Hy bigcopter, yes the inner race is removable, it may include the seal surface area. As far as standing up, obviously the screw in cap axle is a 1 1/2 ton axle, so it is lighter duty than your bolt on cap axle which is a 2 ton axle. The bearings will not interchange. The 1 1/2 ton axle made it this far with ball bearings, and as long as you don't severly overload it it should hold up just fine. It sounds like you have the original "barrel bearings" by New Departure, you should be aware that these bearings haven't been manufactured for decades, there may be tapered replacements available for your application, but don't mix and match bearing types. Don't be too nervous about using the 1 1/2 ton axle while you overhaul your 2 ton axle.
