W10435302 Whirlpool⢠Washer Seal and Bearing Kit is a combined seal and bearing repair⣠assembly designed âfor use âin domestic â¤washing machines. The kit typically â¤includes one or âŁmore radialâ bearings andâ corresponding rubber or elastomeric seals (and sometimes⢠retaining components) âŁthat together support theâ rotating tub or shaft andâ provide a fluid-tight barrier between the bearing lubrication and the wash compartment. Asâ a mechanical âcomponent, it isâ a service part intended to restore axial and âradial support as well as sealing integrity where the⣠inner tub shaft passes⤠through the outer tub⣠or bearing housing.
Inside the appliance the âŁseal and bearing kit sits⢠at the interface â˘between the tub/drumâ and the transmission â˘or drive âspindle;⢠it transmits rotational⤠loads from âthe motor and drive system to the tub while preventingâ water and detergent âfrom entering the âbearingâ cavity.⤠the bearings carry radial and⢠axial âloads during agitation and spin â¤cycles and must maintain concentricity â˘and low âfriction, while â˘the seals must resist water, detergentand temperature cycles to protect the âbearing lubricant. âThe assembly therefore interacts directly with the drive â¤system (motor, â¤pulley or direct drive coupling), âthe tub⤠and basket, the âbearing housing or hub, âŁand the washer suspension; improper fit, wearorâ seal failure affects alignment, vibration levels, noiseand the machine’s ability to contain wash water.
In this âarticle you will âfind a technical overview of â˘the W10435302 kit:â how âthe âcomponent functions, what dimensions and compatibility checks are important when confirming fit for particular washer âmodels, commonâ failure âŁsymptoms to recognize â(for example leaks, grinding or⣠rumblingâ noises, excessive vibration or wobbleand lubricant contamination), methods for diagnosing⤠bearing versus seal failure, â˘andâ practical⢠replacementâ considerations suchâ as required tooling,⣠press-fitâ and seal âorientation concerns,â cleaning âŁand inspection stepsand post-replacement âŁtesting. The focus âis on providing technicians, âengineersand appliance owners with the information needed â¤to assessâ condition, selectâ a compatible replacementand plan⣠a safe, effective repair.

Function and Role of the Tub Seal and Bearing Assembly in⢠Load Stability and Leak Prevention
The W10435302 Whirlpool Washer Seal and Bearingâ Kit â˘replaces the tub bearings and the radial lip seal that together locate and support the⢠inner wash tub while keeping wash fluid out of⤠the bearing cavity. The bearing components provide the radial and limitedâ axial support needed to maintain concentric â˘rotation⣠of the tub on the drive shaft, while the seal uses a molded elastomer lip â˘to form a dynamic â¤barrier around the rotating interface. In service⤠practice, â˘a â˘failed seal allows âwater and detergent into the grease-filled bearings,â accelerating corrosion and race wear; similarly, bearingâ wearâ increases shaft runout andâ can âdeform⢠theâ sealing surface, so â˘replacingâ both â¤elements as âŁa matched kitâ restoresâ the design clearance and operating behavior.
The assembly’s primary role in loadâ stability is to âcontrol radial runout and⢠lateral⢠play so that unbalanced loads âare transferred to the âsuspension and cabinet rather âthan to the bearing faces; increased play or worn races causes vibration, elevated bearing temperaturesand uneven stress on âthe tub⢠and â¤spider. Leak prevention depends on correctâ press-fit seating, undamaged sealing lipsand clean âbearing grease – practical inspection â˘and service actions â¤include checking for lateral shaft play, visual signs of greaseâ contamination in the tub sump, scoring⤠on the shaft or housingandâ confirming the⣠seal lip rides⢠on an undamaged counterface. Replacing the worn components with the W10435302 kit and â˘following proper press-fit and seating â˘procedures restores tolerances and reducesâ the likelihood of recurring âleaks or premature bearing failure.
- Common service indicators: âaudible rumbling during⤠spin,lateral tub⤠play,visible â¤grease in the sump,or water leaking at the rear âof the⣠tub.

How the W10435302 Whirlpool washer⤠Seal and âBearing Kit Integrates with the Inner⤠Tub, Drive Shaftand Bearing Housing
W10435302 â˘Whirlpool Washer Sealâ and Bearing⤠Kit interfaces directly âwith the â˘inner tub â¤flange, the â˘drive shaftand the bearing⢠housing to⤠restore âtheâ mechanical seal and rotational support lost when bearings or seals fail. The bearing cups are pressed into the bearing housing which is retained by â¤the inner âŁtub flange; â¤the drive shaft passes through âtheâ inner bearingâ and rides on the inner⢠race while the outer âŁrace is supported by the housing. The seal in the kit locates against the âinner tub flange and the outer edge of the bearingâ housing,creating aâ lip contact thatâ prevents wash â¤water from entering âŁthe bearing cavity. During high-speed spin cycles âthe bearings carry radial and a small proportion of axial â˘loadsâ from the tub; proper press-fit, âŁshaft surface conditionand⣠correct seal orientation are⢠required to maintain concentricity and prevent premature wear or leakage.
Technically, integration requires attention to â¤fit,â alignmentandâ surface condition: the outer race must beâ evenly âseated in the housing to avoid eccentric loading,â and the drive âshaft journalâ must be smooth and⤠within original diameter â˘tolerances so the inner bearing race runs â¤true. After installing the kit technicians should verify smooth free-spin without axial play and check âŁfor âseal lip contact with âŁthe shaft at â¤rest and under rotation to ensure no âwater ingress. practical checks include inspecting the inner tub flange for ovality, confirming the bearing housing bore is not corrodedand using a bearing driver toâ achieve âan even interference âfit; when these conditions are met the W10435302 kit re-establishes both the rotational support and⤠theâ fluid barrier neededâ forâ reliable operation.
- Common signs that indicate the kit is needed:â grinding noise âduring spin, tub wobble, oil or grease contamination in the wash tuband visible water leakage atâ the tub-housing â¤interface.

