Recently had to replace steering box on this truck posted under Steering Gremlins, well that problem solved. About a week later now replacing the clutch, kept hearing "noise" on trip last Saturday and kept thinking the radio but when I started paying attention every time I shifted could here it and then the light went on, throw-out bearing. Have new everything coming from South Bend but have question about the hydraulics? They recommended going to local supplier and getting new unit versus factory. My question is, is there an upgraded factory unit, I can buy new factory for about ten more than local after market supplier? Is there a later model year a better option? Going to call South Bend back tomorrow but any input greatly appreciated. As far as I know nothing ever replaced in clutch area, since I am in there I will replace all of it, hate to just replace throw out and have to go back later for other problems, especially approaching 300,000. Thanks again all!
