theoldwizard Posted April 18, 2018 Share Posted April 18, 2018 I am interested in any data/drawings/video of the 4wd unit used in the current F150. This is likely going to be the same/very similar to the unit used in the Ranger and consequently the Bronco, Explorer and Fusion. I really am curious how it is connected to the transmission and how the power ts delivered to the front wheels. Please post links. 1 Quote Link to comment Share on other sites More sharing options...
YT90SC Posted April 18, 2018 Share Posted April 18, 2018 The current F150 uses a transfer case just like they always have for time eternal which is nothing like the FWD based units you listed. Chain driven front shaft, electronic clutch for engagement, shift collar for gear reduction for 4LO. It is bolted to the rear of the transmission and gets power from the output shaft of the transmission. I can only assume that the Bronco will use the same. The front driveshaft will only turn when the clutch engages or the IWE style hublocks are engaged. The current Explorer, Fusion and all other FWD based units use a PTU attached to the side of the transmission on the right side. It is splined to the case of the differential for the front wheels. They use gears, not a chain. It is constantly spinning a driveshaft to the RDU. The RDU has the rear differential and a lockup clutch built into it.

YT90SC Posted April 18, 2018 Share Posted April 18, 2018 (edited) Youtube "Transfer case operation" The Toyota case works similarly, the current Ford case uses an electronic clutch instead of the engagement fork.

akirby Posted April 18, 2018 Share Posted April 18, 2018 He as referring to the new Explorer which will be RWD on CD6 and possibly the Fusion replacement. Quote Link to comment Share on other sites More sharing options...
YT90SC Posted April 19, 2018 Share Posted April 19, 2018 Akirby, He asked about the F150. There is zero new tech in the t case in an F150. IF Fusion goes RWD, it will probably use a viscous coupler like the 5.0l Explorer or a fully electronic clutch system. Either way, it WON'T get a low range system, which I fully expect Bronco and Explorer to have. I imagine they will be gear driven, rather than chain for the front.

I guess that is kind of what I am getting at. So in YT90SC's opinion, the Ranger, Bronco and Explorer will all get the same transfer as the F150, but the RWD CD6 Fusion, if it has an AWD option will get something different (which also would work well in the Explorer). My guess is that the biggest engine available in the Ranger, Bronco and Explore will be the 2.7L EcoBoost. Aviator might get the 3.0L EcoBoost. (My gut says the 3.5L EcoBoost will be reserved for the F150/Expedition.) If those assumptions are correct, isn't that transfer case a bit large/over capacity ?

akirby Posted April 19, 2018 Share Posted April 19, 2018 3.0T has already been confirmed for the Aviator. Quote Link to comment Share on other sites More sharing options...
YT90SC Posted April 19, 2018 Share Posted April 19, 2018 Wizard-- -yep. But T-cases are scaleable easily and the current F150 case isn't physically very large so they may just use what they currently do. In the old days they had smaller cases for Ranger, Explorer and Bronco 2 though. I imagine if one wanted to search, the current cases are the Borg Warner 4467 for TOD F150 and the Borg Warner 4469 for ESOF F150. 1 Quote Link to comment Share on other sites More sharing options...
theoldwizard Posted April 22, 2018 Author Share Posted April 22, 2018 Ranger, Bronco and Explorer at "sit" high so working a differential and front axles should not be too difficult, Fusion and possibly Mustang are another story. How are they going to get a diff and front axles in there with a North-South Engine without pushing the engine up through the hood ? Quote Link to comment Share on other sites More sharing options...

The same way FCA does it with 300/Charger/Challenger Quote Link to comment Share on other sites More sharing options...
