defective thermostat put it in a pot of water with a thermometer and see what temp it open and if it is opening all the way

another note do not use this program on 64 bit windows, you may get lucky but i had a problem with the canny 7 staying connected works fine on 32 bit windows

thanks for all your help glad to hear your on the way of recovery i also got a defective power board and am waiting for another. to bad about the cab mounts but that is another story

i think you should pull the fuse on that until you get to the dealership

thanks Kyle guess i can scratch that fix off of my list lol

thanks flipz71

thanks very much JP going to order it

part number 1 the drive hub has a compression ring on the end of it. it will come out but there is two bearing behind it, one is a needle roller type bearing that the shaft rides on and the other bearing carries the end of the carrier. you can replace the needle bearing and seal but if it is the larger bearing you have to split the housing in half to remove it. let me know if you find the part number for the needle bearing i also have to do this
