2017 Lug torque spec

[theoldwizard1]

The book says 162 lb. ft.  My torque wrench only goes to 150 !  Why so high ?

 

Mu old '98 E150 say 100 lb. ft.

3+ years on our 2016 SEL & I've never torqued them over 105 ft/lbs. You'll be fine going lower than recommended spec. I believe that a lot of dealerships don't torque the wheels much past 110 ft/lbs either.

So you think Ford just changed it for fun?  I believe the reason is they use larger studs on some wheels with larger nuts and they do need more torque.

 

It's not like there is some benefit to going way below the recommended torque such as ride quality.   I'd get as close to the factory spec as possible.

Admittedly, my old '98 E150 used 1/2" "course" thread buts.

 

The Edge use M14 (0.549 almost 9/16") and I think they would be classified as "fine" (1.5 mm) threads.  Fine threads can handle more torque.

From previous discussions the difference seems to be M12 vs M14 nuts.  M14s are 162 lb/ft.

 

You’re an old Ford engineer - would you follow the factory recommendation on engine bolts?
