I don't torque my wheels. I think a 300lb compressor with the impact gets them on tight enough ;-)
Go read the thread from a few weeks ago where a Super Duty owner was towing a trailer across the Bay Bridge in San Fransisco and all his lugs sheared off of a rear wheel. He lost a wheel, he suspects because he rotated his own tires and overtightened the lug nuts.
He managed to get the truck and trailer off of the bridge without hitting anyone or anything, not sure how but he did.
From the factory service manuals for 2000-2007 the spec is: 8-Lug M14 wheel bolts 224Nm or 165lb-ft for alloy or steel. You do have to use the correct lugnut type for each type of wheel of course. By the way, over torquing is very bad - 'bout garantied to have a bolt shear at some point. Over-torqued lug bolts should be replaced ASAP.
Please forgive me for jumping in this thread, but Hey, now got some answers for a thread I started a few weeks ago, but now,,, is there a difference in lug nuts for each factory type of wheels on an 07? Will the steel factory lug nuts not work on the factory alloys? I did it on mine - do I need new ones?
Not positive on the steel vs alloy lug nut being different on all models / years. I do know that on most of the SD model years they are in fact different. The ones for alloy have an integral washer whlie the steel don't. Do NOT use the wrong ones. They will not work properly and are dangerous if used on the wrong wheel type.
jake00 - If yours are stock alloy wheels they should be 165lbs according to the book. Check with a ford service center to be safe.
