Need to replace the rear axle bearing races. Can the race be punched out and pressed in by a shade tree mechanic (me) or does the job require a machine shop?? and question No.2, working on this spare rear axle assy and the right axle has a washer/spacer that has been slid over the axle and against the gear end before installing through the differential. Maybe to take up space. Is this done?? Thanks

The axle housings need to be turned down and new sleeves pressed on. This requires a long length bed on the lathe. Buy your sleeves from a reliable supplier like C&G. Tom

Are you wanting to re-build the outside surface where the wheel bearing rides, or are you referring to the bearing races in the axle bells that the differential carrier rides on?

The bearing races that support the gears in the center have rough pitted areas and need replacing. thanks

The races should be replaced while you have the axle apart to sleeve the ends. Be sure you know which axle you have, as the races and bearings are different for 32-36 and 37-48. If the hub bearing races on your axle are badly galled, be sure to inspect the bearing rollers for pitting. If they are Ford script bearings, they are probably OK. If repros, who knows? Again, know which bearings you have. The early bearings are 3.12" OD. The later bearings used in mid '36 measure 2.78". The ID is the same for all, so the sleeves fit 28-48. Be sure the shop that machines your housings knows what they are doing, and the housings should be checked to be sure they are straight. Most axle damage is caused by failure to service the hub bearings, and allowing the oil level in the center section to get too low. Be sure to check the pinion bearings for any roughness. If really bad, finding a replacement axle is a better choice.

The inboard diff carrier races can be removed with a draw-hammer, but if they are pitted, then it is most likely that as Super states, the pinion bearings may be due for replacement as well.

That shim washer slid over the axel shaft was probably installed to take up ecsessive end play in the shaft. Whether thats an acceptable fix needs to be answered by someone other than myself.

I suspect that someone put the washer on the axle to take up slack when they assembled the spider gears and housing. Check to be sure that the axles are the correct ones. Many rear ends were cobbled from junk yard pieces. From your description, it would seem that your rear end may need a lot more than sleeves.
