And, yes, there is a noise. I hear it too. There is also a noise when you step on the brake each time...kind of a little whoosh noise. Everything is electric in the FJ so there are some different noises to be heard.
I think I got the noise. It sounds more like a solinoid click to me than a 'hiss'...
As far as the manual goes for my M6 I can put it in 4H at any time and any speed. From what I can tell, all 4H does is lock the transfer case and cancel VCS/TCS. On black top all the tires should be rolling at the same speed so I don't see how this could cause a problem. The thing I would avoid is shifting into 4H when one of the tires is spinning. I know the auto is a little different. People correct me if I am wrong.
With the Automatic transmission you dont want to be in 4WD on dry black top. Basically the main reason is that your are in 4wd and when making turns, lets say you are making a left turn. The right front tire has a further turn radius than the left front tire. IN 4wd on dry pavement the left front tire needs to slip so the right front tire can make the larger turn. on dry pavement the left front tire cannot slip as easily as it would on wet or off-road surfaces and you get binding and a completely different feel at the steering wheel. Hope this makes sense to you!

But the diffs aren't locked, so turning shouldn't be a problem. The problem would be if the fronts are trying to move at a different speed than the rears. I don't know why they say not to do this either.

True but even with my old YJ which didn't have lockers in 4wd on a part-time 4wd system dry pavement still needs to slip. I could be wrong about the FJ but it seems logical as in the non locked jeeps. NOw if I understand this correctly the MT is a full-time 4wd for dry pavement until you lock the but has the ability to lock lock the transfer case when off roading. Of course with locked differentials the problem becomes even more maginified.
Thanks for the input guys. It makes sense, but just seems sort of odd. For instance when it snows here, there are terrains that are snow covered, icy, and bone dry all at the same time. I guess I should be selective when I use it.
