    I have a probably stupid yet simple question:

    Where's the fill plug on a 10-bolt front relative to the axle centerline, or relative to the bottom of the diff?

    I've got an aftermarket diff cover (originally intended for a 10b rear, and I don't have the original cover anymore...) on the front, fill plug seem rather high, and I've got too much oil in the front diff. So the heat from the motor warms up the diff oil (or the air above it), oil expands and gets out of the breather tube. Since that is extended up to the fender, I now have a nice coat of fresh gear oil on the inner fender on the driver's side :D. So I could just wait until it has pushed out enough gear oil (the drive to Denver on Tuesday nite ought to do that :laugh: ) or adjust the level, hence the question about the fill plug...thanks.

    I can probably dig up a stock front 10 bolt cover if you need on . Then plate it to protect it . As for location , eyballed with measuring tape is about 4 3/4 inches from bottom of cover to top of plug .

    Thanks, that explains it. My fill plug is an inch or so above above the axle centerline. I guess I'll get to siphon some oil out tonite...sounds like fun...

    BTW , I forgot to mention , I measured from the plug to the edge below it , which is higher than the actual center of the covers bottom .

    Hmm. Is that at the ear, or further to the center? Does 5" from the center bottom of the housing to the bottom of the fill plug sound right?
