4WD Problems....HELP

It's the strangest thing...The 4wd light wont go off....I get wheel hop around corners...but with transfer case in 4wd the front tires aren't pulling....the only thing i can figure is transfer case. Maybe someone has had this problem. I have vacuum at front axle actuator...but when I shift transfer case vacuum wont change sides. Actually I will start a new post to figure this out.

Re: 4WD Problems....HELP

Do you have a vacume diagram to show you whats supposed to do what? Somethings not right. They don't "hop" around corners in 2WD.

Re: 4WD Problems....HELP

Try the link in my signature to see if all of the lines are hooked up right. One of them may have broken or come off of the transfer case.

Re: 4WD Problems....HELP

I know something is not right...I have all the vacuum lines hooked up corectly...with a constant vacuum source at the red. When I switch the transfer case from 2wd to 4wd vacuum doesn't change at the axle. ie it stays at the yellow lines when it should be changing to green...thus not diengaging the front axle and....voila we have front wheel hop. the thing that has me confused is that in 4h or 4l i am not getting any drive to front wheels. when i put in in 4l then i get low range at rear wheels. this is what makes me think transfer case is fubar.

Re: 4WD Problems....HELP

1. by wheel hop do you mean the the steering wheel hops when you make a tight turn? very normal for when 4WD is engaged

2. My axle disco switch on the TC stopped work so I by pass it. and connect the Red hose straight to the green line. When it is off road time I pop the hood and make the swap from the red to the yellow.

3. try to rotate the front drive shaft by hand? in 2wd, in 4wd with the the front axle disconnected, in 2wd with the front axle engaged( use a vacuum pump, I'd never recommend someone get under a car while it is running)

Re: 4WD Problems....HELP

You wouldn't happen to have a locker in the front, would you??? This, if the axle was engaged, would give the effect that you describe ...even if the driveshaft wasn't locked in at the t-case.
