Is this axle stock? (1 Viewer)

Rebuilding axle I pulled off parts 79fj40 truck just curious if this is stock or if grinding was to make birf fit?

It looks like mine (stock). What grinding? Are you refering to the machining behind the races?

To me it looks like an aftermarket birfield and the housing was ground to fit it, but I am by no means an expert

Either way it works. I already had a few beers and ended up putting to much thought into how its made etc.

It does look like someone did some grinding in there. Is there any chance that the axle housing isn't actually a 1979? A 79 "should" have already had larger knuckles to accommodate the larger later birfs.

Looks like the grinding wheel touched the back of housing a little. I agree why would you change the housing on a 79? PO's can't out think them

I have the same looking birf (exact) in my 82, again it looks stock to me.
my axel housing only has the inner machining around the races and seal tho. No other kinds of grinding marks. Perhaps a previous broken birf caused some one to "clean up" the inside prior to reassembly.

I'm almost 100% my axel is vergin as all items removed during rebuild had teq stamped or printed somewhere or another. Again, I have the exact birfield as you (same writings/nomenclature)

Dont know about axle housing but knuckle is right. So far everything I've snagged from parts rig looked untouched or at least stock.

I just pulled apart the axle on my 72. It looked identical. And I know it had stock components no grinding.
