I plan on fitting some 1937 Ford wide-five hubs to my 1928/29 Ford banjo rear axle. I already have the hubs (two-piece design) and wheels. I’ve done some research and understand that Ford made a switch to a different rear bearing in 36/37 (P/N 68-1225) which had a smaller diameter (O.D.) of 2.84” than those used from 1928 - 1936. I can’t really find any info on the rear bearing used from 1928 - 1936 other than an eBay ad listing a P/N B-1225-A with an O.D. of 3 3/16”. I’m trying to figure out what bearing I would require.
I have measured about 2.064” O.D. on my rear axle where I assume the bearing would sit. I measured the I.D. of the 37 two-piece hub where the bearing would sit at 2.807”. These measurements are not likely not 100% accurate, but should be close enough to the actual measurements. To complicate things perhaps a bit more, I found this old post mentioning a difference in the bearings used between the one and two-piece hubs.
So, the question is - is there a bearing that will work with a 28/29 axle and a 37 two-piece wide five hub?
