Expy for off-roading?

Anything BUT words about the expedition I don’t own

Tell us about your expedition and off roading with it? Why won’t you?

What a couple douches. I wish you’d both go bang some monkeys and get aids. Hopefully it’ll weaken your immune systems enough for covid to relieve us all of this ******** argument.

Back to off roading in my ford. Took it out again this weekend for some light off roading as I’m still in engine break in period. Drives well, although I almost got stuck in some sand in a wash, definitely need to upgrade to lockers.

Thanks to who liked my truck and was talking about having kids, I can’t stand to read thru this entire article again.

I was going to add a Truetrac to my rear of my 2000 before I got rid of it. I have them front and rear in my SAS’d Explorer and they work pretty well. Not as complex as lockers, but don’t work quite as well either. Some trade offs.

What year is your expy and what years did they put lockers in...? I believe the 4th gen w/tow package have lockers?

What’s the true trac ?? I’m still learning

I’d be surprised if the 4th gen has a locker. Lockers are pretty much reserved for offroad oriented vehicles- like the Jeep Rubicon and the offroad versions of the Ranger and Chevy mid size pickup. The 4th gen Expedition more than likely has a limited slip or some kind of torque biasing system.

I had a 2000 that I was considering adding a Truetrac. But I didn’t. Now I have a 2014. It won’t get anything.

A Truetrac is a geared limited slip- no clutches. Basically invisible when you don’t want them, but there when you do want them. Unless you lift a tire- then you need to left foot brake to fool the diff to send power to both sides. It’s all kind of magical since it’s entirely gear based- no electrics, pneumatics, wires, nothing. Just magic. My Explorer flexes so well that I never lift a tire. Snow wheeling, they can act like open diffs and need some left foot braking.

Pretty sure it does in the FX4 and black label Navi at the very least. Could be wrong. Anyone out there know for sure?

Hey, I’ve built my 2000 xlt, I went crazy. I’m still breaking in the engine and trans so I haven’t taken it off-road yet, but I’m very sure it’ll do just fine.

Stock it’s an eLSD that mimics a locker I believe with a quote “locking mode”. Not exactly a true locker like an aftermarket Truetrac that will reliably get you into overland territory but it can come in handy. TFL look an ‘18 Expy FX4 up goldmine hill and the eLSD lock overheated and shut off a few times on the way up sort of handicapping the truck when it got sideways so it hits its limit in extended off roading. If one was a serious off-roader an aftermarket mechanical lockup may be better. A better stock available unit in this segment would be the mechanical G80 found in the GM.

I believe the 4WD GM triplets all come with a G80 locker, at least my aunts ‘19 Denali has it. Unlike the Ford it’s not selectable and does it’s thing automatically.

Huh. The manual states that 4L (only available with max towing package) provides ‘electronically locked four-wheel drive power to both front and rear wheels’. Seems different than just a LSD but maybe not?

 

[craig sargood]

I believe I read recently, that the new FX4 will have locking diffs, lift , tires, skid plates, and I’m sure, a shitload of electronics. Thanks for the likes. I think I’m gonna need to upgrade to those truetracs, I got into a little wash in Mojave, and got 2 tires spinning and digging in the sand, was able to back up and gas it thru. Those truetracs sound nice to have. Do you need to purchase gears separately for those truetracs??? I need to re gear, and getting bigger tires, I have 33 on now, probably gonna do 37-38.

My 2007 Expedition EL manual states the same, that just essentially means it’s locked in 4WD (power split 50/50 front and rear):

Glad you posted this, I'm on the road, and was curious about the definitions provided by the owners manual.

I got the same 07 xl

I'm not claiming to be an expert, but there is a "electronic locking" feature available on some model & years.
Don't know if Expy ever had this, pickup in the video.

I'm pretty sure on Expy's ... 4H & 4L provides continuous power (50/50 I think) to front and back axles (via transfer case). I'm not sure why you shouldnt use it on dry pavement (no wheel slip I guess) but thats the instruction. I always thought it was cornering (left/right wheels have different path length) but now I don't know. Why is 4H & 4L not for dry pavement (all model years)?

on my '18 Expedition I believe it has actual electric lockers. It has the HD tow package. There have been a couple of times that the locker button has gotten pushed accidentally and while making a u turn you could definitely feel the outside tire sliding on the pavement. Very odd feeling. Quickly realized it. Turned off the locker and no more skidding.

Once and for all...max tow package...ELSD? E-locker? Locker?

When you go to turn the front and rear driveshafts will want to spin at different rates. If you are ever in fresh snow you’ll notice after you turn each tire leave it’s own tracks. In 4H the transfer case is locked so when you go to turn the front and rear cannot spin at different rates so this causes driveline binding to release the pent up force. In snow and mud this simply results in slip so no damage done, on dry asphalt this results in clunking and binding of the drivetrain as one driveshaft wants to spin at a faster rate than the other but cannot.
