Front Diff leaking oil..

[94Sierra4x4]

Leaking between the drivers side CV joint and the front differential.
Assuming I needed a replacement "axle seal" I bought one for each side, just going to worry about the drivers side tonight...

Any tips? Tools needed? Methods to your madness? Lemme know, thanks

No tips from me but if you could tell how you did it, that would be great!

I have a feeling it's going to be a pain in the ass, really.. Haynes manual doesn't say much of anything

Well I found this..

1994 GM 4WD

Driver side axle stub can be removed by tapping the flange with a hammer.
Replaced seal tapped back in place with hammer.

Passenger side axle removal. I unbolted the axle housing from the the differential. Replaced seal and bearing at on the outside end of axle tube.

Only trouble was with the passenger side on reassembly. After some pretty hard wacks with the hammer the gear and snap ring would not go back on the axle shaft. I had to sand the end of the shaft so the keeper would snap over the tapered edge. I managed by myself but it was pretty difficult to hold the 4wd acuator spring in place and stab the axle housing assembly back in place. Might need an extra arm for this.

My thoughts exactly.. I'm going to go do some head scratching for a bit.. maybe just fill her up for the time being. I need it to get me to work tomorrow unfortunately.

Thats pretty much how you do it. Its not that hard, a pointer that I have found to help out the axle is by using a pry bar to pry on one side of the axle and tap the other side with a mallet or hammer. When I say axle I am refering to the round axle that is in the housing of the differential. Dont be scared guys its pretty easy.

It really is that easy i just did it. Just get a jack under the CV shaft where it connects to the front diff and lower it to get at the seal. You can also just take the CV shaft out

Yeah I had a better look at it, seems like a hammer/pry bar should do the trick. I'll probably take the cv axle out.. I wonder if I could just unbolt the flange end ofthe cv and get it tied out of the way..

What size is the axle nut again?
