I have a 99 Jimmy with stock everything right now. My 4 wheel drive is not engaging and I know my transfer case and front differential is leaking. Is that what is preventing my 4 wheel drive from engaging? they are slow leaks. Also I am looking to lift it about 2 in, find a brush guard, and more is definately going to pop into my mind. Any suggestions on how to/what to do/ so on would be much appreciated. The catch is right now I am a broke college student who is looking to prep this so when I am able to get another vehicle it won't be long until this is ready to become an off-road toy. So if you could please help. I am pretty handy in my ability to work on it by myself or with a buddy.
