Re: repairing rear axle housing bearing races..
I have used the Mac's journal repair sleeves you asked about. They worked ok. Not a simple job to install. The sleeves were a mile out of round and required some careful study to select a proper diameter to machine housings for the desired press fit. I am also of the opinion the wall is excessively thick which removes more material from the housing than I was happy with. I checked for straight, rough turned with carbide, finished with grinding wheel. If I do any in the future I will make the sleeves, as recommended above, rather than purchase those with the extra-thick wall. I will also do them in one operation in the crankshaft grinding machine rather than a lathe.
