Sam -- On mine, its 150 ft lbs. The torque specs are actually stamped on the lug nuts.

Re: What is the torque specs for the lug nuts?

Ford sent out a notice to the original owners that the spec had been increased from 150 to 165 ft lbs. My truck came with the 150 ft lbs in the manual but was upgraded with a notice to put in the manual that the new spec was 165.

Re: What is the torque specs for the lug nuts?

Interesting. I have received no such notice from Ford for my truck. Given that yours is a 2002 and mine is a 2005, I wonder what Sam's proper torque spec should be as his is a 2004. Maybe his best bet would be to call a Ford dealer and ask about his particular truck.

Re: What is the torque specs for the lug nuts?

Yeah, my manual has that page edited. There is a sticker covering that page that completely replaced it. I noticed it right away because the page was so much thicker.

Old: 2006 F250 XLT, Ext. Cab, LWB, FX4.

Re: What is the torque specs for the lug nuts?

Check with the wheel manufacturer.... Just a very few months ago I had one with tapered seat lug nuts and an instruction sheet from the wheel manufacturer stating 80 ftlb. Not my cup of tea but, with a photocopy of the instruction sheet stapled to the hard copy, the wheels got 80 ft/lb. The ball, if needed, is in the wheel manufacturers court...

At the same time, I recall another 250 with aftermarket wheels and tapered seat nuts that kept coming loose..... the nuts weren't deep enough to fully seat in the wheels and bottomed on the ends of the studs at just the wrong spot.

Caveate emptor....

Re: What is the torque specs for the lug nuts?

Don't the instructions read "put a small drop of oil on the lug nut where it rotates on the washer and then torque to 165 ft lbs"??
