It's perfectly fine for daily driving. It just means the front axles and diff are engaged and spinning even though the front end is not driven. There is still a diff, so it doesn't lock the front wheels together. Plenty of people drive around on failed IWEs or with IWE delete kits. It's just a...

Ford has a version of the knuckle that doesn't use IWEs, at least on the 2021+ trucks. And the vacuum IWEs got so bad that if the vehicle has repeated IWE issues, they recommend deleting them altogether, the kits exist and are readily available.

Advantages of the IWE: - Increase fuel mileage by not spinning front axles and diff and driveshaft in 2H modes - Decrease wear on front diff when driving in 2H modes Disadvantages of the IWE: - Unreliable, extra moving parts - Extra source of lash in drivetrain IWEs don't affect the stress on...

The new F-150s have an electronically-actuated IWE on some models, and no IWE on other models. The electronic IWEs still have a vent hose to account for air displaced when the collar moves. https://www.f150forum.com/f34/4x4-actuators-502426/#post6952063 The BRaptor is the only Bronco to have...

Brilliant, thank you for the info!

Are these pictures from your BRaptor?? You're correct - the larger one is the vacuum source that pulls the actuator back and disengages the hub from the axle. The smaller tube is the vent that allows the displaced air someplace to go. I will just be an open vent tube somewhere around the frame...

My computer was acting funky yesterday and I was trying to post the thread before restarting. Here's the part I'm talking about: This is clearly a vacuum-style IWE from the F-150. Here's the Badlands from parts.ford.com: No splines on the axle to engage with the IWE, just inner splines...

I remember the press releases mentioned the BRaptor had front knuckles based on the F-150. In watching Autopian's video of the BRaptor, I noticed the old vacuum-style IWE on the inside of the knuckle: Visible at 5:48 in this video: Is this a pre-production or display unit fluke, or does the...

"I" (eye) WE. Integrated Wheel End. Used on the F-150 to engage the front axles to the hubs when in 4wd modes. The Bronco doesn't have them, it just got a Front Axle Disconnect on some models. Ford mentioned that the BRaptor knuckles are based on the F-150. If you look at this screenshot from...

Simple = reliable. You're introducing a whole host of crimps, splices, and components here that add no useful functionality and needlessly complicate the system.

No, you haven't posted any dyno data or proven anything at all. It's notoriously difficult to achieve accurate dyno numbers at low RPMs due to some dynos' inability to hold steady RPM that low, so most dynos start at 2500+. Your point hasn't been proven or disproven. All you've done is commit...

The Focus RS has factory pops and bangs. That's the Focus with the 2.3, that's the Focus I was talking about.

This thing you're doing is exhausting. Just running around on the field putting the goalposts wherever you want without having the fortitude to actually make a statement... Just say, "I don't like how the exhausts sound" or "I don't like when other people do stuff to their cars." Stop with the...

Those idiots with the "pops & bangs" tunes are the idiots with factory stock cars, as that's the way Ford programmed them from the factory. Are you trying to imply that an axle-back doesn't add power? Fast Intentions posted before/after dynos of their axle-back on a 2.7, it made an...

What issues do the valves have with "holding power?" The typical YouTube click bait is in full force here..."500 CHP?" No. They baselined at 296hp/360tq. They topped out at 404hp/498tq. That's +108hp/138tq. Factory crank rating is 330hp/415tq. How do you add 108 to 330 and get "500+?"

Absolutely nothing, because an inline pulling force on a shackle in the receiver is entirely different than a long moment arm pushing force on a ridiculous drop hitch.

I couldn't find the video thumbnail in the video anywhere. Did I miss it? I just saw the red Raptor doing a couple of little jumpies, no yellow one getting two feet up.

Pedantry incoming - the in-tank pump does provide enough pressure for fuel injection, the port injectors run off of the ~60psi from the in-tank pump. But it doesn't provide enough for the direct injection system.

"Deep" comes from cylinder count and arrangement, not exhaust. A 2.7 opened up gets raspy and warble-y. The only way to not sound like a "ricer" is to keep it quiet.

Nope. Can't be done. Exhausts are like kids. You inexplicably like your own, but most other people's kids (and exhausts) are annoying as hell. Every time you see someone say, "I put XYZ exhaust on my V6 and it sounds great," remember that they're the same type of person that will say, "My...
