I replaced a leaky front pinion seal. I went to the dealer and picked up new seal and crush sleeve. My question is...How tight do I tighten the pinion nut with a New crush sleeve?

Since you removed the nut before taking measurements, torque it until it reads 15NM or 2 inch pounds rotational resistance with wheels removed

I've seen where some people have gone as high as 600 ft lbs?? And looks like I need an inch lb torque wrench. I went to 200-210 and still sloppy.
Torqued my Dana 30 to 180 and put loctite, so far so good after 5000 miles
I Read 3-400 with new crush sleeve but i don't know how accurate that is
Yes it takes some torque. Buuuuttttt, it is the rotational resistance that counts, not the torque on the nut

So tighten in increments until I can get that reading with an inch lb torque wrench. And front wheels removed.
Yes, that will give you the preload you need on the wheels

Thank you Steve, now it rolls without the noise in 4wd. I thought I was to tighten pinion nut to 200 ft lbs. But with new crush sleeve and seal it needs to be much higher to get the sleeve to crush properly.
Glad it worked out

So how hot should that front differential get?
Just a concern.. I worry too much.
Diffs get pretty warm. 200 degrees is not uncommon, as with a tcase too
