Hello Neptune Owners!
You can purchase the Maytag Neptune bearings and 12002022 seal kit at www.neptunebearing.com and also you can rent the Tony Tool, too. The Tony Tool was designed specifically for changing the Neptune bearings and comes with a DVD that shows you how to disassemble Neptune, replace bearings and install the seal kit.
Don't spend $450 for a new outer tub! Just replace the bearings and seal.
In addition, you need to check to see if your machine has the defective door latch wax motor, 12002535, before your control board gets damaged. All Neptunes that have the wax motor will fail. See www.neptunewaxmotor.com for info.
