I tried searching and couldn't find anything on this

is there a easy way to tell if I have 27 or 30 spline front axles? or do I have to take it apart to check?

I have a 03 sport with a dana 30 front and 3.73 gears

there is no tag left on the diff for me to decode

ALL Dana 30 front axles come stock with a 27 spline inner shaft. to change to a 30 spline there are only a few Lockers ONLY that are avail to accept the 30 spline fitment in to the D30.

If its stock its 27
If its not stock and its not got a locker its 27.

Thanks for the reply. I was figuring I had the 27 but wasn't sure.
