I can't slide my axles into the new bearings. My axles were in rough condition, so I sourced used replacements. The new bearings and seals I ordered came first so with the third member out I flushed and lubed the housing then installed the new bearings and seals and installed the cleaned and serviced third member minus the spider gears as I’m going to put in a Lock Right locker. The old bearings that came out are the same number as the new bearings. “Koyo RNU-0727” As I Insert the replacement axles, that appear to be in very good shape, they stop when the bearing surface area of the axle meets the bearing itself. I’ve got everything well-greased up and did plenty of wiggling, rotating and medium tapping with a dead blow hammer. They start to go in just a bit but just stop. I’m afraid to pound on them anymore as it took a bit of whacking to get them back out the little bit I got in. I’m able to install the outer part of the Lock Right into the side bearing and onto the axle splined end so I know the axle is centered and aligned. The Lock Right flange slides in and out freely so it’s not keeping the axle from going in. Besides these replacement axles I have the old pair that were a bit pitted and another pair I pulled from a spare axel that were also pitted. I wired wheeled and cleaned very well the two pair of pitted axles and tried to install them also with the same results. The old bearings BTW drop right onto all six axles. Is it possible I got some bad bearings or am I doing something wrong? I thought possibly the used axles could be mushroomed out to the unused surface, but I can’t detect that with a digital caliper. Any ideas?
