12mm to 14mm stud dates?

My brother has a 2000 f-150 4x4 with 4-wheel disc brakes and I am doing rotors and pads all around.

I need to know when Ford switched to 14mm studs from 12mm studs?

Thanks guys,

Josh

The change happened somewhere around late '99 early '00. If the truck has the stock rims they should be stamped with a 12 or 14 near the center.

All 2000-up should be 14mm. They changed when they added rear disc brakes I believe.

2000 MY vehicles (excl 7-lugs) manufactured on or after Nov 27, 1999 should have 14 mm studs.

See TSB 03-22-4 available above.
