    :confused: Have searched half the morning and can't find the answer to this.

    Took a 14 bff out of a 1008 that was not leaking and a low mileage diff. Converted it to disc brakes and replaces hub seals while in it. Put the diff in my truck and had to rotate it up several degrees to get angle correct for the 8" lift and cv style shaft. No vibes everything works great but wheel seals both leak. Replaced twice since.

    My question is this: could having the front of the diff so much higher from centerline of the axle tubes be causing me to be unintentionally overfilling my diff by allowing to much fluid into the axle tubes and causing this leak??????:confused:

    did you replace the seals? If you did , did you ding the side of the hub? How does the spindal look? Sometimes you need a speedy sleeve

    that is awfully off tho since both seals are leaking seems to have to be something obvious hmm...

    Plugged vent might contribute...as the fluid heats up it'll expand and without a vent there might be enough positive pressure inside the diff to push fluid past the seals.

    Checked already, free flowing, seals have been changed twice since the initial time. no damage at seal, hub snout is perfect, bearing are tight, greased seals before install, insured I didn't scrub them across the spindle threads installing them. This is all I can think off that would cause this problem normally and nothing is differant on this axle exept the fact that it has been rotated up. This is why I was wondering if after spining it upward I may be overfilling it since the plug is up and inch or more above stock.
