W10435302 Whirlpool Washer Seal adnā Bearing Kit isā a sealed bearing and sealing⤠assembly intended for teh rotating tub of compatible whirlpool washing machines. As a mechanical component set, the kit typically provides the bearings that support theā inner tub or⣠drum and the seals that ā¤isolate those bearings from⤠wash ā¢water ā¢and contaminants; it is a press-fit assembly that restores rotational support and water containment where⤠wear or damage has occurred.
Inside the appliance the bearings carry radial and axial loads from the spinning drum and transmit those⣠loads into āthe washer’s rear housing or transmission, while the⢠seals prevent āwash water, detergent and⤠lint from entering the bearing cavities. The assembly therefore interfaces directly with the drive system (motor, pulley orā direct drive coupling), the inner and outer tubsand the washer’s water containment system;ā correctā bearing fit, seal orientation and lubrication are essential to maintain concentric rotation, minimize vibrationand protect against premature corrosion and ā£contamination of bearing surfaces.
In this article readers will find a technical overview of āthe kit’s function ā¢and typical construction,⢠guidance on model compatibility and how to verify whether W10435302 is the correct replacement for a given machine, common failure symptomsā to watch for (noise, wobble, leaks and increased vibration), troubleshooting checks to help isolate bearing- or seal-related faultsand practical replacement ā¤considerations such as inspection points, press-fit removal/installation issuesand post-replacement verification procedures useful to technicians, engineers and informed⤠appliance owners.

Functional ā¤Role⢠and Mechanical⢠Requirements of the Washer Seal and Bearingā Assembly
The washer tub ā£bearing and seal assembly provides two linked mechanical functions: the bearing supports radialā and⤠axial loads from ā¢the ā¤rotating drum and transmissionand the seal prevents water and detergent from entering the bearing cavity. The W10435302 Whirlpool Washer Seal and Bearing Kit āsupplies āmatched bearing and seal components so the ārotating assemblyā retains correct alignment and preload after replacement. in operation the outer bearing race ā¤is typically press-fit into the ā¤tub or hub while the inner race fits the drive shaft; the āseal lip rides against the rotating face to exclude fluid. Bearings⣠transfer dynamic loads and react to imbalance and shock loadsā during spin cycles, while the sealā protects the lubricant and bearing surfaces from ā¢corrosion and contamination that accelerate wear.
Mechanical requirements for a reliable repairā include correct seating (press fit) of races, restoration āof the designed axial clearance or preloadand āreplenishment of the specified ābearing grease.During service, clean mating surfaces, inspectā the hub boreā for ā£out-of-round conditions, āand⢠replace any corroded fasteners or shear ā¤rings that affect bearing ā¤retention. Follow⢠torque values and assembly procedures from⢠the āmachine’s service manual because improper preload or a damaged seal lip will lead to noise, vibration, lubricant lossor leak-thru. Practical checks after installation include verifying minimalā radial runout, confirming the seal sits flush without twistingand running āa short high-speed spin to confirm absence ā£of grinding noise or visible leakage.
- Common āfailure symptoms: grinding or rumbling during spin, visible water on the āfloor ā¢near the front or rear of ā¢the tuband excessive drum wobbleā or vibration.
- Installation checks: confirm hub bore and shaft dimensions match the replacement parts, ā¤ensure races are fully seated with⣠an arbor press or ā¢approved⣠toolingand replace ā¢grease with the manufacturer-specified ālubricant.

How the W10435302 Whirlpool Washer āSeal and Bearing Kit Operates Within the Tub, Spindle and Drive Assembly
The W10435302 Whirlpool Washer Seal⢠and ā£Bearing Kit replaces the radial bearings ā£and primary tub seal that form the rotating support and fluid ābarrier at the inner tub-to-spindle junction. āIn the assembly, bearingsā are⢠pressed into the outer tub hub āand ride on the splinedā spindle āor ā¢shaft, providingā concentric support āfor the inner tub āwhile transmitting torque from the drive⤠system. The seal mounts at the interface between the hub and theā tub āto exclude wash waterā and detergent from the bearing cavity and to retain grease. Correct fitment relies on interference tolerances: bearings mustā be installed to⣠full depth ā¤in theā hub bore and the seal must engage the shaft lip with proper preloadā to prevent leakage⢠without excessive ā¢friction.
- Common failure indicators: grinding or ā¤rumbling noises during ā¢spin, axial play or wobble in theā inner tub, visible grease orā water at the bottom of the washer.
- Service considerations: replace bearingsā and seal ātogether, use a press or appropriate driver ā¢to avoid ārace damageand verify spindle nut torque and hub alignment on reassembly.
During agitation and high-speed spin the bearings absorb radial loads ā£and resist lateral forces from imbalanced loads, while the seal protects the ā£lubricant film that ensures low-friction rotation. Contaminants such as water,detergent chemicals,or metal debris ā£breach⢠the seal and⣠accelerate pitting,corrosion,and⤠lubricant breakdown; these mechanistic changes manifestā as increased drag,heat,and noise before catastrophic bearing ā¢failure. For a practical diagnostic: a technician who observes grease āon the outer tub āor hears a metallic ā¢grind āduring āspin should āremove āthe⤠hub ā£to⣠inspect the bearings and seal-if⢠either component showsā corrosion, brinellingor torn sealing ā£lips, replacement with a matched kit āand correct installationā tools restores concentricity and service life.

