The crappy torsion bar 1/2 ton Fords have 8.8 front ends. The original poster said his truck is 2wd. That is a d-44 REAR end that he is talking about. There is very little difference in strength between a Ranger 8.8 and a d-44 rear end. Only the 31 spline 8.8 would be stronger.
If that d-44 has the two piece axles in the rear(little sheet metal cap in the middle of the wheel flange) stay away from it!!!! If it where something you absolutely had to have, you can get better axles.
Ford 9" from an E.B. would be a better way to get 5X5.5 bolt pattern. They come 28 spline as well but, 31 and 35 spline axles are readily available and reasonably priced.
