Need quick ball joint torque help

Just installed a set of ball joints on my wifes truck. They are tight and binding. I know some have said they can loosen up in a few mies. I was wondering how could torque and sequence matte? I hand tightened top one then tightened th bottom hen tightened the top. I get how, overtightenng can strip threads, but the way the joints are pressed in tightening thotom it will bottom in the joints shaft not tighten into the ball aspect of the joint? Any one deal with this? I did a. Toyota truck before and they were tight bu got normal in amo th of use? Thx give me some imput

Yea but, the "lock" of the Ball Joint isn't relying on the nuts tightness...

The tapered shaft locks into the axle by the action of the taper (as you know from having to use a pickle fork to brake those tapers on all the FE links). From there, the ball & socket of the pivot point of the joint (where the stiffness comes from when they're new) is beyond that nut & taper-lock of the shaft.

Loose or tight, once that nut has engaged the taper, has no effect on that "stiffness", it's all internal to the joint itself and needs to "wear-in" before it goes away.
