    Ford 9" ?'s

    I pulled a full width 9" out of an F-100 to replace the EB 9" I have now. Well I started tearing it down and and found that it also had, necked down, 28 spline. I was wonderiong if I could still go big bearing 35 spline with this axle? This axle tube has a lot bigger diamiter than the EB axle tube, where the bearing sets. It also has the same shaft diamiter as a 31 spline at the bearing, then it necks down twice to 28 spline.

    Do we have any 9" experts out there???

    yes you can still go big bearing 35 with an aftermarket third. If your looking for 31 spline look for a later f150 or bronco.

    My plan was to go 35 spline anyway.
