Hello,
I'm new to the forum, I've got a 1947 3/4 ton. I am debating what to do with the front suspension, I am on a tight budget so I want to keep it stock, if stock is worth keeping. The front wheel bearings are about 1/3 the cost of an axle or clip swap, so if I get this figured out, i'll stick with the original axle. Here's what I've come up with: The original factory documents: (http://chevy.oldcarmanualproject.com/chevyresto/4877.htm

List the part number as 909026 and 909025.

The Timken interchange book lists B25 and B26 as compatible. See Page 214, http://www.timken.com/en-us/products/Documents/BearingInterchangeGuide7536.pdf

Lastly, by accessing http://www.showmetheparts.com/timken/#
and choosing "part search", entering B25 yields a buyers guide that indicates it fits "Chevrolet Truck 52-46." In the 'attributes' section it lists the sizes which off all the dimensions that seem to match the factory guide.

Based on all this, I believe the 3/4 ton wheel bearing part numbers are B25 and B26. As for the seals, I don't know where to get started.