Common Failure Symptoms: Noise, Water Intrusion, Vibration and Drum Play Indicators
The W10435302 Whirlpool Washer Seal and Bearing Kit ā£replaces ā£the bearing set and inner tub seal that locate and seal āthe inner wash drumā on ā¢compatible Whirlpool washer ā¤tubs.Bearings carry the⢠radial and āaxial loads ā£from the drum and transfer ā£them to⤠the drive shaft and outer housing; the inner seal separates the bearing cavity from the wash chamber to preventā water intrusion⣠and grease loss. When bearings begin to degrade,⣠their rolling elements and races develop increased friction and clearance, producing distinct mechanical symptoms during ā¤agitation andā highāspeed spin. Verify compatibility with the machine’s model number and the āOEM parts sheet before installation as the kit is engineered to match specific shaft diameters, press āfitsand seal ā¢lipsā used in the factory assembly.
- Loud rumbling or⤠grinding during spin that changes with drum speed or loadā position
- Water puddling⣠under the washer or visible grease/rust on the cabinet floor
- Pronounced drum wobble or axial ā£play⣠when pushing the inner tub by hand
- Intermittent squeak orā scraping that⣠correlates with drum rotation
- Metal shavings or contaminated grease visible at the ābearing mating ā£surfaces
Technicians confirm bearing/seal āfailure by handārotating the drum to feel roughness or by measuring drum play; axial or radial displacement on ā£the āorderā of a⤠few millimetersā (commonly greater than 3-5 mm) or audible roughness are practical thresholds indicating replacement. During ā¢service, inspect the āhub and āouter raceā seating for corrosion or scoring as severely damaged āhubs āmay require replacement āalong with the W10435302 kit; reassembly requires correct press fit, specified bearing greaseand proper torque on the retaining hardware to restore alignment and service ā¢life.ā Replacing the seal and bearings⤠eliminates the path for waterā intrusion and restores bearing preload and drum⣠concentricity when performedā with the correct tools and ā¤installation procedures.

Compatibility, Replacement Considerations and Diagnostic/Installation Procedures for the W10435302 Whirlpool āWasher Seal and Bearing Kit
The W10435302 Whirlpool Washer Seal⣠and Bearing Kit is a service-level assembly thatā replaces⢠the rotating bearing and ā£the radial lip seal ā¢that protects it from water intrusion. In a⣠typical āwasher, the bearing⢠supports the inner tub or wash plate on the ādrive shaft and the seal prevents⢠washā water and detergent fromā reaching the bearing race; once the seal breaches, corrosion and contamination accelerate bearing wear. Confirm compatibility by matching the ā£tub casting bore, ābearing āouter diameterand seal thickness to the existing components – the kit is intended for ātubs with a pressed-in bearing arrangement. Examples of appropriateā contextsā include machinesā showing ārotational noise combined with water leaks at the baseor tubs exhibiting excessive radial play after extended service life; in āthese cases replacing both the bearing and seal together restores the intended ā¤interfaceā and sealing function.
- Common diagnostic signs: grinding or rumbling during spin, lateral wobble ofā the inner tub, visible water at the cabinet baseand roughness when ā¢rotating the ātub ā¤by hand.
- Pre-replacement checks: verify tub bore diameter, measure shaft runout, inspect shaft surface for scoringand confirm that āthe replacement kit ā¤matches the hub/bearing press-fit geometry.
- Required tooling/handling: hydraulic or arbor press, ābearing drivers⤠that contact the outer race, ācirclip pliersand heat sources for hub retention if interference⢠fit is tight.
| Item | Description |
|---|---|
| Bearing type | Sealedā radial bearing designed for press-fit into the tub casting; outer race must be driven without loading⤠the inner race. |
| Seal type | Elastomeric lip seal ā¤with metal case-install with the ⤠lipā facing the water and the metal case toward ā¢the bearing side. |
| Fit/Installation | Press-fit tolerances require correct driver size and even pressure; use a press to seat the bearing squarely and avoid impacting the inner ā£race. |
Diagnostic and installation procedures prioritize preserving component tolerances and preventing contamination: first reproduce symptoms by hand-rotating and loading⤠the tub to confirm bearing roughness ā£and measure⣠any radialā play ā¤(play greater than approximately 0.5 mm warrants replacement). ā¢During ā¤removal, support the ātub āto prevent distortion, use a āpress or⤠appropriate driver to extract the old ābearing āfrom the bore,ā inspect the āshaft and hub for scoring⢠or fretting (replace or re-machine⣠if surface finish is compromised), then install the new bearing ā£using⣠a driver against the outer race only.whenā seating the seal, ensureā the sealing lip orientation is correct and that the seal is fully seated to the boreā face; after reassembly run the washer at low speed to ā£check⢠for noise and leaksā before ā£returning to normal service. Follow manufacturer service manuals for disassembly sequences and final torque or clampā specifications to maintain alignment and prevent premature failure.
