Can I get a little verbal instruction from someone who has done it before. I would like to stop the dripping from the output on my xfer case. It doesn't leak that much, but I have to constantly get the oil dry out to clean it up. Its time for the drips to stop. Anyway, what do I need to know to replace the seal. Aside from pulling the drive shaft. Is there any special technique to removing the old one, and as well putting in the new one? Any advice would be appreciated.
Thanks,
Greg
Don't look at me, I'm just waiting to see what someone says. :) Mine started to drip a bit but the doc just gave me some pills and.. well.. er.. nevermind.
The only bit I remember when talking to the service guru that did my last seal was that you wanted to make sure it got driven in straight and not kinked. He used a big ass socket to drive the seal in. He just used a slide hammer with claw to rip the old one out.
Remove the drive shaft. Remove the bolt that holds the output shaft and collar in place (make sure the Jeep is in gear). Remove the seal with a seal puller or a two-arm puller, depending on transfer case. Clean around where you pulled the old seal out. Apply a thin coat of RTV to the outside rim (metal part) of the seal. Pound the seal in place with either a seal driver or a piece of pipe, again depending on transfer case. Re-install other components. Torque per specifications.

Thank you.

Chances are good that the bushing in front of that seal and the bearing in front of that are worn too. If your replacement seal doesn't do the trick, more extensive repair is required. Keep fingers crossed that this is not the case.

The question is 'why' did it fail? You are fixing the symptoms of a vibration issue or a worn out output bushing or bearing. A bad U-joint is one cause.

86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail > Can I get a little verbal instruction from someone who has done itWell one can always hope for the best. I have seen fishing line, grass or just dirt take out this kind of seal. When you're looking for causes, the condition of the yoke, where the seal rides on it, should not be overlooked. Sometimes they will have a groove in them, that can be cleaned up with emery paper. Sometimes not. The bearing you are talking about probably requires transfer case disassembly to get at, but otherwise it should not be too bad. The bushing "should" be pressed in at a machine shop, or at least by someone with a press and a good eye.
