I have a 78 fulltime 4wheel drive Bronco and the rt rear shaft is bent. Is there anyway to know the spline count without taking it apart? This is my daliy driver, so I can't really afford much if any down time. I do know it's a 9" rear end and that's about it any help or suggestions will be appreciated.

Unles you have upgraded your axles you will have 31 spline from the factory. being a 78 it will also be a larg berring 9" i hope i have been of assistance to you.

ogre, i thank you much, that saved me a saturday that i can now replace the power steering pump. again much thanx
