Is not the flange what splines onto the outer axle splines? Not the spindle?
I set it at 16 ft lbs and ran my safety wire.I find it interesting that differnet years and different versions of the manual do occassionally list different torques (or none at all) for the same applications. I put together that long thread from a couple different versions of bith Toyota and non Toyota manuals and have seen that earlier or later editions do sometimes have some differences for the same span of model years.
I think I can use the 22.8 ft lbs for the manual lock outs? I got these Sears lock outs from bmoonhajjar here on mud almost a year ago. I had to drill the mounting holes out to 25/64”. It seems to function fine.
