Nothing is the same?
Seems to me that all the 2020 F150s have the exact same vacuum actuated hubs to me as the 2004 had. Yes? No? Am I wrong?
Seems to me that the front diff in a 2010 F150 Raptor is the same part used in a 2020 F150 Raptor. Yes? No? Am I wrong?
Wrong on both counts. The IWEs are a completely different design and part number, along with the reservoir, lines, and solenoid.
The front axle housing on a 2020 is a completely different part number from a 2010. They didn’t just change the suffix, which indicates a revised or updated part. Everything from the casting to the axle housing tube to the axle stub shaft is different. 2010s used a stub shaft and flange to connect the driver’s side axle; on 2015+ models the axle installs directly into the differential.
You are 100% arguing semantics. It's all been essentially the same since they ditched the torsion bars on the 1997-2004s for the coil overs that the 2004+ F150s have run for the last 15+ years. Yeah, the frame is not EXACTLY the same, of course. They have upgraded the steel types and thickness here and there to get better torsional rigidity to keep up with the market. The shock mount moved 3 mm to get better resistance to axle wrap, more suspension travel etc, blah blah.
No, you are making 100% baseless, generalized statements. What “seems to you” or what you want to believe is irrelevant, the facts are what matter.
When the frame was all-new for 2015 (no parts or components interchange), Ford used 77% high strength steel (2014 was 23%), and employed a multi-thickness cross section and through welded crossmembers. Even with the massive increases in rigidity and strength, the new frame was 60lbs lighter than the 2014 due to the use of cold rolled high strength steel.
