hmmm... except the only time that I actually switched (using the 4wd
shifter on the floor,directly beside the 2wd shifter) to 4wd, was
'after' I experienced the binding while trying to save my brakes/foot
and using the low gear (bottom setting on the 2wd shifter) to coast
slowly. If I shifted back to neutral, the feeling/noise went away
immediately.... once the road was flat again, everything seemed to be
back to normal again, and I continued driving in my normal "Drive" gear
in 2wd.
I suppose I shouldn't be shifting to low gear like that either huh?
Man, and I 'thought' I knew how to drive! lol

Re: Slipping in 4x4 low
I drove mine in four wheel high on dry pavement for five or ten miles once,
and nothing happened. I think the reason is that I didn't KNOW that I was
in four wheel high. Or maybe since I was on a twisty mountain road all the
turning to and fro kept the drive train unloaded. Or maybe the puny four
cylinder engine is incapable of grenading the drive train. I did notice
some loss in power, and had a dickens of a time figuring out what it was.
I'll bet you all have done this...

Re: Slipping in 4x4 low
Yep, I have done that also. The 4WD light on my TJ's dash is totally blocked
from view by the steering wheel. Still no excuse. I should have remembered
to shift back to 2WD, but I forgot. DUH!!!
