Engine/Transmission (1998.5 - 2002) No 4 Wheel Help

:--) :--) Oo. I HAVE A 01 3/4 TON TCD AND THE FRONT WHEELS WONT LOCK IN WHEN IN 4X4 ANY KNOW ANY THING ABOUT THIS

I had the vacuum actuator go out on me. It is the piece on he passenger side of the axle on the back. To test to see if this is the problem remove the four bolts that hold it on. Oil will come out but it is less than one quart. remove the two vacuum lines and the 4x4 light connector. Now that you have the piece in your hands put your finger over one of the holes and try to slide the fork. If you can and hear air leaking this is your problem.

What exactly does this fork do? is the axle 2 piece right there?

no 4wd

Probably the vacuum switch on top of the transfer case. They tend to get stuck if you don't use 4wd for a while. Easy to change, located on the top left side.
