WP9703445 KitchenAid Stand Mixer Thrust Bearing – Fix Your Mixer That's Leaking Oil, Making Noise, or Has a Wobbly Head

The essential fix for a KitchenAid stand mixer that's leaking oil, making grinding or clicking noises, has a wobbly or loose mixer head, or vibrates excessively during use. The thrust bearing is a critical component inside the mixer's gear housing — it supports the planetary gear assembly and allows smooth, quiet rotation of the beater shaft. Over time, this bearing wears out from regular use, causing oil to leak from the mixer head onto your ingredients, grinding or clicking sounds during operation, excessive vibration, or a loose/wobbly feeling in the mixer head. If you see oil dripping from your mixer, hear unusual noises, or notice the beater wobbling more than normal — a worn thrust bearing is the most common cause. This genuine OEM KitchenAid/Whirlpool part directly replaces 9703445. Fits KitchenAid Artisan, Professional, Classic, and other tilt-head and bowl-lift stand mixer models. Moderate 45–60 minute DIY repair that restores smooth, quiet operation and extends the life of your mixer for years to come.
