maybe it could be tha chain, because the transfer start to vibrate when I increase the speed on jack stands and the sound is worse. what else should I check???????????????????????????

Nop! they are OK, the sound is coming out of the trasfer case.

Today I put the truckon jack stands, I selected 4 HI and 4LOW and the U-joint are OK, but the sound is coming out of the transfer case, with the 4 tires on the air and the front straight it doesn´t do the sound, but when I turn the tires wathever left or right it does and if I accelerate it sound worse, what could it be now, what I need to check?????????

Yes, it is constant just on 4x4 an dit gets louder when I do a U turn, how I know what gear I´m running on front?

yes,the guy that sell me the truck told me that he had changed to 4.56 but I am not sure if he did it in front too. But about the CAD it seems to be working fine to me acording to the test that I did.

I just checked the CAD and it is OK, I aplied vacuum and doesn´t loose, I checked the diff fluid level and it´s OK, what else could be the problem? : :???: :help:

Nice truck! what did you need to do the wj brake booster and master cylinder swap? :thumbsup:

4.0l 6 cilinder :yes:

THANKS CW! There is no problem if I install the washers?, I drive it on both sand and road. I have the stock engine and transmission(automatic), the engine just with the 2001 intake maniful and no fan clutch. There is a problem running that gears?

THANKS! but no I was at some dunes when I realize the problem, and yes it sound like something sliping, what you mean with CAD, the vacuum actuated thing on the differential? Thanks again!!!!!!!! :help:

First sorry about my English :oops: I have a problem with my MJ, when I engage the 4x4 I can hear a strange sound coming from under the front of the car it only does in 4HI or 4LOW when the car is on movement and it gets louder when I do a U-turn the differential has a vacuum actuated diaphragm. It is suppose to have 4.56 gear in it.(front and rear) with 31´s Thanks! I hope you can understand me!!! :D
