14bff crush sleeve won't crush

I'm surprised so many people have trouble with this, I did mine with my 1/2" drive Ingersoll Rand impact.
In fact, the *only* diff (out of the ~25 I've done) that my IR impact couldn't loosen/tighten (or set preload on) was a 1.75" D80 pinion nut (14 bolt nuts are 1.5").

Hmm, I believe you, but I also believe my broken press. We spent a good amount of time with the impact wrench just getting it from 5lbs to 33lbs, I can't imagine how long it would take without pre-crushing it first. Maybe the steel is softer out there?

Its gotta be the altitude
But I'm not lying, I've setup a bunch of diffs (a couple 14 bolts included) and I've never had to put a crush sleeve in a press.
I've heard about the reputation of 14 bolt crush sleeves, 20 tons seems like a ridiculous amount to get the sleeve to start crushing
Not to say you guys are doing it wrong, maybe the crush sleeves I dealt with were thinner or easier to crush somehow. But I really doubt that my impact is capable of producing anywhere near that much pressure on a pinion/nut (or crush sleeve).
I have done a bunch of 14 bolts and I am about half and half, with half being fairly easy to crush and the rest requiring the press. Even had a buddy bring over his big bad IR 3/4" impact nothing doing, at least on that one.
I would like to see a solid spacer for a 14b too although I wouldn't buy one till I regear

When I rebuilt my 14FF it took about a 5' cheater bar and two people. The truck was up on a hoist so I was able to put my entire body weight (200+ lbs.) and using my legs and it wouldn't budge, finally had another guy come over and help.
I used the vice and big 'o cheater method and it worked OK on mine, but now the pinion seal leaks. Either I tweaked the pinion support, or my terrible u-joint angles killed it.