Common failure Symptoms and Diagnostic Procedures âfor Wornâ seals and Bearings
The primary service function of the W10435302 Whirlpool⢠Washer Seal and Bearing kit is to restore the â˘watertight seal around the tub shaft and provide low-friction radial and thrust â˘support for the inner tub. Typical failure behaviors include progressive metallic grinding during high-speed spin, intermittent or⣠continuous water leakage at the front of the â˘tuband increased vibration or tub wobbleâ caused by â¤bearing wear or a collapsed sealâ lip.This kit is intended as a direct replacement for the common factory-installed seals and⣠bearings used⣠on many Whirlpool direct-drive top-load washers; compatibility should be âverified against⤠the washer’s model number and parts diagram before installation. Practical examples include a âwasher that leaks only after a â¤high-speedâ spin (indicative of âa compromised lipâ seal) versus one that leaks at idle as well (suggesting a⣠heavily corroded âbearing race allowing water migration).
- Unusual â¤grinding or rumbling at spin speed
- Visible water escape or grease staining at the front tub âseam
- Excessive tub wobble or lateral âŁplay when rotating⣠the inner tub by hand
- Intermittent noise that changes with load distribution
Diagnostic procedure should start with non-destructive checks: rotate the inner tubâ by hand to feel âfor roughnessand apply a vertical and lateral load to detectâ axialâ orâ radial play. Use a âdial indicator âto quantify â radial ârunout and⣠axial play; values greater âŁthan about 0.5 mm⢠radial runoutâ orâ axial play exceeding 1 mm (0.04â in) are commonly considered out of tolerance and justify replacement. If you remove â¤the tub, inspect⢠the seal lip for scoring⣠or hardening, check the inner and outerâ bearing races for pitting âor⣠vaultingand confirm the retaining ring and⢠spacer dimensions match âthe replacement kit. When a âŁbearing and seal replacement is performed, âŁclean mating âsurfaces thoroughly, verify shaft and housing tolerancesand torque fasteners to the âmanufacturer’s specification to prevent premature failure from âŁmisalignment or distortion.

Replacement Considerations, âModel Compatibilityand Service Installation Guidelines for⢠the âW10435302 Whirlpool Washer Seal âand Bearing Kit
The W10435302⣠Whirlpool â¤Washer Seal and Bearing Kit provides the â¤rotating⣠support and fluid containment for the washer tub assembly: the bearings carry radial and⤠axial loads from the â˘inner drum while the mating seal âŁprevents â¤transmission of wash water into the bearing cavity. In typical â¤service scenarios the bearings are⤠interference-fit âinto the outer⣠housing and onto the⢠shaftand the seal is aâ sprung-lip elastomer that rides against the rotating shaft⢠or hub. Failure â¤modes âinclude grease washout and corrosion from a leaking âseal,â audible â¤rumble from brinelling or race damageand excessive drum play from âworn âbore or shaft wear; âreplacing both the bearings and the sealâ together restores alignment and the protective barrier⢠that â˘preservesâ bearingâ lubrication â˘and life.
Before⣠installing the W10435302 Whirlpool â˘Washer Seal and Bearing Kit â˘verify physical compatibility with the washer model,housing âbore condition,and shaft geometry rather than relying⣠solely on part number cross-references. during service use a proper bearing press or arbor and⤠a dedicatedâ seal driver to seatâ components squarely; striking âbearings orâ seals⣠with unsupported force risks brinelling the races or distortingâ the seal lip. After⤠assembly,â check âshaft runout âand torque the retaining fasteners to the manufacturer’s âspecification, applyâ appropriate high-temperature bearing â¤grease⣠if the design requiresand perform a wet spin test to confirm there â˘are no leaks âor âŁabnormal noises. â¤For seized assemblies, controlled âheating of the housing â˘or⤠use of a puller is preferable to destructive hammering to⤠avoid housing damage and misalignment.
- Common symptoms indicatingâ replacement: persistent leak at the tub, growling noise under âloadand excessive drumâ wobble.
- Compatibility checks: verify bore and shaft dimensions, housing conditionand original equipment drawings when available.
- Installation⢠precautions:⤠use a press and seal driver, avoid deforming theâ seal lipand verify runoutâ before reassembly.
