Well, the story didn't end here. The carrier bearing popped out again. So I took it back to the mechanic that did the work and he said I needed to replace the driveline and yoke to the rear differential as it was frozen. The additional cost was $350 more. So now I've spent $800. I noticed the new driveline has grease zerks on it. My original one was maintenance/lube free. Does anybody have an opinion on whether I got a better driveline or an inferior one to the stock?
