Medium Duty vs Heavy Duty Safety Track
How do you tell if you have a medium duty or heavy duty 4 pinion safety track carrier ? The service manual says that the medium duty carrier is gray iron and the Hd carrier is nodular iron but does not say how to tell the two apart.Is there a N cast in the nodular carrier like there is on the center section of the rear end or a part number that is cast in it that will tell me what I have ? Thanks.
