0 Steel Nose Posted August 13, 2021 Share Posted August 13, 2021 8QJ422 is a casting number, the actual Mack part number is 9QJ2100P15 that should be for a 24.5 wheel Quote Link to comment https://www.bigmacktrucks.com/topic/65885-8qj422-cast-hub/#findComment-478329 Share on other sites More sharing options...
