Greg and Bill,
When I researched the info I posted yesterday above, using Loren's provided info about the truck being a 1952 1-1/2 Ton "VK" (4400) model, the below screenshot from the
1958 Chevrolet Master Parts & Accessories Catalog shows the numbers you all mentioned to apply to 1950 and earlier 1-1/2 Ton trucks which doesn't match up with the Loren's described truck.
The ones you mention are "ball" style bearings, while the 1951-53 specific bearings listed for the VK 1-1/2 Ton are "
barrel roller" style bearings.
Loren did indicate the existing cup on the truck matched the Hyatt "A11424" cross reference. Maybe Loren can tell us what number is actually on the existing cup? Or maybe provide a picture?
Just trying to provide accurate info to Loren and not cause any confusion.
