I get a Bad Grinding sound When i Engage 4WD

I was wondering if anyone had any ideas what could be causing this noise.

I have the 2WD, 4x4 part time trani. with the 231 t-case. dana 30 front end.

The sound starts most the time after i turn the wheel to the left or right while moving. And this only happends while it is in 4WD. Almost sounds like metal grinding?

Any info would help, or any info on how i could find the problem myself.

Thanks.

1. wrong place for this type of question, but thats ok it's your first post..

2. No sure exactly what you're trying to say but when you change from 2wd to 4wd the jeep should be moving very slowly (like less than 2mph). I think thats what youre supposed to do. It said that on an infoCD that came with my dads TJ.

3. Grinding is bad, it would be good to get that checked out by a pro or use the search option on JF.

4. You own a cherokee, the following link will be your social life from now on, Cherokee Technical Forum

Are you driving in 4wd on the street or on a dirt road? You should not drive in 4wd on the street - it will cause binding and weird noises.

No i always use 2WD on the road. but When i heard this noise I was testing my 4WD out in my drive way.
So if it doesn't grind while I'm on a dirt road I'm good?

No no, grinding is bad. try and describe this grinding a little better....does it sound like it is coming from underneath you? or from the front axle? is it def a grinding? not a clicking or anything like that? can you feel it in the 4wd lever? etc etc. try and say it as best you can. diagnosing stuff is hard over the internet so the more info the better

Okay I understand that.
It's defiantly a grinding noise.
I can feel it in the steering. haven't tried holding the 4WD lever.
If i turn the wheel all the way over it really grinds and feels weird in the steering.
This isn't a clicking problem i am talking about. although i have noticed sometimes when i turn the wheel from the left to the right i get a click sound down by my feet. (only clicks once) but i think that is a different problem. I'm just worried about the grinding right now.
I will check it out again tomorrow and try and pinpoint where the grinding is defiantly coming from.

ok let me think here......have you checked your wheel bearings at all? to do this just jack up the front end and grab the tire tight on the top and bottom and try and wiggle it in and out. it could be your power steering box as well but you only said it did it in 4wd so im leaning away from that. have you checked your front axle u joints? you can check those easily while it is jacked up too. just spin the tire back and forth and see if there is any play in the u joint.

if the click sound is more of a clunk, it might be your tracbar mount. those sometimes get worn and start moving around when you turn, this happens even when the bolts are tight.

I know this doesn't help much right now but at least you know what it might be.

Is your driveway dirt or asphault? If it does it on the road this is normal. If it does it on dirt, this is bad.

Edit: if on dirt, it could easily be a u-joint.

Does your engage light go on as it grinds or does it engage, and then grind at a certain RPM?

yes i did that to check the wheel bearings right after i bought it, that was just a few months ago. I thought the u joint was okay. but i'll check again.
