Did you get a new crush sleeve? The crush sleeve holds a preload on the bearings by collapsing a pre-bent shoulder on the sleeve. So anytime you relieve that preload your supposed to replace that sleeve, that's why you have to re-torque the pinion nut to such a high value. Now with that said, if you re-install the old sleeve like many guys do, you'll tighten that nut until there is no end play in the pinion shaft and give it another half of a hex or 1/12th of a turn. Make sure you use red Loctite on the nut. (I suggest making a holding plate for the yoke and use a cheater pipe to hold it. Use a cheater pipe on a good 1/2" or better yet 3/4" break-over bar to crush the new sleeve to zero endplay and your good.)
