1971 ford 9" axle bearings - 28 spline

carguy47 · Nov 21, 2024

Hey guys. I looked for a prior thread for this topic and found this one.

So it looks like the identified bearing kit and seal are identified. I am used to playing with the Big Ford - new style housings with 31 spline.

So I want to make sure I have the correct bearing set and seal for the 28 spline housing in my Mach 1?

Thanks

Axle bearings for 28 and 31 spline are the same part number - RW207CCRA

28 spline axle seal is National 9569S for an 1 3/8" shaft.

31 spline axle seals in these cars ride on a unique sleeve that is pressed on after the bearing retainer. The purpose was to prevent assembly line workers from cutting the axle seal with the splines when inserting the axles. This seal is National 9363S for a 1 1/2" shaft diameter.

OK, that's what I thought. If I remember correctly, the large ford 31 axles take a set 30 .

Thank you
