I realize that. And, if you read the specs you posted, about the F53/F59 , you will see the front axle listed as a Solid I Beam. That means a single one piece axle, NOT a Twin I Beam as found on the E350/E450.
Don't want to get into a pissing match here, but the FR3 is built on the F53 chassis, and has a one piece axle, NOT a twin I Beam.
