I have a 2001 screw with a 5.4L. do I have a 9.75 or 10.25 rear end? Whats my front axle? Did some google search but couldn't find anything definite on the rear or anything at all on the front. Also anybody know the splines on each?

9.75 in the rear and 8.8 in the front. The 7700 series have the 10.25

It's the 9.75 and what's wrong with it because I've ruined mine twice

Front 8.8 is a 28 spl and the 9.75 i think is 34 spl
