Leaking transfercase

I just bought an 85' CJ-7 and the pinion seals have all just started leaking especially the ones on the transfer case. What would suddenly cause this. It wasn't leaking when I bought it. Later on after I drove it on the highway for an hour, (while in two wheel drive) there is oil everywhere. The jeep was owned by a lady in Vancouver, (where the climat is very wet, and here it is very, very dry). The jeep was driven here and then parked for over a year before I bought it. Could all of the pinion seals have dried out.
What is the best way to remove pinion seals other than prying them out with a screw driver?
The transfer case being the worst offender, could it have over pressured from a plugged vent?
If so how do I check this vent being in its poor location?

Hope someone can help? Thanx!

It's a Jeep thing...my wife doesn't understand!

Re: Leaking transfercase

did you change your gear oil or start running synthetic?
seals do dry out sometimes when just sitting, i use screwdriver handled pry bar thingy to get seals out. [img]/wwwthreads_images/icons/smile.gif[/img]

Re: Leaking transfercase

all it takes is one good oil leak under the jeep and the wind scatters the crap everywhere, even up on the back window! I'd clean everything up with a pressure washer and drive it around for a few minutes then inspect it immediately.
I use the same seal remover tool, try not to bend the seals up too much so you can read any numbers off them.

Re: Leaking transfercase

I use an Ice pick to make a hole in the seal, then use a dent puller with a screw in it to pull them out.Works on all ones I've had fits with, and it (most of the time) keeps the seal in one piece making it easier for the parts person to find the part#..
