I'm starting a ring and pinion replacement on my Ford 9" diff. I'm going from a 3.70 to a more street friendly 3.25 ration. In pulling my axles to drop the pumpkin I found the driver's side axle shaft's splines had begun to twist. I can't imagine why that happened
I'm running a Currie 28 spline crate rear end with a TSD posi-carrier.
My options as I see it are:
1. Let her ride and hope for the best (no more twist and ultimate axle failure)
2. See if Currie has a stronger set of 28 spline axles and replace them. I don't
think they do though.
3. Replace axles and posi unit with a 31 spline setup.
4. Replace axles and posi unit with a 35 spline setup.
What does everyone think?
