Replacing transfer case chain???
My truck that I just bought today seems to have a hesitation then it grabs. It only does this when you are maintaining a costant speed around 25-40mph. The neighbor is pretty sure it is the transfer case chain. There is a little play in the transfer case when I twist the drive shaft and you can hear it in the transfer case. Does this sound like a possibility?
Note: The truck is a 92 F150 4x4 with the 300 I-6 and the E4od tranny. Not sure the type of transfer case

It only happens when I am maintaining a constant speed around 25-40 mph. If I accellerate or coast it doesn't do it. The best way to describe it would be it is almost bucking, but very little. I would be willing to be 95% of people wouldn't even notice it (I tend to notice every little thing to the extreem). Almost like on a stick when you start off (and you don't know how to drive it) and accelerate and it bucks a couple times, but not nearly as bad.
Like I said, it is a very minor hesitation, and could be a miss. There were no codes, but if it is a miss, a miss that small may not throw any.
Note: I posted on the same subject in the Inline 6 forum before I suspected the transfer case.

I don't have a tack, but I would guess it is around 12-1500 rpm's. I will plug the vacume to the EGR tomorrow and take it for a drive.

I plugged the EGR valve and now it seems fine. No buck. I suppose I should throw on a restrictor plate or can I leave it plugged.

Hi Guys
I'm pretty sure the chain has broken in my NP203 , when the first snowfall happened this year I locked the hubs in and had no front wheel grab at all. As I was coming up the road towards the house I heard an expensive sound underneath the truck
.
It sounded like the chain going , anyone know what a shop would charge to replace the chain ? The truck has 70,000 original miles on it and its a 1980 . I do not have the space or the jack to tackle this myself at the present time .
Thanks
XJ
