Loved you line in your signature line about Angular contact bearings, just ask anyone from the old days as GM used them on the front wheels for years and a real PITA to regrease and set up getting the correct end play with the spacer and castle nut torque.
But what goes around comes around as all modern open wheel race cars use angular contact single element ball bearings in all the hubs front and rear with special grease. It is because they are a lot less friction than taper roller bearings and run cooler also. Set up is critical too, and the proper grease.
