H9 Axle Question.

If I have the H9 axle code, LS 3.55, rear, do I also have a LS front diff?

Not very likely. Jack up the front wheels, lock the hubs, and see if you can turn the wheels in opposite directions...

If you had a limited slip in front, the axle code would be three digits, not two, i.e. axle code H92. Two digit code means you have an open diff up front.

If you had a lsd front diff the axle code would be 3 digits. There was a guy on here in the last few months that had a 92-96 f150 with a lsd in the front from the factory.

So my next question is Are the parts interchangeable between a Dana 44 and a Dana 44 TTB?

Yes, a lsd or even a lunch box locker for a solid Dana 44 will work. There are different spline count variations with the Dana 44 carriers. Your TTB is 30 spline.

Alright, That'll be an up grade we do sometime this year. I was thinking ARB's on both ends but If I already have a LS in the rear might just get one for the front and call it good.
