I'll have to give that a shot. But I believe yes.

 

I think I might of found my issue. I am hoping it's my front driveshaft. And not my t case. But, I took off my front driveshaft not completely. Just disconnected it from the front diff and unbolted the bolts where the yoke and universal joint sits. And I didn't drive fast because I didn't want to mess up the needle bearings. But It felt like the sound went away. Again didn't drive fast not even into second gear. And I just drove around the corner. But I didn't hear the thumping. So maybe.... I don't know. But it's a start wouldn't you say? Man I hope it's not my t case. I mean it goes into 4x4 4LO/N/2HI/4HI so...

I plan to buy a new front Driveshaft. Anyone know cheap good durable auto shops online?

 

I had mine rebuilt at a local shop. The joints in the CV end were dry and stiff, and made all sorts of rude noises in 4x4.

 

Just remove it completely and drive around normal. You'll know for sure then.
