hi marc - though I would ask you as your id comes up whereve I look - i have a 2001 International FE 3900 School bus conversion, 40' Roughly 183,000 mileson a DT466 with a Allison MD3060 - the bus veers to the right and its most troubling when on a straight road and I have to constantly veer it straight. Sometimes its takes a while to get the steering back straight - where should I post this sort of query - under mechanical? Thanks for your time marc. Andy
