So I'm in the process of rebuilding the rear end of my 260Z (bushings, bearings, struts, etc) and now have everything removed including the differential (R180 as near as I can tell).

While I have the differential out of the car, I am considering replacing all of the diff bearings since it has never been done before on this car and I felt that while I had it out it would be a good thing to do.

Has anyone ever done this before and how challenging a task will this be? Are there special tools required to remove and install the new bearings? Am I asking for more trouble than it is worth?

Thanks in advance for any recommendations.

Mike.

Just look at them. If the bearings and races look clean, run them again. If they look scratched up or if the ball bearing at the pinion feels like there is sand in it, then replace the ones that need attention. If you just press the bearings off an put a new bearing on, you shouldn't have to mess with the shimming, so it should be relatively easy. Tools would be a bearing splitter and a press, and a large brass drift for the ball bearing and the races.

Jon,

Thanks for the response. I will be tearing this down in the next week or so and will have a look as you suggest.

I have the press and the brass drift already so I just need to pick up a bearing splitter / separator if they need to be replaced.

Mike W,

How is the diff project coming along? I too live in Austin and have the same situation with a diff I have in my garage.

texasz,

Just saw your response. I have the diff with half shafts still connected out of the car. Removed the first half shaft last night and going through an inspection now.

While I have it out of the car, I'm inclined to just replace the bearings. I still don't quite understand how to press out the old bearings. I have a splitter as well as a shop press so I think that I have all of the tools. Just need to get the removal process down.

Perhaps we can figure out a way to hook up in Austin and share some Z war stories. Might even be able to help each other if needed.

Let me know.

Mike.
