I beleive you should be able to reinstall the yoke without a new crush collar,.it should be already crushed to spec inless your pinion bearings are worn, it takes alot of torque to crush it further. so put some blue locktite on the threads and take the nut down tight. the pinion with a inch pound torque wrench should take 96-144 inch pounds to turn the pinion gear and it's bearings after your yoke nut is tightened for proper preload. I have seen crush collars take over 250 foot lbs to even start them to crush. so if you tighten up the nut with some locktite to around 75-100 foot lbs it will easily hold the yoke and should not crush the collar further then it already is thus not changing the pinion bearing preload anymore then it originally was. now if it was already out of spec on preload thats a whole nother process.
