Break in Front Prop Shaft - The 1947 - Present Chevrolet & GMC Truck Message Board Network

'71 GMC JIMMY K/1500. 350, SM465, NP2O5...
I had this annoying tick-tick when decelerating.
I thought it was just a bad U-Joint. I got under and pulled out the bad U-Joint, but then noticed some breakage on the rear of the Front Prop Shaft inside the double-jointed CV unit.
Not sure how to fix it. Don't even know what it's called...
EDIT-- Double Cardan.
I dropped the prop shaft, but the 4 bolts that hold on to the rear U-joint are a hassle to extract. I will have to get the double-jointed part off so I can run in 4 x 2 mode until I get my Prop Shaft fixed or replaced.
