New user here. have a 97 F350 crew cab diesel 4x4. workn on front end and havind issues getting a replacement dust seal for the front end dana 60. The seal goes at end of dif tube on the inside boss of the inner drive axle. I keep getting the same part number for the outer seal on the outer drive axle on the hub side. 710413. Problem is the inside diameter is to big. I need one w 2 1/8 id. The outside one is 2 3/8. Same seal just different id. Anyone ever have this problem? Dealer cant even find the right part number.
