Driveline vibration

There are three U-joints. One where the shaft connects to the transmission, one near the carrier bearing where the drive shaft splits in two, and one where the shaft attaches to the rear diff. They aren't terribly hard to replace if you know what you're doing or have a friend that does. My friend Zech helped me do mine.

 

I did it by myself with hammer and under size socket.Remove snap ring and Pound it lightly, It will slide out.
It's little tricky when installing new u-joints. Needles bearing tend to not want to stay where they should.

I used aluminum block as support and no vise clap.
