Get my 7.3 Ford Excursion Unstuck...

Long-time lurker, first-time caller here... And my Excursion isn't actually stuck at the moment. However, I've been stuck in my (in-town) driveway twice in the last couple weeks, once requiring a winch from the neighbor to get out. I need some advice on the order or upgrades to make this stop happening.

A little background... This fall I bought a 4x4 2000 Ford Excursion, 7.3 powerstroke, with a Waste Veg Oil system installed. Aside from a little rust, the truck is super clean and the WVO system runs great, even in the cold. Ignoring the fact that I pour what is essentially someone else's garbage into my modified fuel system, everything else about the truck is basically stock. Right down to the entirely worn out shocks and leaf springs.

Back to my primary concern. I live in Crested Butte, CO where we get a little snow. Roughly 11 feet so far this year. I get stuck frequently in places like my driveway, and this evening I actually got stuck in the middle of the street. This is entirely unacceptable and at least a little embarrassing. I've previously had an '86 and a '95 F250 that would easily drive through 3' of snow with nary a wheelspin. Where do I start to get my Excursion up to snuff?

The issues I see include:

- Open Diffs: I've quickly discovered that despite being 4wd, the truck has open differentials. Or at least the single spinning front and rear wheel leads me to believe so.

- Highway Tires: The truck came with nearly new Firestone Transforce HT tires in the stock 265/76/16. I'm sure they were great for surfing the pavement in Oklahoma where the truck came from, but they seem nearly useless here.

- Old Shocks and Springs: Not really a cause of getting stuck, but something I'd like to remedy at some point.

- Auxiliary Fuel Tank: Again not really a cause of getting stuck... Due to the WVO conversion there is an aux diesel tank mounted mid-ship between the frame rails. It hangs down a little and has its fuel filter hanging in front (right behind the transfer case). I'm not looking for any significant lift, but getting the rig up an extra inch or two and/or adding a skid plate under the transfer case and fuel filter would make me feel a little better.

I'm not looking to make the Excursion into a gigantic rock-crawler, and I want to keep the costs as reasonable as possible. I do want the truck to be respectable in the winter and also be capable of rambling around the back-roads in the summer.

So, where do I start?

PS- I unfortunately don't own the big house in the photo. The garage (full of bikes and skis) and apartment (not visible behind the snow) are ours, and the 1980 F150 is my wife's. The rest is a vacation rental.

You could buy my 04 Superduty and swap in the axles, both of which have ARBs and 4.10s. Also some other pieces which would bolt right up. :sombrero:

Ha! And what do I do with the rest of your truck? Seriously, that would be sweet, but probably not in the budget.

Tires will fix your stuck problem more than likely. I would go with duratracs personally, they were my favorite when I lived in Gunni. I also have a set of general grabber AT2s on my montero that are phenomenal in the snow, but know nothing of the E-rated version.

Sidebar I drove by your house this weekend, apparently I was checking out your wife's truck!

Whoa, small world! Do you still live in Gunni? We do talk about selling the F150. It's occasionally very convenient to have and (in our opinion) kinda cool, but it spends most of its time just sitting there. Its 4wd with a straight 6 and 4speed manual... If your interested ;)

Duratracs are the other tire I'm considering along with the Coopers. I'm mildly concerned about the DT wearing out quicker and getting worse mpgs.

New tires and lower tire pressure. Make sure you get E rated tires- our trucks are pigs. Make sure your hubs are actually engaging. The stock ESOF auto hubs are known to fail. I replaced mine with manual hubs.

Budget lift to raise it a couple inches and improve ride quality is to swap in super duty leafs (front V codes or X codes- X codes are stiffer, rear "modified" B codes).

Feel free to check my thread or google "excursion v b swap" and you will get a ton of results. After my installation I installed 285-75R17 (~34s) with no issue at all. Unfortunately I don't have any seat time in the snow with this setup.

I'm jealous of your engine.

I have it listed for $6500 locally. That's in Canadian Pesos, exchange rate is $0.75USD = $1.00CAD.

It's tongue in cheek, but still an option

That's a great price on your truck. Manual trans, bulletproofed 6.0, D60, and some good upgrades, wish I had found it 3 months ago. The WVO conversion would have been a cinch compared to putting all that stuff in.

My guess is the electronic shift on the fly (ESOF) hubs are not engaging and its actually still in 2wd.........


If it is equipped with ESOF and most all are, it is most surly the problem and very common. It uses a vacuum pulse to lock and unlock the hubs and after years of rot all the hoses and seals are bad so it will not lock the hubs.

You should be a be able to lock the hubs in manually.

Can I spin the center of the hub by hand in the same fashion as my old manual hubs?

I do have the ESOF hubs, and that may have been part of this evenings difficulties. However, the last time I was stuck I had one front wheel spinning and one back wheel spinning... In my shoveled driveway. :(

Hey youve got the same year and motor as me :) So first things first. The excursions aren't fantastic in the snow. Testing mine the other day I came to realize that. Sure the open diffs don't help (you may have a limited slip rear like mine) but in general ive heard three other people echo that their performance in snow wasnt phenomenal.

Order of things to help fix the problem ON A BUDGET

1. Good winter rated tires - no mud terrains!
2. This is key. If you're getting enough snow to get stuck then air down a good bit. 25 will be fine but you can go lower if needed, just be sure you air up if going over 45-50.
3 / 4. If you're getting stuck due to the snow hitting the body or rubbing against the undercarriage, swap to a different code spring and new shocks. It will assist in your clearance.
If you aren't getting stuck due to height, invest in some maxtrax instead of suspension. (though you really should replace it eventually) If the aired down tires wont get you through the maxtrax will and they make getting unstuck a quick job. Throw them in the back and when you get stuck toss them in front of your wheels. Easy. I use them to help neighbors all the time.

Once again this is the budget list method and excludes things like lockers, winches, etc. The tires alone should be enough to get you through when aired down, but I would HIGHLY recommend some maxtrax if you're regularly driving in that amount of snow.
