3 NU1010's in each hub. Their load rating is enough to carry a Sherman tank. I've done this conversion and the cheapest place I could find to buy the bearings was this crowd. They also have the seal you'll need.
BTW, I have no interest in this company.

From what I've read, Repro-bearings tend to die very soon as of late, as low as 500 mls.

It has taken a lot of years but a weakness in Henry's hardening process is showing up now. The process didn't harden very well at the axle nut end of the hub so the hardening wears through - I'm sure most have seen it.
The standard repair is to put a sleeve on the end of the trumpet and in the hub, then use the smaller V8 rollers. The problem with that repair has been discussed a number of times here and in another forum. The sleeves for the trumpet tend to be soft and the rollers of poor quality. I have heard of a number of ways of using other over the counter bearings with varying degrees of success. So far no problems with this conversion on my car.

Yeah, I am not sure where this is coming from. To begin with, Ford did not make the hubs, ...Kelsey Hayes did. I have both Ford's and K/H drawings on the A-1116 hub (11456 is K/H #). The print specifies the hub to be a forging from 'EE' steel with a 'BB' heat treatment. It calls for a 51-55 Rockwell. If the bearing alone was kept saturated in good quality grease, these would have gone a lifetime. Matter of fact, type 'EE' steel is a medium carbon steel and when forged, it likely would have given many miles of service without the heat treating process.

But on to the root problem. Most owners did a poor job of keeping the hub bearings lubricated which is why the hubs wear. I have a plug we machined that allows to check the wear of the hub. Many hubs are worn out-of-round and/or on a taper. Machining for a sleeve only wears thru the case hardening. That is why replacement hubs are manufactured to keep everything within factory tolerances.

What are "those babies"? The hubs or bearings or NU 1010 bearings?
I can't remember exactly what I paid for the NU 1010 bearings at this company but I'm a tight @$$ so it wasn't much.

Wasn't there a post just a few weeks ago about failed repro rear wheel bearings? Or was that only the transmission bearings and the wheel bearings are fine?

Hey, I call it "Thrifty"! My buddies use the "Cheap" word.

Thrifty sounds better. I'm no longer a tight @$$ but will my wife believe that?
