2001 24 valve 5.9 3500 flatbed 4wd. Discovered the front right u-joint is sloppy to took it to a shop for repair. They never did get the hub removed. After they banged on it a while, I told them to sew it up. It drives ok, but I know it is just a short time before the joint breaks. Any practical suggestions as to how you guys remove these hubs?
