I had all three shafts in. New front weld yoke, front u joint, carrier bearing, straightened the main driveshaft, both rears got new boots and grease and the rear between the drives got a new joint and splined slipshaft (wtf?!?). Also bought all new strap kits, since they are supposed to be a one time use only kind of item.

This makes me want to replace all the other u joints as well. I normally carry a tiger tool and a spare Spicer u joint in the truck...I pulled mine because of a vibration as well.

Glad you got it fixed though...sounded pretty bad...

I would replace all of those u joints. I learned that years ago, one goes replace them all, as the others are soon to follow, like Rawze discovered. A few years ago, on this truck, I lost the carrier bearing at a dock. If it is going to blow, I cannot think of a better spot! Towed it to a shop and got looking underneath... Found one questionable u-joint, I said replace them all, and glad I did, I was driving on borrowed time. These babies looked good on the outside, took grease, etc., but when we removed them, I honestly count my blessings. I could not believe how bad the bearings were under the caps, these things were beyond toast and certainly would have failed in short order. I was honestly surprised that I still had my drive shafts still attached! The mechanic was like holy shi#t man! LOL!

I'm stupid anal about this stuff, if there are two or more of something, I replace them all when one fails (Of course within reason). Learned this working in an auto repair shop when I was in High School. Those were fun times. ;-)
