forgiven.

 

thanks for the info.I have a 2000 f250 4x4 with the off road package i know that going from 4hi to 4lo i needed to stop and shift into netural, but going from 2hi to 4hi when i was moving at about 15 mph i got a lot of grinding was not sure if i should do this again...thanks

 

You might want to check the position of your hubs.Make sure they are in the same (auto for now) position. With your truck stopped, rotate the selector to 4hi then take off. By 5MPH you should lock in. If it doesn't work, try it the same way but with your hubs in LOCK. If these fail, try to listen for where the grinding is eminating. If you feel it's from your transfer case, go see your dealer. There are over 50! things he'll have to run a check on. My uneducated GUESS is that one of the hubs is not locking in. Hard to tell from here. Let all of know what the solution was, as well as the problem OK!

 

thanks again i must not had the hubs locked in all the way used today and had no trouble...

 

Cool! Glad it worked for ya!

 

:-X11 Now boys, Lets not knock on the disels being too noisy. Nothing like owning a Ford SD that you can really hear. Chop the muffler off show a pair.

Now on to a question... i trust you guys know your stuff after reading all about everybodys lifts. I just ordered a FabTech 5.5 lift kit for my 99 F-250 v-8. Question how reliable are these lifts on or off road? Also whats a good size of tires to mount up on this baby? I was looking into 33s only becuase of the issues with emisions and there crap. How wide though?

Thanks Boys

dude. 33's will look too small under that lift. you should run 35 or 36 inch tires under a fabtech 5.5. the quality of this lift is superb.

what emmisions issues do you think larger tires will bring you?

 

I'm kinda jumping in late here, but after last weekend I can confirm that only one front tire gets power. I was driving on a "road" on some BLM land in eastern Washington looking for some birds to kill. There was snow on the normally dirt roads. I was in 4x4 and didn't have any problems until I got to a little hill. Part way up progress stopped with tires spinning. I looked and saw all 4 tires spinning on the rear and the left front. Right front was not moving. After a little back and forth, I no longer could move in either direction! Being the old Boy Scout I always come prepared. Used the shovel to dig around the front tires and installed one of my sets of chains (I have another set for the rear). Cruised up the rest of the hill no problem!

Wouldn't you know it, as we were chaining up the truck we hear some Chukar up on the hill. I decided we better make sure we are unstuck before dark. Once I got up the hill, we let the dog loose and went after the birds, but couldn't find them before dark. It wasn't a total loss though; my 8 year old son got to use his new BB gun to "kill" a can of V8 juice. The "blood" was sprayed all over the snowbank.

Not a good idea to do that. I've yet to see a truck that appreciates this trick. I've done it with older gear drive Tcases as it is like shifting a manual trans without a clutch. I'm sure that the Tcase did not like this as there are no synchros to help the shift and every so often I would miss the "shift" and have to shut the truck down to engage 4lo. I would also get the owners manual for your truck to confirm other shifts.

 

HARALD,

Did you have the hubs locked or did you just use the Shift on the Fly. Someone said in an earlier post that if you lock the hubs then both front wheels will spin.

 

If only one front wheel is powered in 4 wheel drive, then, why can't you run it in 4 wheel drive on pavement without front axle bind? I would think that both are powered. Will have to try mine out sometime.

 

As stated above, during normal operation (ignoring limited-slip), only the right-rear and front-left wheels are pulling in 4x4 mode. The "axle binding" is a result of the front and rear wheels not turning at the same speed. As you know, a differential allows one wheel on an axle to turn faster than the other wheel. This is necessary for turning corners when the "outside" tire has to travel further than the "inside" tire. Also, we know that the front wheels do NOT travel the same distances as the rear wheels when making a turn. Because of this and because there is no "differential" between the front & rear axles to allow them to turn at different rates, you get "axle binding".

You should NEVER run your truck in 4x4 while driving on high-traction surfaces. It's a sure-fire way to cause excessive wear on the front-end of your truck.

I just used the shift on the fly. Shift on the fly engages both front hubs through a vacume pulse system and also electrically engages the transfer case. The manual hub lock is only there in case you have a vacume system failure.

It would be nice if Ford had a locker on the front end for times like my trip, but I've never heard of one that gets actuated by turning a dial on the hubs.
