Swapping Front Axle

I have a 1995 Jeep Grand Cherokee with the 4.0L and All time 4 wheel drive on 31x10.5 mud terrains with a 3 in. suspension lift. I will admit now that I don't know much about jeeps so that's why I'm posting here.

I'm almost 100% positive I need to replace my front axle, whenever you drive it makes an awful grinding sound like metal on metal and when I turn it makes a clicking noise. So first I was wondering if I am correct on it needs the front axle rebuilt or replaced, or if it is the driveshaft or just if anyone has any ideas.

And if it is my axle, do I have to get a Dana 30 axle specific to the grand cherokee all time 4x4 or can I use any front axle?

Sorry if this is a stupid question, I'm still learning. Thanks ahead of time for any ideas.

Attached is a picture of it.

Get under there and inspect the rubber boots on each side of the axle near the tire. If there are tears in them you need to replace the axle shaft. Other than that I would put a pan under the diff and unbolt the cover to take a look to see if there are any metal chunks in there. It's easy and cheap enough to refill it.

Definitely check the axle shaft CV's (or u-joints) first. They are clearly visible at the ends of the axle and relatively cheap to fix.

And yes, some AWD ZJ's of that era came with u-joint front axle shafts.

So we ended up just pulling the front driveshaft because the pinion bearing(from what i was told, maybe wrong) blew as I was driving and every time I drive it sounded like someone was beating the bottom of my jeep with a hammer so we had to pull the front driveshaft in the parkig lot of my work so I could get home and all the noises went away, so I'm just gonna leave it like that I can afford a new front axle! Thank you guys!

Just an FYI, if your transfer case wasn't shot before, it is now and will have to be fixed or swapped. Also, your Jeep will roll in park with the front driveshaft out.

Yep transfer case is junk now if you drove it with no front driveshaft.

Reliability is relative

I figured as much, I wanted to switch transfer cases anyways so it works out. Just will have to do the Front axle and Transfer case at the same time now. But will anything other than the transfer case get messed up from doing tht and driving it? And the transfer case only makes a difference if I put a new axle and put te front driveshaft back on, correct? Sorry if I sound like an idiot, I'm still trying to learn!

Don't park on a hill and make sure to use the parking brake. You can't drive these things around without the front driveshaft.

So as predicted my transfer case finally died. But now here is my question, I want to get the command trac transfer case which I believe is the Np231 (please correct me if I'm wrong in any of this). I was wondering if that transfer case would bolt right up to my transmission or not.

its a easy swap, but do your research first (or pull your t-case) to insure the input shaft spline count and length are the same, if you do this, the swap is painless

there is a nice write up(sticky) on the swap, after about the third time reading through it, it all made sense and i know what to look for.

good luck girl!

You could also call up George at Transfer Case Unlimited. He built me a custom X-fer Case for my 94 V8 ZJ. He does great work and is a very knowledgeable and friendly gentleman.
