84 New purchase. Issues showed up driving home

Now I have two. 94 for me and this 84 I just bought for my 15 yo.

Driving this thing home it started with a high pitch squeek hwy speeds. Thought it was a.wp cause there was play in the shaft. Then thought maybe a alt. No one had one while traveling 3k miles. Then a vibration began showing up on decel. Got worse and worse the last 1000 miles. Vibration comes and goes. If in throwing in N does nothing. I am now thinking t case or frozen joint in cardigan joint.

Am i in the right direction or am i.missing something?

The centering ball and its driveline pinion that holds it in place is what wears as well as both U joints in the dual cardan
Last one I had to replace the shaft end. It cost me 350 for a rebuilt shaft and the rebalance
I used Slyco
That is pretty damn clean for an 84, good job
