Front Driveshaft U-joint replacement

I had a vibration starting on the truck that was noticeable by about 70 MPH. I have already crawled under once before to attempt greasing the joints and check for play, but the u-joints seemed good. This is why I always suggest a full removal of the shaft so it's not loaded by hanging / gear tension. Now it's been some time since I've really been a mechanic, due to my cancer (strength), but I need to keep up with my repairs on Beast. @Tweety Bird came out to document while I was working. Strangely enough @Doubletrouble called while I was working and helped him set up a Quadzilla on his truck at the same time.

I was smart and bought a full rebuild kit for the front driveshaft. 3 u-joint and the center bearing for the double cardan joint. When I got the front joint removed from the front axle, the one bearing cup fell off. Yup, I found the bad joint in the front u-joint, but I continued to remove the entire shaft to check the full range of motion to see any other damage to the u-joints. The double cardan joint was fine. I broke out the grease gun and pumped a good load of marine grease into the double cardan joints. Replacing the front u-joint was a snap with a pair of needle nose pliers, pluck the snap rings out, and using an old socket tap out the one bearing cup and tapped it back the other direction. Popped the other cup out. Quick clean out of the front yoke and slipped in the new u-joint, but remember to place your grease zerk in the proper location so you can reach it later! Now finish up and install the driveshaft again.

@Tweety Bird went with me for the ride. The truck is so smooth, even with a quick blast to 90 MPH, it's like glass again. Smooth, no vibrations, and very enjoyable to drive. I'm so happy the double cardan doesn't require rebuilding.
