I pulled a 31 spline 9 inch out of the junkyard out of an 81 F100 2wd. When I got it home I realized the lug pattern was 5 x 4.5, something I didn't even know they did on full size trucks. Does anyone know if I go get 31 spline 5 x 5.5 axles will they slide right in?
I *think* they used different bearings and/or flanges, I would get another one its not like they are hard to find or anything. I ran into the same problem a few months back and just got another one. Kept the old housing to build it for links and airshocks. or just as a spare.
5 on 4.5 is passenger car lug pattern, Sounds like someone swapped the rear in the truck
