Sure wish Ford would offer the 5.0 on the Expedition,Which F150 engine would a Ford Technician pick?

[JExpedition07]

So the 6.2L is here to stay and remains the standard powertrain......7.3L is being added between it and the 6.7L PS diesel.

Power ratings not yet disclosed.....my guess would be 420+ horsepower/ 500+ LB FT....

Wouldn't be any problem with the rear suspension axle if they would have left it alone in the first place and not changed it to Independent rear suspension. It's a truck. Just like a Lincoln Town Car. It should be rear-wheel drive with a solid rear axle.
But see, they can't do that. Just that they can't leave out the video screens cup holders and Wi-Fi. Too many people are suckered into wanting them. At least those items make things convenient. It greatly pissed me off that I had to get independent rear suspension on the used Navigator I bought. I didn't want the first generation because after having an expedition it looked like the same vehicle inside. The 03-06 is my favorite interior design. I can't stand the 07 with the stupid retro 67 Galaxy ugly-looking Dash!
All the independent rear suspension does for me is calls me worried and it will cause me expense if I keep it long enough. I can almost guarantee that a first-generation I can change the gear lube one time and never have to think about it again no matter how many miles I put on the vehicle. On the newer design I will eventually have to replace a stupid half shaft that shouldn't exist. Because I boot will eventually split and it's basically cheaper just to throw a new half shaft in an easier than it is to put a boot on. Then let's not forget the hub assembly that would never have to worry about on a solid rear axle. Stupid stupid stupid all because people are convinced we have to use the latest and greatest technology designs in everything. I even buy old vehicles and I can't get away from the crap.

IRS is better for off road traction than a straight axle.

But it didn't piss you off enough to go buy an Escalade, with a solid rear axle and big V-8? Or even a Land Cruiser with a solid FRONT axle?

A huge reason why Ford and others went with independent suspension is it cuts way down on the chance of a vehicle rollover. That and way better ride quality. A solid rear axle that can't flex like an independent can during a sharp turning maneuver will fight, and have a tendency to flip. These are top heavy vehicles, especially lifted 4x4's. As you guys know, my 2nd car was a solid axle 56 Volkswagen bug. It was a nightmare if you turned it too quick in wet weather, then it got traction on dry ground. I had a situation one morning with 2 other friends, where that wet, then traction scenario happened. I freaked. Luckily my friend Tom sitting next to me grabbed the side of steering wheel, he was pinned against door. His grabbing of wheel countersteered the car, slamming it back on all 4 tires. No, I'm a firm believer in independent suspension. Whatever off-road ability it gives up, is outweighed by it's safety in a dangerous situation.

The New Ram Pickups went with independent rear. The ol' leaf springs from the horse and buggy days were tossed on the junk heap.

Having said that ... My '08 Mustang has a solid rear and it is dialed in that I see no negatives on the race track. It is all how it is put together.

Independent Suspension is not better off road. A solid axle provides much more wheel articulation to prevent airborn wheels and IRS gets hung up and stuck on the control arms. There is nothing better about our IRS for off road.

I said that solids are better off road. But problem is we drive vehicles that are capable of 130 mph plus on the newer 400 hp Expeditions. Even my old 260 hp Eddie Bauer would probably hit over 110 easy. Way too fast for a lifted truck based Suv. I've never been over 80 in the four plus years I've owned it. People that buy the Expedition, buy it over the competition for a few reasons. Ability to carry eight people is top of most people's list. That and it rides great, handles through turns incredible for a 5400 pound vehicle. And 3rd, it rips ass, when you mash the throttle. Ford probably could do as gtncpa said about using a solid axle, and make it handle. But IRS just made more sense, both for safety, and for ride. These vehicles were never meant to climb a hill, like a Humvee. It's amazing they do as well as they do.

Funny how you guys think that a solid axle is better for off road when in the OHRV community, IRS and IFS are top selling points as the individual wheels maintain full traction contact on un-level surfaces.

I think you meant that the new Ram pickups have coil springs in the rear with a solid rear axle.

I think it's pretty well documented that solid axles typically have better articulation for off road duty, and are easier to add suspension lifts without having to change control arms, etc. I love my Expedition, but fully realize it has poor suspension articulation and easily lifts a tire in off-camber situations.

I have a MAX 6x6 ATV -3 solid axles and about as good as it gets for off road operation. It also floats and propels via tire tread.

My old dune buggy was a solid rear axle, great fishtails with that one.

I think we need to have a hill climbing contest. Solid axle vs independent. Any 2 of you guys live in same or nearby town? One with solid expy, one with IRS.. My buddy had a new 73 super beetle, I had the old 56. We drag raced through the dirt lot next to my mom's house. I had 40 hp, he had 65 I believe. We both kept a tie the first 40 feet. Ah the good old days.

Silly me, I thought the IRS was all about having a place to put your feet and more head room in the third row. At least that's why I bought the 2003 to replace the 1998 Expy. I'm not a big off roader so I never noticed the difference being debated.

I would hazard a guess (anybody have the data?) that the VAST majority of miles an Expy is used for are on road … soccer Mom type of trips where third row space is the marketing advantage. The Expy isn't "really" an off road King with mods (or even with) is it?

Sounds like an awful lot of people keep it in 2WD for most of its life too.
You can save 1/16 of a GPM doing that, at least that's the theory.

So many buy a 4 wheel drive for bragging rights. That once every two years here in the Bay Area, when they go to Lake Tahoe. Back East, and mid west it's mandatory, here in San Francisco, it's for posers. Only reason I've got one is that's what my neighbor was selling. If I could, I'd prefer the 2wd.

I am in Austin TX. I use 4WD on boat ramps. We also used it once in mud and on a trip to Big Bend for some of the trails.

Hmmm ... Not the first time in life I was wrong. When I read they were using coil-overs I must have assumed IRS. A buddy of mine has a 2015 GMC Denali and a 2017 Expi Limited. He does "truck stuff" with his Denali. (plows snow and some other things) When he drives to Florida he takes the Expi. He said it handles much better on the highway. He does use the Expi to tow as he touts the torque of the EcoBoost.

In 2020 it looks like the GM full size SUV's will have an IRS. (got this from looking at spy photos of them testing them.)

Well this sure strayed off topic to axles and 4x4....

It usually does. After 40 or more posts, you forgot what the reason for the post was.

Kinda like after 40 or more BEERS

I think my record was 13. I'd laugh when my new boss said I think I can drink beer faster than anyone. We went to a bar in the mall we were working, and showed him he was wrong. Part Moose, part Camel.
