My GE WWA8350GBL WH washer is working fine - no noises, no anything to tell me it's broken other than the grease on the floor. The leaking grease started about a year ago with a couple of tiny spots I happened to catch during spring cleaning, but has gotten much worse as time has gone on.

Does anyone know where this grease might be coming from so I can repair it before it's loss does permanent damage to the machine? (Even though this machine is around 18 years old, I still love it, and I'd hate to lose it.) Is there an easy way to isolate the location of the leak without tipping the machine over? Is this a repair my husband can do (like no special tools required) or is it best to call in the pro's on this?
