pinion seal.

disconnect the driveshaft, take the pinion nut loose and pop the seal off, put the new one on tighten the pinion nut and put the driveshaft back.

the pinion nut needs to be tightened to a certain torque.

make sure that's where your leak is for sure and not just where it is collecting from a leak somewhere else, because that looks like where my leak builds up and drips

Mine is on it's 3rd pinion seal, and it's leaking. Mine usually doesn't leak nowhere near that bad, but it still leaks. I don't know why they do that. I wil say this though, when it's replaced this time....I'm doing it. It seems that when it's gotten replaced before was when I didn't have time to do it myself, and had to pay $250 to get it done. This time I'll make the time. How much can the damn seal cost $25-35 ?

I had to do both of my axle seals and my pinion seal back in the day....it was a PITA because of the front shafts..but the hardest part about it is getting something that will knock the seal in strait......if you dont have the seal install tools....

We looked around my ex's garage forever to find something...finally we came up with the top to a fence post the little metal cap thing...lines up perfect..

Its pretty self explainatory.....

Take the drive shaft off...... use an impact and remove the nut.....remove the seal (pry but dont mess up the surface of the front diff....)

Pop the new one in.....put the driveshaft back...

top off the fluid...

i guarantee you that it is not a pinion seal! i just fixed the same problem on my truck. it's the lower edge of the front diff seal leaking....

i'll put $50 on it

all you gotta do is pull the front driveshaft out and take off the front cover. run a small bead along the outside edge of the sealing surface and then a second bead along the inside sealing edge using Ultra Grey RTV.


whole thing takes roughly 6 to 7 hours with just hand tools

all you have to do to prove whether it's the pinion seal or not is just put it in 4HI drive around for about 10 minutes to get a little bit of friction heat built up and the temperature of the fluid up a little bit, park it, get under there with a can of brake cleaner, soak everything on the diff and driveshaft that has oil residue then wipe it down. wait an hour or two and go back and check it...


if it was the pinion seal there would be fresh oil residue all over the undercarriage and crossmembers.
