Ford 8 inch bearing sizes?
I just got the posi unit for my ford 8 inch and, when we tried to install the new bearings, found that the bearings we have are too small. So, just to check, we took the bearings from the old (open) carrier and tried to slide them on and they have a completely different ID than ones we need. So then we checked the pictures of the different units to make sure the guy didnt send us a 9 inch and its a different design, ours looks just like the 8 inch he's advertising. To sum it all up, were confused...do the posi units have different size bearings? or do we have the wrong unit?
