How hard is it to change the carrier bearing in the center of the two piece driveshaft? I have an 02 CCSB 4x4 with the two piece driveshaft. Today when I was out I could hear a clunking noise when driving slow. I crawled under the truck and the bearing looks to be shot. The rubber that it is mounted in is all torn up and it is sitting in the bottom of the carrier. The shaft has a good two inches of play in it. Is this a job the average guy can do in the garage or should I take it in.
