Bought the truck brand new. Problem is that I only used the 4x4 a few times and never really used much since. It's been at least 3 years or more since I've used it. Now nothing works. Would like to use it again but not sure where to begin. Vacuum hoses cracked? Need new sensor? Need new fuse? Suggestions would be greatly appreciated.....Thx

 

i would start by checking the vaccum solanoid its right behind the batter see if you are getting vaccum to it and if you are check to see if its working (when the truck is running vaccum should pass through the solanoid and when you put it in 4x4 vaccum should stop at it) if everything is working there i would then look to see if your transfercase is locking in

 

Thx..... I will try that....
