I have no idea what your cost savings were, but my net cost to replace the drive shaft with a rebuilt unit with new u-joint, new rubber mount and new bearing was $248.00 It took less than an hour to change. If it would have taken more than three hours longer to replace just the u-joint in my drive shaft, not even counting the cost of the u-joint or u-joint parts and the rubber mount and bearing (both of which my car needed and were included with the drive shaft along with new centering sleeves), then I would be better off working the three hours in my business and I would be be money ahead. Plus, I have a warranted, balanced drive shaft. I know that everyone has different priorities and that each of us has to make relative sense of what decisions we make, so no one answer is right for everyone. This was, in my opinion, the best choice for me and I'm very happy with it. After all the maintenance was finished, my car ran smoother than at any time in the last ten years.
