Front diff is leaking a little bit. I took it up to Slaughterhouse Gulch yesterday and ran the trail in 4lo. Any idea's as to how to fix the leak. It's not much, just a drop or 4 every so often. Looks like it's leaking at the rear of the diff, where the driveshaft comes in to the u-joint

 

Mine for some reason leaks in the same spot also. I went and bought a pinion seal ($29) and when I tried to install it I found out that I did not have a socket big enough to take off the pinion nut, so mine still leaks. The pinion seal is the only reason I can think of that it leaks so try that. The pinion nut is bigger than a 1in so if you find out what size it is let me know so I can borrow one.

 

yup, pinion seal. Im on my 3rd one and it needs to be replaced again!

 

it looks like rangers have appetite for pinion seals

 

yup, mine been leaking quite awhile real slow. I just keep a eye on it and make sure it doesn't start getting constant

 

Awesome. I'm actually glad it's as easy as that, and as cheap as that as well! I'll probably just keep an eye out on it this week, fix it over the weekend, and watch it when I take it up to Chinaman Gulch over the 8th of June. It was just weird, didn't do it before I put it into 4wd, but it makes so much sense now. Just another problem area to watch on it!

 

offroad_ranger, just curious, what size socket do i need for it? And is it a pretty quick fix?

 

I would like to know what size it is to so...bump

 

mine is leaking too, noticed it on monday and today learned the hard way to never change ur front diff fluid without dropping the diff! and my diff fluid was milky green... very bad.

 

first time i did mine it was an olive drab green

 

the pinon seals are very easy to change. i did my front and rear in a few hours and im only 16. going to need a air gun for the center bolt tho.

 

Sorry for diggin up an old thread but can someone let me know exactly how to do the front pinion seal? Mine is slingin mess like crazy..and also whats the best way to change the front fluid..or should I just add to what I have lost?
Thanks

 

Should just be a matter of pulling the yoke, popping off the seal, and putting the new one back in. Changing the fluid is kinda a pain in the butt, because getting to all the bolts without dropping the diff is like pulling teeth!

 

So i guess ya had good and bad news for me lol Im sure that it has lost a good bit of fluid from that leaking seal..should I just fill it bach up? I just wonder if its a problem to mix types of fluid

 

Anybody know anything about this? I wanna do this today...whats the exact procedure for changing that seal...Im kind of un easy about just yankin out my drive shaft lol Should I take my truck to get the front fluid changed or just get as much as I can out and then refill it? I wonder if its a prob. to mix fluids
