I dont mind sticking with the ball bearing setup. I am not scared of the setup as they lasted many miles before I came along. I am just cringing at the price of them and it doesn't look like many options on price are available. However it is what it is and the cost of doing business as they say

The MBS bearings were about twice the price of the OE ball bearings. Considering they didn't fit well on my truck, and I went a different route. Kind of a hard pill to swallow. Hindsight is 20/20 they say.

It would be a relatively simple task for any competent machinist to adapt the hub for a commonly available tapered roller bearing that has a cup with a slightly larger OD than the present bearing, and machine a sleeve to slip over the spindle to accept a compatible bearing cone. The sleeve could also be extended to provide a suitable seal surface at the same time. It would be a one-time modification that would solve the problem forever. Or is that approach too simple?

After reading this post I started searching around for bearings by dimension. I found one and ordered it to see how it would fit. I found it on ebay:
15590-15520 Tapered Roller Bearing Set Cone & Cup. These are the outer bearings. The race OD shows the same size as the original. The inner race is bigger than the spindle, but the original inner race actually fills that space pretty nicely like a sleeve. Aside from being a bit wide, it looks like it could almost be used as a sleeve as is.
Is it insane to put a sleeve between a bearing race and spindle? Should it be press fit in so you don't have it spinning?

So I've been searching for front bearings, found them on rock auto at a pretty good price. For my 1956 dually part numbers were the seal 40973s, the inner bearing is wbb46, and the outer is a national b45. I paid i believe about 180 Canadian plus shipping. much better then the local bearing shops that wanted 243 Canadian just for the outer. thanks for all your help, next is the clutch.
