Default 39 banjo rear hub pitting?????

Hello fellas I'm at my wits end, what would you suggest besides finding another rearend, I've looked at dozens and this has been the best one I've seen in years (pretty sad but that's Canada). I've read about Rear Axle Repair Sleeves, but I'm not sure if anyone around me could do it, also read it may or may not be safe? Ie failure?

I've repaired them with new sleeves and they have worked very well. I had a very qualified machine shop turn them down and I installed the sleeve per the manufacturer instructions. I'm still running them and would do it again.

Its not a complicated job, but you need a lathe with a big enough swing to clear the spring hanger.

Becareful who you get the sleave from. The best ones i have found are from the Columbia rear guy that i think is in Tennessee. They require the least amount of material to removed for installation

Third Generation Automotive (Michael Driskell) has those repair sleeves for sale on ebay at a good price. You could probably call him directly and place an order rather than going thru ebay.

I had seen a video of cutting the bearing surface down on a brake lathe with the banjo end of the axle tube hanging away from the lathe. Has anybody here done that?

I did the job on my lathe. It would not quite swing so I heated and bent the spring hanger and heated and bent it back again afterwards. One way around the lathe size conundrum.
I took a video at the time (poor quality, took on my phone).

I have a question should the area be ground ? Is the surface area hard and would the repair sleeve be hard ?

Original surface is pretty tough but carbide does a nice job turning it.
Speed plays a big factor in both rotation and feed so does the angle of the tool bit to the surface.

The repair sleaves are very hard atleast the ones i have used. Im sure someone can tell the exact rockwell rating

1. no, just be cut on the lathe.
2. the surface area we found was both hard and soft as the hardening varied in depth on the hub as we cut it.
3. the repair sleeve must be hardened, only get ones you know are USA made.

When we did mine the sleeves we had were very think so we trimmed them down to save more integrity of the hub .
