so when i turn on my 4x4 and drive it makes a bad KLUNK! noise and the 4x4 drops out and leaves me spinning in two wheel drive.
any suggestions?

 

check and see if your front driveshaft spins in 4wd (do a brake stand in the dirt or something and get a buddy to look under) if it is spinning it's something in your diff thats broken, if it dont spin probably the chain or gear in your transfercase is broke.... time to make a trip to the auto wrekers for some parts

 

ok thx I'll give that a try.
