Hi all,
So, I have been using a 7/8" socket for my 2024 F250 4wd Platinum crew cab. It has always been a little loose, so I ordered up the 21mm socket. Won't fit over any of the lug nuts. I put a 22mm on them and there is the same play as a 7/8" socket. So what the heck? a 21.5mm socket that isn't produced? Is this because of the special Ford capped lug nuts? I use an impact gun to just snug, then 165# torque wrench. Maybe I should stop being so perfect with the tools...

Cheers

 

21mm fits your lugs. Capped nuts have swollen most likely

 

You can easily get a 21.5mm on AMZN for just this reason
.

 

Caps are most likely swollen and are ready to pop off. Ford has had this issue for decades and still insists on using them. Many folks swap them for "regular" lug nuts.

 

Yup I had the same happen on my f150, as soon as they are swollen they get replaced with solid lug nuts.

 

In the past, when I've run into a "snug" lug nut, I've tapped a 21mm socket on to "resize" it...loosen the nut to the point where its still on the stud by several threads and pull the socket off.

 

Is there a replacement lug nut that has the general consensus of being correct without the OEM swelling issue?

Mcgard, Gorilla, etc....

 

McGard is the only US manufacturer of lugnuts. Just make sure whatever you buy is not a stainless capped version. They are triple nickel plated and pretty much never rust or fade.
