Rear brakes soaked in grease/oil ?
i have a 2000 E-350 w/ thr 5.4L. It's a standard setup in the rear and i noticed a few weeks ago that my brakes were soaked in a dark greasy paste. i thought it was bearing grease but upon dissasembly i found no grease there. so i got new bearings as they were shot and put everything back together, including a diff fluid service.
initially, i thought maybe it's a seal that failed and allowed differential fluid to mix in with the grease but i found no grease so now i'm wondering ... Is the hub supposed to be packed with grease, or is it a regular sealed hub??
if it's sealed where did that oil come from?(it wasnt brake fluid)
