I just meant not to take advise from the person that said you cannot go in reverse in 4-wheel drive, sorry for the confusion. Also, you said "the differentials won't turn the inside wheels slower than the outside wheels" (while in 4-wheel drive), you also mentioned that the differentials "disengage" (when in 4-wheel drive). Those previous comments are not correct. The inside wheels still turn slower in 4-wheel drive. But, because there is no differential between the front and rear axle, like all-wheel-drive cars, turning will not be as smooth. Although, correct me if i am wrong, but if you do not have an open diff, and you have a limited slip, then when in 4-wheel drive and turning, the axle with the limited slip will lock.

 

so THATS what 'wheel hop' is dammit red!

 

Yeah, your right. I'm not sure why i said that.. but i'm under the impression that when you put it into 4 wheel drive, they differentials lock together.

 

glad everyone could come to an agreement....

and im curious to understand your statement..

this is the first ive heard of the PCM having anything to do with type of input from the steering system.. could you explain?

 

Looks like Shott beat me to it again ... that was MY question ... dammit!

 

sorry bill! i am curious tho.. always interested in learning new stuff!

 

Thats not true at all unless your shafts and u joints are made of plastic...

You can turn while in 4wd on any surface, although it does cause binding in the front the more traction you have. So on dry pavement it causes a good amount ot binding in the u-joints, but thats it. I really doubt you'd break one unless you had it at full lock and floored it.

People wheel Dana 44's with 37" tires which is huge forces on the shaft and joint and generally don't have a problem, except in extreme conditions.

Its a common myth for (no offence red9535) uneducated people to think they're going to screw up the diff or transfer case by taking a sharp turn on something like dry pavement. Its not really good for it, but the binding is caused at the axle u-joint.

The computer doesn;t control anything in teh differential either. Whether your in 2wd, 4hi or 4lo your diffs are totally seperate. The front is an open carrier, meaning the tire with the least resistance gets the power. So if one tires on pavement, and the others on ice, the one on ice will spin all day long and the one on pavement won't help at all.

The rear however usually has Limited Slip in the rear, which uses clutches to try to give both wheels power, but in severe differences in traction, like on wheel on tghe ground, one in the air, the clutches don't have enough stregnth to lock together, so the one on the air will spin and the one of the ground will hardly do anything.

A locked differential completely locks both sides together, no matter what. One can be in the air, one in a mud pit and both wheels will spin the same speed. There are full time lockers and selectable lockers which can be turned off, and when they're off they act like an open diff.

Anyways, going in reverse it totally fine. Also your diffs don't change in 2wd, 4hi, or 4lo.

 

I think I love you jason..

lol [sm=roll.gif]

 

Haha not trying to come across as a dick, I'm just in a "tell it straight foward" mood

 

back to school yet are ya?!? lol
