I don't know if anyone remembers (or gives a flying crap), but a while back I posted a thread about a mysterious spattering of oil on my tailgate. I crawled all under my L and couldn't find any leaks anywhere, but there were spots on my spare and on my fuel tank (along with the obvious ones on my tailgate and bumper). After consulting the masses and not really coming up with too much, I just figured I'd ride it out and see what happens. Well, it happened. Over the past few days, the spots have been getting worse and worse. I finally got back up under the truck and discovered that the seal where the driveshaft enters the rear of the "pumpkin" is shot. Fluid hasn't puddled on the floor, yet, but it sure makes a mess when I'm going down the road. Anyway, if you ever come across spots on the tailgate and are baffled, keep an eye on the driveshaft/rear end seal. Mine showed NO signs of leaking early on...but when it let go, it did it fast.

The truck is dirty so the spots show up. I want my tech to be able to see them. Glad I snapped some pics, though..it rained shortly after these were taken, erasing all evidence.

Duck,

Thanks for posting that, it's good information to know. I'll keep an eye on mine.

DUCK01,

I was having the same problem as you. I noticed spotting on the tailgate and some light spotting on the ground. Truck gets driven very hard.

I had the rear pinion seal, lubricant, and inspection cover gasket replaced about a month ago. First real problem that I have had with this truck.

My F-150 4X4 Tail Gate gets dirty too, but the grease glaze is caused by a combination of road crud/areodynamics. You see, my rear end is wet too from input shaft seal failure. How difficult is it for a do-it-yourselfer to change the seal? Are there any difficult steps? Are there any special tools needed, such as a 1000 pound impact wrench. I have limited-slip gears on my vehicle. Does FOMOCO hold a patent and a sales leverage on the gear lube for this rear?

 

Thanks for the heads up! Hopefully this truck will be fairly reliable!

Whoah - that's amazing. Thanks for sharing your experience and what to look out for. Hope you get your truck back on the road soon!
