RE: Drive shaft carrier bearing
I have never replaced a center carrier bearing on a Dodge, but I did replace one on a 1985 Ford F150 about ten years ago. As I recall, the part was not that expensive, maybe $30. It took a hell of a lot of force to press the old one off the shaft. I was active duty Air Force at the time, and I did the work at a base hobby shop. They had a hand-operated hydraulic press, maybe 10-ton. It took about 30 minutes ofspraying it withWD-40, applying max force with the press, and tapping it with a hammer before it released with a loud bang! The new one went on without any trouble. If you replace the carrier bearing it's also a good time to replace the u-joints, since you have to remove the shafts anyway.
Speaking of driveshafts and such, both the shafts on my 2007 have a section of the shaft covered with a rubber boot, which I have never seen before. Does the boot cover some sort of vibration dampener? Does anybody know what those are?
