Why150ft/lbs? Seems a bit much. And how to torque that high when no sockets fit?

 

Because that's what the highly paid engineers at Ford deemed necessary? Get aftermarket lug nuts from Gorilla or some other reputable company and problem solved.

 

a) why? Because the Ford engineers said so, and in the absence of evidence to the contrary, I'm assuming they know what they're doing (or I wouldn't have bought the truck)
b) a 21mm socket should fit; if it doesn't, see the swollen lug nuts thread about why the two-piece lug nuts suck

 

You can buy an impact flip socket on eBay that's 21mm/21.5mm, that might work...but make sure you get replacement lug nuts before you bother messing with the swollen ones.

 

As mentioned above... and keep in mind they are testing the wheels and lugs to fairly extreme federal standards (loaded to gross weight, probably with a trailer, with substantial lateral acceleration - more than you will ever get out of the truck in the real world). They are engineering for when the truck gets hit... not just enough to keep the wheels on going down the road.

 

My sockets fit fine. Maybe you need a better socket?

 

Geez, are we really turning into wimps? Second thread like this in a week. The manual calls for 150# for a reason, the engineers don't just pick a torque number for fun.

And like I said in the other thread, if you can't handle 150#, don't buy a Ford Edge.

 

I don't have a 21mm socket either but a 13/16" works just fine!

 

Seems like Ford has revised this slightly. This is from 2016 OM. (not significant difference)

 

My replacement Gorilla lug nuts also specified 150 lb-ft.
