Understanding the Problem
What this kit is and when you need it: An LG washer tub bearing and seal kit replaces the bearings and rubber seals that allow the inner tub (drum) to spin smoothly on the outer tub/shaft. When bearings or seals fail you typically get grinding/rattling noises, excessive vibration/wobble during spin, or water leaking from the front/bottom of the machine. Step-by-step diagnostic & repair steps: 1) Verify symptoms: Run an empty spin cycle and listen. Grinding, metallic screeching, or a knocking that increases with spin speed strongly suggest bearing damage. Visible water/drips or grease around the front seal/tub seam indicates seal failure. 2) Safety & prep: Unplug the washer and shut off water. Move the washer to a clear workspace or pull it forward. Have towels/bucket ready to catch any residual water. 3) Identify your model and get the right kit: Check the washer model number (on the door frame or rear panel). Bearing/seal kits are model-specific—order an OEM or high-quality aftermarket kit that matches your model. 4) Tools & supplies: Socket/ratchet set, nut drivers, flat & Phillips screwdrivers, adjustable wrench, rubber mallet, bearing puller or hydraulic press, bearing driver set or correctly sized sockets, snap ring pliers, seal driver or PVC pipe sleeve, penetrating oil, rags, and safety glasses. Also have RTV sealant if the model requires it. 5) Access the tub and inspect: Remove top/back/front panels per your model. Remove agitator or inner tub components if top-loader; for front-loaders remove door boot/retainer and front panel. Manually spin the drum and check for radial play (wobble) and roughness. Excessive play or rough rotation confirms bearing replacement. 6) Disassembly to the hub/shaft: Drain any water. Remove drive belt and motor (if needed), remove pulley/clutch assembly from the tub shaft, unbolt the outer tub/housing to expose the tub shaft/hub. For top-loaders you may need to separate the inner from outer tub. 7) Remove the old bearings & seals: Use a bearing puller or press to drive out the inner and outer bearings and remove the old rubber seals. Keep track of any shims/retaining rings. Clean the shaft and bore thoroughly, removing grease and corrosion. Inspect the shaft/hub for scoring or wear—deep grooves require shaft/hub replacement. 8) Install new bearings & seals correctly: Lightly lubricate the bearing OD and bore with appropriate assembly grease if recommended. Press bearings straight in using a press or driver that bears on the outer race (do not hit the inner race). Install new seals with a seal driver, ensuring they are flush and not cocked. Reinstall any shims/retainers exactly as removed. 9) Reassemble: Reinstall the tub housing, pulley, motor/belt, and all panels. Torque fasteners to spec. Reconnect water and power. 10) Test: Run a no-load spin and then a small load test. Listen for noise and watch for wobble or leaks. Re-check fasteners and seal area after initial test cycles. Practical “how-to” tips: If you lack a hydraulic press, many local machine shops or some parts stores will press bearings for you for a modest fee. Use a bearing driver or a sleeve that contacts only the outer race when installing. Never hammer a bearing into place by contacting the inner race. Safety note: Always unplug the washer and shut off water before starting. Bearings are heavy-duty parts and removal/installation requires significant force and proper tools—if you don’t have a press/puller or are unsure, hire a technician to avoid damaging the tub or injuring yourself.
Common Symptoms
Loud grinding or squealing during spin, drum wobble or off-balance vibration, grease or water leaking from the tub/door area, and poor spin performance or repeated unbalanced errors.
Common Causes
- Normal wear of bearings over time from friction and load
- Water intrusion past a failed seal causing corrosion and bearing failure
- Bent or scored shaft/hub from previous impacts or improper installation
- Overloading the washer repeatedly accelerating wear

Helpful Repair Tip
Confirm faulty bearings by grabbing the drum edge and rocking it; more than 1/4" radial play or a rough/grinding feel when spinning by hand means the bearings need replacement. Also inspect for brown/black grease or rust at the front seal—this indicates seal failure.
Frequently Asked Questions
Can I replace just the seals and keep the old bearings?
Sometimes you can if the bearings spin smoothly with no play or noise and the only failure is a dry/rotten-looking seal. However, once a seal has failed it often allows water into the bearings and accelerates wear—best practice is to replace bearings and seals together to avoid doing the job twice.
How long does a tub bearing and seal replacement take and can I do it myself?
An experienced DIYer with the right tools (bearing puller or press, drivers, service manual) can complete the job in 2–4 hours. If you don’t have a press/puller or are uncomfortable disassembling the tub and motor, plan for a professional repair—the labor is intensive and incorrect installation can cause rapid re-failure.
