That's too fast Steve. You are at the edge man. I do not want to know if mine does that or not!

Almost completed the Towing Pkg. options, MOD's so far: K&N air box mod, Gibson Super Truck, clear Bugflector II, Leer TSC 600 hard cover, Bridgestone Dueler OWL ATP 265/75 R-16's, TrailMaster Invader N7 shocks, Smittybilt step bars, Ford moulded mud guards, "White-white" head lamps, Cloud Rider Design's SS Grill and bumper opening, Bosch Platinum + 4's, Hayden 30K+ Tranny Cooler, Superchip on the way!

 

I also have an '88 ranger and in 4x4 you can tell a slight vibration, the more miles it gets the worse it gets (170,000 now). Last week I accidently shifted my F-150 into 4x4 and was driving up to 70mph on dry pavement and I did not realize I was in 4x4 until I made a slow sharp turn on blacktop, at which time the front wheels started their normal bucking, there was no difference in vibs with this truck at any speed. (The elect. shift **** is right beside the heater fan control and I turned the wrong ****.)
My son has a 2000 XL and there also is no difference between 4x4 and 2 wheel drive vibrations in his at any speed.
I would not shift into 4x4 at speeds over 35mph but I don't think there is any problem running in 4x4 at speeds up to 70 as long as the roads are safe to do so.
I have heard of one case of severe vibrations and grinding while shifting into 4x4 with a new truck. The factory installed one tire of a different size than the other three. You may want to check this and air pressures in your tires

Steve g it looks like your truck is similar to mine except mine has a silver bottom. How do you like yours, mine is the best vehicle I have ever owned. As soon as the snow and ice melts I will take this truck to it's top speed and I am certain it will be just as smooth there in 4x4 as it is in 2 wheel drive

Steve,

You missed my point. If it's slippery enough to need 4H it's too slippery to do 55. Just my opinion.

 

I'm not an expert but it seems to me that if they have the 4wd Auto in the Expeditions etc. then it must be ok for the 4x4 to go into gear at higher speeds and to operate at higher speeds. I will agree that if it is slippery enough to use 4x4 then you shouldn't be doing 55 but I use it when it is snowing. i don't have a problem going 60-65 when there is 6+ inches of snow on the highway. Remember, 4x4 doesn't work on ice! it's funny to watch all the yuppies in their new S.U.V.'s go flying down the freeway at 70 when it's icy cuz you always see them in the ditch a few miles later!

Oh man. You guys driving your trucks at high speeds in 4x4 on paved roads... What are ya think'n? Never mind the mechanical stress that's being placed on the drivetrain that's not designed to be driven in 4x4 on paved roads. Instead, think about the handling characteristics involved.

Our trucks don't have the A4WD position like the Expi/Nav does. Our transfer case is very different. When you put our trucks into 4WD (4Hi or 4Lo) mode, it locks the front and rear drives together. There is no slippage between the front and rear axles. Going straight ahead, you won't feel much if any handling difference. However, when you turn that wheel, like on a curve or in an emergency, if the 4 wheels have good traction, you run the risk of losing control.

When I'm hauling butt on winding dirt roads, I'm always in 2WD mode because handling is predictable. When in 4Hi, handling is not predictable at high speeds because of the changing road surfaces. Having that front wheel grab when you don't expect it can set your heart beating. Severe understeer when in 4WD is common. There are some places that I frequent that I cannot make the switchback while in 4WD while I can do it in 2WD.

Now, if our trucks had full time 4WD, it would be a different picture.

Dennis, Thanks for the setting me straight on the difference in transfer cases between the F-150 and the Expiditions. So, is it alright to be doing 60 down the freeway in 4x4 when there is 6 inches of snow on the road and no possibility of getting traction to one tire but not the others?

In that case, I'd probably try 4x4. On the other hand, I've never driven in snow, so I'm not the best person to be asking this question. However, I'd have to say, the time to use 4WD is when you don't have any pavement under you. One concern I have is the ABS. Does it work in 4WD? I never thought about this aspect before.

 

In terms of shifting into 4-HI, I believe the manual says that it is safe to shift into 4-HI at speeds up to 45. In terms of actually driving in 4-HI, going 60 or 65 shouldn't be a problem (check the owners manaual).
Here's the general rule that I follow. You have more leniancy in terms of using 4wd when you are driving on roads where little turning is involved. So on the highway, I would be more likely to use 4wd because there is less turning involved and less of a chance for the drivetrain to get bound up. At highway speeds, things can go wrong a lot faster, so having a little extra insurance is nice. If I was driving around town and the roads were not that slippery, I wouldn't use 4wd. There's too much opportunity for binding up the drivetrain. Besides, you aren't going that fast so it is easier to handle the vehicle, and you can always put it into 4wd as you need it.

The use of 4x4 on the road when its raining? Hmmmm. I've always thought 4x4 was for going places 2wd's can't. If you need 4x4 to drive on wet pavement, then maybe you might want to invest in front wheel drive, AWD, new tires, or driving lessons.

 

I guess a couple of us didn't make ourselves very clear about this one point. If you find the need for 4WD at high speeds because of slippery conditions, then you probably won't be able to stop your truck safely.

As with any driving situation, it's even more important that you can stop safely. I'm not sure if ABS still works in 4WD mode. Can anybody driving in snow let us know if 4 wheel ABS still works in 4H?

 

Yes, it still works but I am not driving fast enough to need it if its slippery. I think we are just going to have to agree to disagree on this one. I'm not here to change anyone and don't expect to. I for one slow down first before ever thinking of using 4 wheel drive.
