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.
