I recently purchased a 2003 King Ranch SuperCrew and now that I have a couple hundred miles on it I wanted to check the torque on the wheels. I looked in the owners manual and it said for 5 lug wheels 150 lb/ft torque, I thought that sounded high since the specs on our Crown Vic aluminum wheels is 85-90 lb/ft torque.

Does anyone have the correct torque spec, I don't want to damage one of my wheels, I imagine they cost an arm and a leg.

150 ft/lbs is the correct spec. Take a close look at the lug nuts and you'll probably see the torque spec stamped on them. The Crown Vic probably has smaller studs.

 

damn, 150? I barely have the strength (and traction ) to torque my 100 (98 f150) how the heck are you supposed to do 15?

 

Use a long torque wrench.

 

I owna 97 and they are only 100 Ft. Lbs anyone know why they increased it so much over the previous ? I know they change the thread size form my 12mm to 14 mm is that the reason behind the increase those 14mm handle more toque?

The 14mm studs are the reason for the higher torque spec.

 

Yep kind of figured that had to be it.

Jayhawker.... If you don't mind my asking, where did you find the torque spec in your manual? I've been through mine a couple times and can't find anything relating to torque specs.

For anyone / everyone else out there, would you think my lugs should be torqued to 150 lb/ft since I've upgraded to 18" Lightning wheels with 14mm lugs? I'm curious, because I've been running them at 100 lb/ft. Anyone?

 

The tire torque specs in my 03 F150 manual is on page 184.

Hope that helps you. Jayhawker

 

OK, so the wife is out with your truck to pick up a dresser she found on Craigs list for a song, great deal. On the way home she gets a flat.

"Honey I have a flat and I am on the freeway"!!!

"No Problem dear, just jack up the truck and put on the spare"

"Is that hard to do?"

"No you just walk down the highway till you see a farm, wake up the old farmer and ask him if he has an 18MM 1/2 inch drive or larger breaker bar, Deepwell socket for same, and a 4 foot long pipe to loosen the lug nuts, Nothin to it"

I guess the guy at ford that designed the spark plugs for my 5.4 litre Triton designed the lug nuts too.

 

All '97+ I wanna say are 150lbs+, 2001+ for sure is. Its for the brakes sakes. improperly torqued lugs can lead to warping rotors and unstable driving. Miles and miles of orbiting with offset weight balances, not good. I learned that the hard way.

 

Negative

1997-2000 with 12mm lugs is 100-Ft.Lbs
2000- Current wiht 14mm lugs is 150-Ft. Lbs.

 

They actually changed in 2000. I believe some of the early 2000 models ha 12mm and the rest of the year had 14mm.

 

Yeah I knew it was a mid year change, but I thought it was 2001

 

Thanks for informing me .
