Go with the larger radius Unless anyone can find it in any service manual for any vehicle, DO NOT USE ANY LOCKTITE on ANY wheel bearing races or bearing surfaces. Because: There is heat transfer between the hub and the press-fit outer race. It's press-fit for several reasons It's not supposed to spin There is better heat transfer with metal-to-metal than any fluid between surfaces. You should not oil or lubricate the outer race before pressing (driving) it into the hub. The oil acts as a heat barrier. The bearing's inner race that slips over the spindle should spin - it is an additional bearing surface. Mack, Ford, Caterpillar,... etc. would not waste money precision grinding tens-of-thousands of spindles if it were better/cheaper/easier to press-fit the bearing onto the spindle. If the spindle is excessively worn ON THE BOTTOM (0.005 - 0.010"), that mean that the spindle is worn and should be repaired or replaced. Punching and chiseling dimples is not a repair... it's a hack-job when you're a thousand miles from nowhere. Locktite thread-lock and/or retaining compounds are not intended to fill gaps greater than 0.15mm... 0.006 inches.

I was amazed at how easy my B steered when barely moving - as fast as the starter would turn the engine. The engine was blown so I jockeyed the truck around with the starter. It might be easier to adapt an electrically assisted steering column?😁

Version 2. I like vertical better.
