Thanks Jim , But Im looking for more specific info . I have a case here where Ford says the truck was built with a Dana Spicer 135 , but it actualy has a Spicer 110.The issue arose due to what was believed to be a failure of the limited slip diff. one wheel was on ice the other on dry macadam and the truck was helpless to move. I have researched the 110 limited slip (TRUETRAC) and found it not suited in a one wheel 0 traction condition , whereas the 135 limited slip is . Im curious as to why Ford thinks its a 135 ( that I would rather have ) and was it meant to have it .
