, one or two bearings, a retaining ring or sleeve, and sometimes a gasket or spacer. Always check the part listing or the labels in the kit you receive to confirm the exact contents before starting the repair.
How do I know if my washer needs the seal and bearing kit replaced?
Common symptoms of failing tub bearings or seals are loud rumbling or grinding noises during spin,increased vibration or wobbling,and water leaking from the bottom of the washer (frequently enough appearing as puddles under the machine). If you hear a metallic or growling sound that changes with spin speed, or you see oil/grease around the back of the outer tub, those are strong indicators the bearings or seal are compromised.
Is this kit compatible with my washer model?
Compatibility depends on the exact model of your washer. W10435302 is used on a number of Whirlpool-family machines, but not all. Before ordering, check your washer’s model number (usually on a tag behind the door, on the back, or under the lid) and compare it to the part’s compatibility list from the parts supplier or Whirlpool’s parts diagram. If unsure, provide the model number to the supplier or consult an authorized service technician.
Can I replace the seal only,or should I replace the bearings simultaneously occurring?
While you can replace just the seal if the bearings are still quiet and free of play,it is indeed common and recommended to replace both bearings and seals together. Bearings often begin to fail soon after a leaking seal has allowed water and contaminants in; replacing both reduces the chance of having to disassemble the washer again shortly after repair.
How difficult is the replacement and what tools are required?
Difficulty is moderate to high for a DIYer. The job typically requires removing panels, the motor (on top-load machines) or front panel/door (on front-load machines), the inner drum/tub or stator assembly, and then pressing or driving the old bearings and seals out. Tools commonly needed include basic hand tools (sockets, screwdrivers, pliers), a bearing puller or appropriate drift and hammer, a seal driver or socket set for installing new seals squarely, and possibly a hydraulic press for stubborn bearings. If you don’t have the proper tools or experience, consider hiring a technician-improper installation can cause premature failure.
How long does the repair usually take and are there special procedures after installation?
For an experienced technician the replacement can take roughly 1.5-3 hours; a DIYer should plan on 3-6 hours depending on experience and tools.After installation, reassemble everything, reconnect water and power, and run a short test cycle (without clothes) to check for unusual noises, vibrations, or leaks. Some techs recommend a slow initial spin to confirm everything is aligned before a full-speed spin.
Should I buy an OEM W10435302 or an aftermarket kit, and is there a warranty?
OEM (Whirlpool-branded) parts generally ensure correct fit and materials; reputable aftermarket kits can be less expensive and still acceptable if they are rated for your model. Check the supplier’s warranty-many parts sellers and manufacturers offer limited warranties (often 90 days to 1 year). if your washer is still under manufacturer service coverage or you prefer guaranteed fit, choose the OEM part. Always keep your receipt and part numbers in case of warranty claims.
