2020 GT500 - Retorque Wheel Lug Nuts

[Snoopy49]

I just checked mine today for the first time at 876 miles and all 20 lug nuts rotated.
My car has never been driven hard or done any burn outs.

Even if you drive like an old lady going to church on Sunday, make sure you check the lug nuts.

From the 2020 GT500 Owners Manual Supplement.

Retighten the lug nuts to the specified torque at 500 mi (800 km) after any wheel disturbance (tire rotation, changing a flat tire or wheel removal).
150 ± 15 lb-ft ---- (200 ± 20) Nm
Note: Torque specifications are for nut and bolt threads free of dirt and rust. Use only Ford recommended replacement fasteners.

Damn good catch, Earl!

Makes me think Flat Rock didn't quite torque to spec as I don't see any other reason that they should have loosened. I'm using Terrance's Ti nuts and when I've checked, they were exactly where I set them. I have 1900 on her with three quarters of that time using these lugnuts.

All 20 check torque wrench calibration ? To uniform to have just backed off.

I used a 250 lb-ft Snap-On torque wrench and it is calibrated. Not all the nuts required the same additional torque. I didn't bother to check the existing torque for each lug nut before I torqued them, but they all rotated when I applied 150 lb-ft. For all I know they may have been torqued to 135 lb-ft which would have been within the spec.

Ok misunderstood the post, strange that happened.

Something prompted Ford to make mention of it in the manual. It looks like it is a one time check until the wheel has to be removed and that resets the clock.

Either way not a bad recommendation to check them. Nope they shouldn't have loosened but you never know and it doesn't hurt.

Thanks for the friendly reminder.

Read the same in mine also, looks like a standard for all.

I work with torque wrenches daily mounting wheels. I discovered this a while back and have been very pleased so far. Before you bash ICON (Harbor Freight) you might want to watch this until the end.

It has always been recommended practice to recheck torque on lugs after 50-100 miles of driving any time the lug nuts have been removed.
