After talking to my go to gut for custom built driveshafts I've learned a staked U-Joint is not a replaceable part. You replace the entire driveshaft.

So I installed the new Spline Protector, greased the Splines, and reinstalled the Driveshaft making sure it went back in exactly like it came out.

The Driveshaft is encased in Exhaust Heat Shields so you can only see it near the Differential. I drove the car user a load with the new Hanger Bearing and the vibration is almost non-existent so I will be shopping for a new Driveshaft while driving my car again.
