Alright boys I've got a weird one.
My 2002 SE has been an amazing truck for as long as I've owned it and I've never had any issues with the 4WD until now...
When engaging the AWD (shifter push button w/out center diff locked) the truck makes a terrible grinding noise that I can literally feel bringing the truck to a halt if I don't slow down.
Now here's the kicker, if I come to a complete stop and THEN engage the AWD it engages fine and I can drive around completely fine up to speed and stop no problem.
The center diff locks up immediately (4H) and putting the trans in neutral and then placing the t-case into low range (4L) work as they should.
The only time the noise occurs is if I shift "on-the-fly" so to speak, Toyota says you can do this up to 55MPH but I can't do it even below 5MPH.

Could this be something as simple as needing to change gear oil in the t-case?
Both Front and Rear Diffs have fresh fluid. Actually come to think of it I'm waiting for ECGS to finish my new 4.88 3rds (True-Trac and E-Locker) however I don't think that is the issue considering once the truck is in 4WD it drives as it should.
Maybe this is a sensor issue? The grinding doesn't necessarily point that way but the condition it occurs under might...
