It was thought that when the hub assembly with the press fit removed,
the clamping force of the yoke nut would hold the assembly and prevent the
inner races turning on the shaft.
Okay - Now - not in reference to UltraVans, but to the cars. This may have
started because almost all Chevy Dealer mechanics who had to rebuild the hubs
on the (late) Corvairs and Corvettes built a special tool for the task. The
design of the Vair/Vette means you have to press the assembly together to
figure out the exact shim needed between the inner races if you replace either
bearing.(In order for the assembly to fit the machined bearing carrier housing)
Either you are really good, or you press it together and apart a few times to
measure the play after assembly, then adjust the shim thickness to
compensate. The dealer mechanics would turn down (very slightly) a Stub Axle to allow
the bearings and shims to be slid on and measured, then slid apart. Only when
the shim pack and the bearings matched the requirement of the housing would
you use the original stub axle and press the assembly together. This was a
real time saver for the dealer mechanics - and for anybody else who rebuilds a
lot of these. Like Jim Davis, I think the press fit is best. Yes, the
slip-fit might work well for thousands of miles, but, at least for the 65-69
Corvair, it is not the way it was designed.
