According to the factory manual (which I'm looking at right now) - it's 400 Nm/296 lb-ft for the spindle nut for the 2wd (which I said before). For the 4wd, it's called something different - axle-to-wheel hub nut and it's 27 Nm/20 lb-ft. Not sure where you got 13???
So the factory manual is wrong? I installed a lift kit and torqued the spindle nut to about the limit of my 1/2" drive torque wrench - 200 lb-ft. I've had no problems whatsoever.
Are you talking about a 2005 or a 2001? I can't vouch for the 2005, but a 2001 2wd has conventional cone and cup bearings, and yes, they are supposed to be torqued in 3 stages to 30 ft*lbs, then backed off two turns, then to 17-24 ft*lbs, then loosen the nut, then tighten to 13-17 in*lbs, followed by the installation of the retainer, cotter pin, and hub grease cap.
It's section 206-03 of the '00 and '01 manuals, steps 6-11.
Also, I believe they changed the spindle setup on the 2wd for '04. I haven't looked at one, so I can't say for sure. I'll have some reading to do on them in teh AM when I get to work.
My bad - 2005 - integral bearings, etc. Spindle nut holds the whole works together - no bearings to grease, no castle nut, no cotter pin, etc. It all makes more sense now. I wasn't paying attention to his model year.
