One of my Dad’s first jobs was running a service station in partnership with his older brother. The owner was a “Ford man”. Dad said the reason he preferred Fords was Henry’s extensive use of roller bearings. He said a Ford would be in service 30% longer than other vehicles because of this. I know Chevy hung on to ball bearings on their truck spindles into late 60’s and the the ‘30 AA has taper rollers that will way out last ball bearings there.
Also note: one of Ford’s sales pitches in model A era was comparing prices of their competitors replacement parts with theirs.
