Understanding the Problem
What W10435302 is and why it's used: W10435302 is a tub bearing and seal kit (sometimes sold with an installation tool) for many Whirlpool/Maytag top‑load washers (Cabrio, Bravos, Oasis and similar). The bearing supports the washer’s inner tub on the drive shaft; the seal keeps water out of the bearing area. When the bearing or seal fails, you’ll get loud grinding/rumbling noises, excessive vibration or water leaks. Step‑by‑step diagnostic and repair instructions: 1) Confirm the symptom: Run a spin cycle and listen for a loud rumbling/grinding noise (often described as an airplane taking off) or feel heavy vibration and wobble. Check the floor under the washer for water (leaks) and inspect around the base for grease/oily residue. 2) Check for play in the basket: With power off and water hoses disconnected, manually grab the inner tub and rock it front‑to‑back and side‑to‑side. Excessive play (more than a small amount) means worn bearings or a worn drive block/bearing interface. 3) Inspect the drive block/agitation assembly (for Cabrio/Oasis style): Remove the agitator and look for wear on the drive block; a broken drive block can mimic bearing symptoms. 4) Remove the cabinet/top and control (follow your model’s service manual) and disconnect power. Remove the washer lid/agitator and the outer cabinet as required to access the inner tub. 5) Drain and remove the inner tub: Disconnect hoses, remove the basket retaining nut/bolt, pull the inner tub assembly off the drive shaft. This may require two people — the tub is heavy. 6) Remove the old bearing and seal: Use a bearing puller or carefully chisel/drive out the race and bearing from the tub hub. Clean the hub bore of rust and old sealant. Remove the old tub seal from the hub. 7) Prepare the new parts and tool: The W10435302 kit contains bearings, seals and sometimes the installation sleeves. If your kit doesn’t include a specific driver, use the OEM bearing installation tool (W10447783 or AP5325072) to press parts in straight. 8) Install the new bearing(s): Using the correct sized driver, press the bearing into the tub hub squarely. Do not press on the inner race — press only on the outer race (or use the kit tool designed for the job). Press until fully seated. 9) Install the tub seal(s): Seat the new seal with light taps using a block so it goes in evenly. Apply a thin film of compatible grease to the seal lip if recommended by the kit instructions. 10) Reassemble: Reinstall the inner tub on the drive shaft, torque the basket nut to spec (check your model’s manual), reconnect hoses and wiring, reassemble the cabinet and control, reconnect water and power. 11) Test: Run a spin/drain cycle empty to confirm noise is gone, no wobble, and there are no leaks. Practical repair notes: Having the bearing installation tool (W10435302 kit or W10447783/AP5325033 tool) makes the job much easier and prevents damaging the new bearing/seal. If the drive shaft or hub is scored or damaged, the shaft or hub may also need replacement. Safety note: Always unplug the washer and shut off water before starting. The inner tub and related components are heavy — use proper lifting technique or a helper. If you’re unsure about pressing bearings straight, consider a shop press or professional help.
Common Symptoms
Loud rumbling or grinding during spin (often described as an airplane), washer vibrates or wobbles heavily, water leaking from bottom of washer, grease/oil at base, rough feel when spinning inner tub by hand.
Common Causes
- Bearing wear from normal use (age and miles)
- Water intrusion from failed tub seal causing corrosion of the bearing
- Overloading the washer or repeated heavy loads causing premature bearing failure

Helpful Repair Tip
Quick confirmation: With power off, try to spin the inner tub by hand. If you hear grinding or feel roughness during rotation, or if the tub has noticeable lateral play, the bearings are bad. Also check the base area for oily residue — that usually means the tub seal has failed and allowed water into the bearings.
Frequently Asked Questions
Will replacing the bearings fix noisy spinning and leaking?
Yes — if the noise and leaks are caused by worn bearings and a failed tub seal, replacing both (bearing + seal kit W10435302) will fix the symptoms. Be sure to inspect the drive shaft and hub for damage; a scored hub or worn drive block may also need replacement.
Can I do this repair myself or do I need special tools?
A competent DIYer can replace these bearings, but you need the right tools: a bearing puller or chisel for removal and a proper bearing installation driver or press to seat the new bearings without damaging them. The W10435302 kit is often sold with or alongside a driver tool (W10447783). If you don’t have a press or driver, a machine shop or appliance pro can press the bearings in to avoid mistakes.
