front axle seal
heya
pretty easy to change an oil seal in my F250 4x4? any tips/suggestions? i have a picture, but don't have it posted, i can if needed. i see the diff oil coming out of the axle, just where the axle comes out of the housing.
thanks!

Its a PIA. The diff has to come out and new seals installed. Of course the axles have to come out first...Time to do ball joints and all seals also. If you are not a torque wrench mechanic you may have a mechanic buddy do it....Ask away!

yup monster, that's where.
and hey... just before i bought it, a lube-it filled the case. i wonder if they overfilled them! If that's the cause, will it go away, or did it ruin the seal now? thanks!
and hey... i hope i don't freak you out, is that a crack on yours? about 3" up and 1" to the left of your arrow?

Actually the seal is brand new when I did ball joints and u-joints on the drive axle and year ago. It's considered a "dust shield". It does not completely seal the back of the drive axle and the axle tube. It is possible for fluid to leak out (and fluid to get in) this seal especially if you are on an angle (or in deep water). Over filling that diff can cause the fluid to leak out these seals as well. If the seal looks to be in good shape then I wouldn't bother replacing it. You can even run without it and not have any issue if you mainly stick to roads.
To replace it you need to: Pull off the wheel, pull off the locking hub, pull off the caliper and mounting bracket, pull off the wheel hub, pull off the lock clip and various shims, then pull out the axle. The seal slides off the back side and a new one can be put on. Reassemble is reverse of removal.

Actually I didn't even think about mentioning seals that are part of the gear kit! 
I was trying to say more what this seal was in the pic. If you have a presitant leak then it's not because of this seal. Like RAMBOv10 said it's in further.

thanks guys. The time it really leaked the most, was right after i tested the 4 wheel drive.
Hey Monster... the crack i was reffering to in yours, that steve sees too, is not on your seal, it's on your axle housing, on top. do you see it in the photo?

As stated by several other posters, check the axle vents. Those internal seals almost never fail. Also, if A-lube or whoever they are used a pressurized filling system, it is possible to overpressure the differential housing and force oil out the seals.
I have been working with the SD 4x4's a long time and I have seen very few of these seals that actually needed replacing.
