I have a 2001 Ford f150 SuperCrew 4wd that I tow with. I was bringing the Jeep back home and at some point in my trip, both rear axle seals blew out. I had rear end dope all over the side of the truck and the jeep. I have already replaced the seals, but I am trying to figure out what caused them both to go at the same time. Checked the vent tube, its free from any obstructions and is not clogged or stopped up. Checked the bearings, there is no play in those or noise. What was left in there when I popped the cover looked just as clean as the new I put back in. The only thing I noticed was some sludge on the axle shafts toward the seal/bearing end like the axle shaft had gotten hot, but there was none in the chunk. The truck does have 137,000 miles on it, and I could understand if one starts leaking due to age, but both at the same time just concerned me that I might have a problem besides just a failing seal. I've towed with it quite a few times over the years and never a problem other than needing a diesel under the hood. Any ideas?
