i was driving home today everything was fine, I stopped on the street before going up my driveway and shifted into 4 wheel hi. I heard it clunk in like usual, so i try to make it up my driveway in the snow and get stuck half way up. So i apply the brakes and shift into low.Instead of moving forward or not moving at all im now sliding down my driveway backwards at a great speed after bouncing off a few trees im now stuck on the grass and 4 wheel hi and low wont work and also my back brakes are not working at all. Any suggestions on where i should start looking for problems?

 

do you have a vacume disco front end? thats probly one thing

 

if it is i didnt do it i bought it about 6 months ago has been a daily driver until now

 

ok, look under the front end, and see if the frond diff has a big box on the passenger side and it should have a vaccume line on it, that is most likely the problem if yoyu have it
