This causes confusion for a lot of people. Think about it this way:

In Full-Time 4x4, you can leave the transfer case in 4x4 full time / all of the time
In Part-Time 4x4, you can only use 4x4 part of the time (when on loose/slippery surfaces).

 

Ya I definitely had it bass ackwards... lol That would make more sense anyways, because 4lo is part-time and if I'm in 4lo why would I want to only have it work until it slips.

I'm glad I look at the ask a question thread....

 

I have a 1994 Jeep Gran Cherokee Laredo with the 4x4 FULL Time, im guessing its a Quad-Trac Transmission but im not too sure. i looked in my owners manual and thats what it said but also listed a few other transmission type, by the way, my engine is a V-8. so my problem is I bought the Jeep for 1000.00, clean exterior and interior and in amazing shape but now the Jeep will not go in reverse, and has troubles shift from time to time when driving. I know my tranny is going out but im trying to make sure i buy the right transmission for my year and type of Jeep. any ideas or answers would help out a ton!! thanks guys

 

These look like the 15x8 Gamblers that jeep put on the wrongler's from the early 90's renegades to the early 00's. I purchased a set off of craigslist and put them on my xj

 

You're confused a bit. The transmission has nothing to do with 4x4. That's controlled by the transfer case (quadra-trac in your case). I'm assuming you have an automatic with that v8 so....

You have a 1994 Jeep Grand Cherokee (ZJ) with the 5.2L v8, NP249 Quadra-Trac transfer case, and 46RH 4 speed Chrysler automatic transmission.

You will need ALL of the above information to select the correct transmission that will bolt right in.

 

Gotta love when dukie takes the afternoon and answers questions from days past

 

There ya go...dukie never let's ya down! Lol!

 

X2 lol

 

Hey,
I wanted to see if anyone has the instructions or a how to on rebuilding a 1990 4.0 power steering pump. I want to make sure I put it back together correctly so I don't have to do it again.
I got it all ready to re-assemble but I can't find instructions on how to put it back together. There is a pin that I want to make sure is place correctly ect.
Thanks,
Paul.

 

i have an 86 cherokee with 2.8 and an outa trans what should be the **** points for that 3 speed auto it seems like rpms get really high before it shifts to 3rd and i just rebuild the motor and dont wanna blow it up

 

My 1990 was doing the same thing. It was the Throttle position switch on the Throttle body. The little bar that rides on the linkage some how got under the TB linkage and it was not rotating with the throttle body linkage. I bent it back into shape and put it where it was supposed to go and it started shifting correctly again. Also, look/listen for vacuum leaks, sometimes that will cause a problem too.

 

I recently traded for a '96 Cherokee with a "blown headgasket". I have always wanted a Jeep and jumped on it when I got the chance. When I removed the head I found that the headgasket was intact but the #6 cyl was missing and the connecting rod knocked a hole in the cyl wall. I belive the H.O. head is still good however and i'm now looking for an engine. My question is can I use my head on any year model 4.0 without modification (accesories, ect.).

 

Which plugs do these 4.0s prefer? Ive always been partial to NGKs but Ive seen a lot of people run Champions

 

I'm running some copper autolites..and have no problems what so ever...

I'm pretty sure the plugs that were in there were from the factory in 96 lol...so plugs, cap, rotor and wires got changed..def a difference!

 

Also there should be dummy lights that light up green for full time, giving you the green light to drive wherever. And the part time should light up orange, indicating to use caution.
