150,000 mile 95 cherokee sport 4.0

just had diff fluid changed in front and back and transfer case fluid changed.

was a bit rainy out tonight so i put it in 4 wheel drive, and theres this weird sound now. just kinda loud, sounding. not a terrible sound but weird to say the least.

this is my 3rd cherokee sport and ive never heard a peep outta the 4wheel drive before.


any ideas?

 

What kind of fluid did you put in the transfer case? May be a stupid question. But hoping Dex III/Merc

 

hoping the right stuff. this was something i had the garage do.

i was thinking too that maybe they put in the wrong fluid but i wouldnt think theyd be that stupid, yaknow?

 

yes, they would.

if you dont tell them what to put in things, they just stick whatever they think in it, in most palces.

unless its a good place you can trust youll get the shaft. You should really do your own work.

 

Well if you have a np231 tc and you put it in 4 wheel drive on bare roads( only rain) well that might have something to do with it.

 

Yeah you really do need to tell them exactly what to do. Replacing fluids are pretty simple jobs that you could have done yourself. I am not at all mechanically sound but have learned a lot through this forum and can now do any fluid myself. And you will be able to do the same if you take the time to search and read. It's worth it!

If I were in your current position, I'd do a search here or even get a Haynes manual (or something similar) and find out how to do this job yourself. It's really simple. And i'd replace the fluid again, even though you just got it done because it's a good possibility that you have the wrong stuff in there, hate to break it to you man.

 

x1213340923081 np231 4wd is for snow, mud, slush, loose dirt, etc... Not for a little bit of rain. Why were you using 4wd in rain anyway? Even if you have the 242 and had it in FT, ITS STILL RAIN!

Your chain could be loose, the fluid level could be low, they might of put gear oil in it (most tcases use gear oil, but I dont see this suddenly causing a noise), etc.

Im on my 3rd jeep, and my girlfriend has a 96, they all made a little noise in 4wd...

 

thanks for the info guys.

appearntly according to the invoice, they put in 2 qrts maxlife transfer case oil. and 4 grts total 75W-140 synthetic gear oil for the diffs.

i would have done this myself, but ive been really busy with work and things around the house that i just didnt have time. next time i will deff do this myself.

not excatly sure why i used it on bareroad in the rain, i guess i wanted to see if there was a difference in feel with the new fluid.

ive just never heard this sound before from any other cherokee i owned.

i did just get new tires for it too that are pretty heavy duty, maybe that has something to do with it?

 

Could very well be, especially when all 4 wheels were grabbing. But I agree with defiance; a little bit of rain is nothing for 4x4, and you may have insulted your XJ by suggesting she couldnt handle the rain in 4x2, hence why she made noises at you. Lol, jk. But in all honesty, dont use the np231 on dry roads or for a little rain. Your ol' girl will handle rain just fine. As for any noise, just remember that XJ's are very vocal, and noises are part of the package. If you didn't hear any noises, then I'd be concerned.

 

again, thank you guys.

i do feel a bit better about this.

 

i shift mine in 4wd all the time on bare roads just to shift in and then back out i only do it like once a month maby and not for more than like a couple of sec. and i dont ever hear a thing but the gears wine

 

Read the op before you say something dumb, he left it in 4 wheel drive by the way he's explaining it.Pay attention.

 

sorry bout that i just took it as he put it in and it made noise didnt realize he left it in

 

No biggy hope I didnt seem to harsh to you didnt mean it in a bad way.

 

its all good i dont get bent out of shape on these boards cuz u never know what sombody is going to say
