4x4 97 ranger question
So while i was changing my fuel filler hose today, i thought it might be good to check and see if my 4x4 really works in my new truck. I jacked the thing up (all 4 tires off the ground) put it into 4x4 hi and lo, and only the back 2 tires spun. So i let it down, drove it around the block to see if that helped, jacked it back up, and still... only back 2 tires spin. I got out to look at the front 2 tires, and the passenger side one was making a clicking noise, and if i pushed it, it felt like it wanted to spin. The driver side tires i got nothing...
So do i just need to try my truck in some mud and see if my front tires spin or???
auto hubs, push button 4x4.
Also this truck has 200k miles on it, and i dont know if the 4x4 has ever really been used or not...
