Hello all,
First of all, this is on a 97 xj, 4.0, Automatic, all stock, no lift etc. NP231 transfer case (Pretty sure, no full time 4wd)
Anyway, when I am driving in 2wd, I don't get the noise, but when I am in 4wd when I get around 25-30 mph it starts making a whirring/howling noise that sounds like it is coming from the front end, possibly front passenger side, but it could be transmission/transfer case area I suppose. It is kind of a difficult noise to describe, it isn't screechy like brakes, and it isn't rhythmic like a wheel bearing. It is a real steady, somewhat high pitch, almost like a tea kettle whistling, but not real loud. It is quite noticeable with the radio off, but with it about half volume you can't really hear it.
It only happens in 4wd, if I shift to 2wd, it stops immediately, and it only happens when I am on the gas. If I let off it goes away pretty much immediately as well.
Where do I even start looking? also, should it be alright to drive in 2wd for the time being as it doesn't make the noise then? I have only been putting it in 4wd when absolutely necessary and then switching out when traction improves.
