ABSOLUTELY NOT!

The tcase has no ability to function as a differential, the fornt and rear
axles are locked together, but the tires easily go at different speeds. The
different speeds means the tcase is being stressed.

When it is suitable to use 4WD, you can shift into it at virtually any
speed. The caveat is that if you are going so fast that the mechanics can't
keep up, you probably don't need 4WD anyway. So, if you are going 45 and see
that 4WD would be useful, AND the road surface meets the demands of the
hardware, then you can shift into 4HI without any trouble.

Shifting into 4HI at any speed is not the same as using 4HI on any surface.
You should only use 4HI on a surface where the stresses can be released
through the tires to the ground.

I am not that far off. I loose track of command track and select track, but
to the extent I hit the proper track, I described the problem pretty well.

Having said that, isn't there a part time mode for the select track, and if
the linkage is maladjusted AND the most recent tcase selection was the part
time mode, then couldn't the tcase fail to shift properly into 2HI, and the
result of such a failure would be exactly what I described?

The Libby only has 5000 miles on it, and the OP says the trouble only
happens intermittantly, and if there was an issue with the linkage, this
could cause an intermittant failure of the tcase to fully disengage.

Command-Trac = 2hi + 4part + N + 4lo.. vehicle is designed for primary use
as 2wd with 4part to be used on loose or slippery surfaces ONLY.. Selec-Trac
= 2hi + 4 part + 4full-hi + N + 4lo.. vehicle designed for 2wd or 4wd
fulltime.. QuadraTrac = 4full-hi + N + 4lo.. vehicle in permanent 4wd..
