Wash load came out with rust colored streaks that looked like grease stains. I found a trace of waxy brown gunk below the wash plate. There was also some water inside the u-joint and the o-ring showed signs of failure. The outer suface of the stainless steel tub was covered with the waxy gunk. I used grill cleaner and steam to get it clean. The plastic tub which I did not remove was clean except for some mildew at the top.
I bought the u-joint kit, which obviously need replacing.
Before I install it, can anyone tell me where the gunk came from? If lubricant came up the drive shaft, I would think that water would get out. There's no evidence of a leak below the washer. Is there lube sealed in the u-joint?
