Grinding or rumbling noise during spin that gets louder over time.

Safety first: Unplug the appliance. This repair is complex and time-consuming.

• Confirm bearing noise: Spin the drum by hand with the unit off. A rough, growling sound or side-to-side play indicates bearing wear.
• Check for leaks at rear: Look for rust streaks or water trails at the rear tub bearing area, indicating seal failure.
• Plan repair: Bearing replacement typically requires removing the drum and splitting the outer tub. Many KitchenAid models use a rear tub half with integrated bearings.
• Replace tub assembly: Remove the top, front, and rear panels, disconnect motor, shocks, springs, and hoses, then lift out the tub. Split the tub and install a new rear tub half (or complete tub assembly) with bearings and seal. Inspect and replace the drum spider if corroded or cracked.
• Reassemble carefully: Refit all components, ensuring proper alignment and torque on bolts.
• Recommendation: Due to the complexity, most homeowners should have a professional perform this repair.
