Default How to tell if you have a forged crank.

97-03 models
The part number for a forged crank is F75E-A176. The 5.4's came with both Cast and Forged cranks. The truly only way to find out is look in the motor, testing with a hammer or other "pinging" tool is not accurate or advised. Even the 03 model year included the cast and forged. It was a lottery pick when you chose a truck.

Thankfully it easy to check by dropping the oil pan.

Information on the crank; WF = Woodhaven Forge.....the Ford plant that made the crank.
The code is cast on the (2nd) journal for Pistons 2 and 6.


Forged on the left.... Cast on the right....
