binding and crunching T CASE?

[woodwardsh3]

So I went to the doctors to day in the H3 park an go in and come out put it in drive, and I hear some binding. It was totally quite on the ride there. So I Put my foot on the brake and gave it a little gas, and it sounds like its coming from the t case. So now I start driving home when you give it gas it makes noise at 45 it's quite. put in neutral at 30mph no noise costing rev the motor no noise.Put it back in gear and the noise is back. Sounds like a very bad wheel bearing but it's coming from under the H3. I noticed when going from forward to reverse the front drive shaft at the T case rotates more then it should and clunks. I have new u joints front and back. The back of the T case on the driver side was quite hot the front half was not very hot.
My H3 has 138000 miles I bought it used and I changed all fluids at 115000 miles. And all fluids did not look that bad. Im thinking the chain slider came off and that is the noise it does sound like the chain is rubbing across metal when its not grinding an popping. Is there someone close to me that has repaired one of these t cases. I have a hoist in my garage and tools I can get it removed. But is there anybody that has done this and would like to help me crack it open an rebuild it. I will have it out of the H3 and I can put it back in. I just need help with the rebuild. I had my 2ed back surgery in late march 2017. Im not working and we could do it here or at your place. I have plenty of tools. And im not in a big hurry. Time wise probably in july
Forgive the rambling im on a bit of meds to day and don't always think clearly.
I live in Lake orion Or I can bring the T case to you.
I do 90% of all my car repairs ive never done a T-case before.
I will do more diagnoses to be sure that the T case is the problem.
Oh one more thing there is no codes on the dash and I drove it in 4 high {not in locked 4 high}

Pull front drive shaft and see if the front output shaft on the transfer case is solid, I replaced my transfer case because those bearings were caused chain slip.

I will do that in the morning and drain the oil. thanks

If you've done a lot of car work you should be able to remove and work on the transfer case. Don't keep driving it - mine was binding and was repairable, until I drove it and the insides came out through the case like Alien.

I took off the front drive shaft and the front differential is tight and quite. I think the CV joint is the culprit the grease has leaked out. When I drive it in high lock with out the front drive shaft the binding is gone. And when I shift to low lock and back to high no grinding. So im going to take off the cv and replace it. I will order a rebuild kit and try it in a few months when my back has healed up better.

Yup. Very common...the boot rips...the grease flings out from centrifugal force...and the balls go dry.

You can replace just the CV...replace the entire shaft with a new stock one...or convert to a custom built traditional cardan-jointed shaft.

I sure jumped the gun on the sound it was awful. I didn't think it would be the cv as I replaced that one about 1 1/2 and roughfuly 25000 miles ago with the cardone model.

This may sound like a stupid comment. But you did put greese in ight last time?

Someone on this board makes an adapter to replace that. But you have to replace the drive shaft too.

Yes It came with a bag of grease. The rubber came unseated about 1/4 the way around. When I grabbed the prop shaft I got a hand full of grease.
Thanks
