I'm trying to understand the differences between the front hubs of 85-88 740s and 89-later 740/940s.
The early spindles have a narrow end, a wide end, and a ~2" long taper in-between. The Later spindles have a narrow end and a wide end with a shoulder in-between.
The hubs seem to be different. (different nut and shape of the hub around the nut)
Does anybody know if these hubs are interchangeable? (ignore the tone wheel)
Which spindle design is superior? Would have thought the taper was stronger, but maybe one is cast and one forged?
Last question - anybody tried replacing the bearings in the later style hubs? I did it without any problems in the early style hubs. (found the PN on the race and ordered Timken replacements)
Thanks for any thoughts!
