When in 4wd if I turn the wheel more than half way the front end will jerk back to half turned so hard that you can't hold on to it. Then it goes back almost to where it was and keeps jerking until it gets back to under half way turned.

It does this really bad in low range

My dads truck does this too except not quite as bad.

Is this normal?

 

I mean where is this happening at and what are the road conditions?

The 4wd system has to be able to "slip" and have its own movement especially when turning or it can bind. The main reason why they say never use 4wd on solid clear ground and especially turning on the road or driveway when its clear. The harder you turn, and thelower range its in, its putting even more power/force into the system that can just add to the effect.

So where was this happening, on loose dirt and mud, or like on a clear parking lot/driveway? Big difference.

 

ZWilson07 is right if this is happening on a paved road then its normal

 

Well, I use low quite a bit backing up trailers slowly or pulling a trailer in a field to save my clutch Because my truck is a 5 speed with 3.55s. I do firewood. So its on a fairly hard surface most of the time. I guess I'm going to buy the kit so that I can lock the front axle in by pulling a cable in the cab type deal. Because in high side pulling
my 16 ft trailer I have to slip the clutch pretty bad to take off.

 

This is the kit

Where would I get something like this?

 

I think summit had some and actually if you google it, I think it has its own website setup for it rather than only through vendors.

If its grass or a field then it really shouldn't bind much unless you are really trying to crank the wheel one way or the other. You got to remember the faster you are moving the easier it is for the system to slip. So for instance if your in low, easing off the clutch to back the trailer up, but your going real slow to control the trailer and cranking the wheel back and forth real sharply while still slowly reversing and easing off the clutch its going to bind some.

That is just the nature of it, but if your are planning to use 4low for these types of things, which I myself have done alot or to climb steep grades in the back of our farm your just going to havta try to limit how much you are turning the steering wheel, atleast while just barely moving and from a start and stop. But as long as you wait for the clutch to fully release and you are only working off power from the gear and your actually moving, you shouldn't have much of a problem with the bucking off the system, again PROVIDING that you aren't cranking the wheel back and forth real far.

EDIT: sorry the explanation might be alittle hard to follow, but its just alot to explain and can be kinda hard to visualize without being there in person you know. I would say that jerking when going over half turn is completely normal, especially in the situation your putting it in. Every vehicle will be alittle different, alot of 4wd systems are different, different size tires and types of tires and wheels vs stockers, particular situation the system is in or the angle of degree the vehicle is on, etc.

So again id say what you are experiencing is totally normal and once you get to the point that you've used 4wd systems alot, you will start to notice how things feel and sound and whats normal and whats not. I remember way back before I had ever owned a 4x4 and bought my first one I was worried about if when test driving a vehicle if I would have a chance to test the 4wd and would I even be able to tell if the 4wd system was working. Now looking back all that time and years I think how the hell could I think that I wouldn't be able to tell by the noticeable sounds and feelings that are associated with it all, its just something you got to get used to but from what I can tell from your descriptions, its all good.

Goodluck.

 

With my posi lock not engaged in 4lo with my 4.88's and 35's my truck will back my 16ft trailer up my pretty steep driveway by itself lol.

 

you also have 4.88 and 35's lmao, thats alot different than backing a trailer up with street tires and stock form especially if you were in grass instead of a driveway, but I do agree that being able to go into 2low would be beneficial instead of always having to use 4x4low, but for me that just gives me a chance to use the 4x4 and keep it in all good running form rather than just when I need it during winter or w.e.

 

True but 2lo is awesome, Ive used it to pull boats out of the water and all kinds of stuff. Just to make life easier on my rebuilt trans.

 

you'll love how the posilok provides the option of 2wd low.
