I see that everything on the forum is directed towards 4wd. This seems natural for an off-road site. What I want to know is ... where do the AWD vehicles fall in the trail rating spectrum?
Mine has the Ford 8.8 rear dif w/ 3.73 limited slip and a Dana 35 front dif.

Uh, the great AWD vs 4WD debate.... To paraphrase from the Subaru forums: 4WD provides power to front and rear differentials through a transfer case with high and low gear ranges. If differentials are "open" (no lockers or limited slip), then power is truly provided to only 2 wheels. AWD is generally a full-time system that is electronically controlled. Generally this system uses the brakes to slow down a spinning wheel to transfer power side to side and an electronically controlled center differential to transfer power front to rear. Notable differences are the lack of a transfer case, and thus no 4hi, 4lo, or 2wd selections, and all the added electronics (sensors, computer, etc.). I couldn't tell you how AWD falls in the trail rating system. Back east my Subaru would run up hills in the snow that full-size 4wd trucks had trouble with. I never tried rock climbing with my Subaru though. I would think that with a bit of lift your truck should do just fine.

Main question here is, do you have an option to shift into 4-lo? There are many a 4x4 out there that are AWD, but a lot of them do not have the ability to shift into 4-lo. Take for example the coveted Toyota FJ & FZJ80 series Land Cruiser. AWD, but do have a transfer case to shift inot 4-hi and 4-lo, and even some of them have lockinf diffs front and rear (very hard to get a hold of). Also, take into consideration the Land Rover Discovery series or the Range Rovers. Same set up almost, but on most of them you can select 4-lo, and most have a CDL (Center Diff Lock), same as locking front and rear diffs, but instead of a "traditional" transfer case, they have a center differential. Also is said to be true of the (my dream expedition rig) Mercedes G (or Gelandewagen) Series (popular inthe states for the G-500 model). Full time 4 wheel drive, but comes with 4-lo, and 3 locking differentials (rear, cemter, and front). It all depends on your vehicle. My friend has a 94 Jeep Grand Wagoneer 4x4 with full time 4WD, but he can switch it into 4-lo, but does not have the option to lock any of the diff's. Also, to answer another part of your question, your truck should not have a Dana 35 in front..... You have an IFS set up (or should with your year Moutaineer).
Does that help at all? I have had a bit much to drink tonight, and am not sure if I am making any sense.

Wait, you said Dana 35 front diff, not axle. Sorry. Does Dana make just Diffs? I am at a loss at this one. Some help here please?

No, I do not have the IFS. I am still running the torsion bars. Everything I have located says that it is a Dana 35 front diff. Working two jobs gives me little time to get into the rig the way I should.

Yes dana does make diff's. I have the 77 chero and it was awd when bought and came with a low range unit.Now it's part time with work to TC and hubs. Also to go with the dana question you can still buy the dana limited slip can't remember the name of it.

That thing doesn't have IFS uh? Are you sure. I can see the dana 35 diff but no IFS i don't know. My dad had 97 Ford Explorer and if I remember correctly it had IFS. But I may be wrong I going to research this real quick.

But I may be wrong I going to research this real quick. Actually no...it probably does not have IFS, but rather a TTB front axle, which is better than IFS, but not as good as a solid axle. A TTB front end is also known as a Twin Traction Beam. It uses radius arms to locate the axle and the axle basically pivots in the center.

I have been trying to say that, I do not have IFS. They do not have torsion bars. But I am glad to hear that I am in the middle! We all have to start somewhere. I have always done the off road thing with 2wd cars and trucks. Nothing serious.

And my wifes Suzuki sidekick(2wd) was good there was only a few time I need a few friends to stand on the back bumper and jump up and down, so I could get the traction I need because I chose a bad line ;D
