99nbs transfer case and front diff seal question, help
My 99 nbs z71 has started leaking pretty good in 2 places. My transfer case, is leaking on both outputs , seals? Also my front diff is leaking out the output seal on my drivers side. I have a manual transfer case. I'm asking for a few tips and/or ideas because I've never done these before, thanks. Can I do both with them in the truck? Do I need a special pulled?

The T-case rear seal is easy, just pull it off and tap a new one on. My front seal is different than yours as I have Autotrack.
The drivers side front diff can also be done in the truck. Youll need to remove the CV shaft, sway bar end link and use a slide hammer with the "paw" attachment. I had to use the slide from a blind hole puller as its much shorter and will fit in the space you have. Just attach the paw, and slider and pop it out, pull the seal and reverse. Make sure to get the GM "updated" seal and not use the cheap *** ones from parts stores. It will leak again if you do.
