4.0L np 242 t-case

When I pull the lever into full time 4x4 nothing seems to happen, same with part time and 4 lo. The indicator light on the dash does not come on. How can I tell if it is just the indicator or if 4x4 is not working?

Thanks for any input

What year is your xj? Could be your vaccumm lines, down on the axle?

ok, just saw you have an 88'. My vaccum lines come off every once in a while. Passenger side of the front axle you can see them, 3-4 rubber lines, they come loose or fall off sometimes, check em'.

If im not mistaken (which is possible), if its a 242 from the factory then it wont have the vac-disco axle. I believe all NP/NV242's had the non-disco axle...

As far as your problem, I cant help much. I myself am dealing with a toasted np242 and am getting ready for a 231 swap. Let us know what/if you find the problem.

Quickest and easiest way to check if it is the indicator light or if you have a problem elswhere would be to have yourself or someone else stand outside the vehicle and watch to see if one of the front wheels spins when you hammer it on a slippery surface, ie loose gravel or snow and ice.

Pull it into four wheel drive part time an try turning on a dri surface slowly it will jurk and surge around corners if its working.

hell, just jack up the rear diff, put in in 4wd and see if your front tires pull you off the jack??!

Thats what I was thinking to do originally (spin the tires on loose surface). Will 4wd engage right away when I shift it (assuming it works right) or should I expect to have to travel a short distance before it engages? the reason I ask is because it always seems to need to roll a little bit to disengage. I like the idea about jacking it up in the rear also

but the only jack I have that will lift it is my hi-lift- could be dangerous, I've had it tip when on the hilift once before. oops. anyways thanks for the suggestions and i'll let you know what I find.

4x4 does work

. I put it in 4x4 full time and did some circles in a parking lot and it bounced all over. So now the problem is something with the indicator lights. Any ideas on where to look/what to check? I dont think it is bulbs because there are 4 or 5 different ones and I doubt they would all quit at once.

Thanks for the advice.
