diff help
I have a 00 F-150 xlt 2wd, 5.4l with the 9.75 ring gears with stock ratio of 3.55. my problem is that I have broken my cross pin and spider gears. I'm trying to get it fixed temp. till I can afford the 4.56 gears. my problem is I cant seem to find out how many splines are on my axles. I dont have the time or storage space to tear my truck apart to find out. the tag on the diff cover is s 919 f 3l55 975 oco 9. ne Idea. I keep hearing 34 or 31.
