I have a 01 Durango with a 233 transfer case. It's making a clicking/popping noise. I think I found where it's coming from but seeing as how I know next to nothing about 4 WD I need some help. It seems to be where the front driveline bolts up to some sort of a coupler (I said I'm pretty dumb when it comes to 4 WD) I've attached pics of it to help explain. What I'm wondering is if it's replaceable. The front part looks like it bolts on. Any help would be welcomed.

 

I cannot add another pic for some reason.

 

CV joint maybe?

 

That was it! Unbeknownst to me there's a CV joint on the front drive shaft at the transfer case. I ordered one from rock auto for $89.79. Parts house wanted $154.00 for the same Dorman part number.

 

Some trucks had cvs and some just had u joints.
