Thanks for the tip Nicmike. It was actually fairly mess free as the tubing I used was such a tight fit in the hole that nothing leaked back when filling except at the end when removing the tubing.

Yes, and if you ever have to add friction modifier, the ABS sensor hole is about the only way to do that without making a mess. If you think gear oil stinks, wait till you smell the friction modifier.

Ford's original fill for that axle was synthetic, and the service fill called for synthetic.

You have the reverse issue, where your pinion seal failed using a petroleum gear oil... which while unusual, is not unreasonable, given that Ford designed the seals for the axle to coexist with the synthetic lubricant originally specified. It could be that the seal, while perfectly compatible with synthetics, might end up swelling or reacting in some way with dino oils. There is a dizzying array of material property conflicts between seals and lubricants... makes my head spin. (e.g. Buna N rubber above 36% acrylonitrile is ok, but below 36% not ok, etc)

this info seems confusing to me, but mainly because the new seals that you would buy fit the 10.25 and 10.5 axle that would cover from around 1985(Dino oil) to the synthetic axles. So I would venture a guess that the seal failure could just because of contamination/damage when assembled, or possibly the pinion nut backed off a tad. Iíve had new pinion seals leak for about a week and than just stop for no reason.

Of course if the engineers would simply specify using ONLY unga bunga X rubber, this would all be a moot point! Counting pennies I suppose.

The petroleum-based gear oil was only in for about 10 days, now replaced with synthetic. Hopefully the leak will stop. The leak is only slight anyway.

KR wheels installed. kinda regret the 265/70r18 instead of the 275/70r18. maybe next time saved me 125 this time around. look and ride way nicer. my wife however who doesn't care at all about vehicles says it still needs bigger wheels :/ she doesn't like how much space there is between the top of the tire and the fender arch......too used to cars and minivans i think....

get a pic tomorrow

I think there's a tiny bit of rub with my 275/70 on the liner near the inside rear corner of the drivers side front wheel well. Only happens when I'm at full steering lock to the left and I hit a nice sized bump. For example, making a k turn and jumping the curb in the process. You New Yorkers know what I'm talking about...... I think I can just pull the liner back with some zip ties but with the 265/70 you shouldn't have this issue.

Hell no! Leave the vent lines on both front and rear diffs and cover the ends with screen wire or a fancy diff vent line check valve. If the vent gets clogged your diff will pressurize as you drive and the fluid heats up and cause the fluid to be forced out the axle seals (rear) or the seals in the diff housing (front). I had both front and rear driver side leaks and found both of my diff vent lines plugged with mud dauber nests. If you guys donít have mud daubers consider yourselves lucky. They wreck everything down here and thereís pretty much no way to stop the filthy little bastages! I have to put trash bags over my outboard motors and plug any holes with foil to keep them from building nests.
