Stretched chain = noise?
 
My jeep has a loud noise coming from somewhere underneath and I'd like to know what it could be. I was just wondering if a stretched transfer case would make more noise than usual. I've got the 231 and I know the jeeps been driven on the streets in 4wd so the chain is probably stretched. Could the chain be my noise?

Get under there
 
Have you climbed underneath? It's probably the exhaust. Go under and look at sway bar links, shake the pipes, stuff like that. Since you say TC, does it only happen when the truck is in 4x4? Could be something simple like UVs up front that are worn out. Shake the front shaft and see if there is play in the UV/CV. And what kind of noise is it, clicking, churping, grinding.

Yeah you need to get under there and look around. Or you need to be a little more descriptive with where the noise is coming from. SOmewhere underneath is kinda vague... when does the noise occur? All the time? Under acceleration? Braking? 4x4?

Sure a strecthed chain can make noise, but so can a loose bar pin.

check fluid in Transfer case, chain will be noisy if low on fluid

The noise is just everywhere behind the front seats, and a little louder on the drivers side. Its a grinding noise that I am certain is coming from something mechanical.

Hi Thumper,

I have a 88' grand wagoneer that is giving me the same simtomes as you.

I am getting some sort of crazy noise from the transfer case, not a grinding noise, but more like a bad bearing noise.

I get the noise in all conditions, 2 and 4 wheel drive.

I have a little bit of slop in the front and rear drive shatf going into the tranfer case.

Anyway, I jacked my rear end off the ground and let the car idle in drive to pin point the transfer case.

Can someone give some advice as to how to check the tranfer case fluid? Also, can someone tell me what kind of fluid I need to add to the the tranfer case if it is low..


thanks,
AB

What transfer case do those Grand Waggys have? If its the same as in our Cherokees you just open up the fill hole (top hole) put your finger in and you should touch fluid. The transfer case is full when the fluid is up to the fill hole. Correct fluid is ATF.

thanks
 
Eric,
Thanks for the quick response.

I am not sure what kind of tranfer case I have. I supose I will find out today when I roll up my sleaves and climb under it.

So any dextron III ATF will do for the transfer case fluid?

Thanks a bunch.

Great forum!
