Not useing the Truck as a sports car I am hauling scap metal through mountain roads. I was not just going to put the rear brakes on without upgrading the front. You are mistaken about the weak brakes on that era of truck, they do have small 11.5 inch front rotors compared to the 13.89 inch front and rear rotors on later pickups. Dodge would not have made such a radical change if there was not a problem. My biggest problem is brake fade due to the small diameter rotors. I pull loads over steep mountain roads and need better brakes. My orginal question, which people seem to be ignoring for some reason is can I use 2005 steering knuckles on a 1998. I want to upgrade the front brakes to larger rotor like the 13.89 inch rotors on later trucks.
