0 j hancock Posted September 10, 2016 Share Posted September 10, 2016 What is your front axle number? It will be stamped on the right side near the spindle and start with FA. Depending on which one you have it will be .0005-.0020, .0015-.0070 or .0025-.0045. Quote JimIt doesn't cost anything to pay attention.
