Its fall. and 100s of posts every year on this, and nobody can read the manual.
nor can i guess if you bought Command Trac or select track
nor if driving on ICE or dirt.
you have command track, and must never be driving on ice free pavement, same as ww2 jeep that or CJs

this is called wind up, read the operators guide,
it tells you never to do that... in the guide,
there is no center differential in your car. zero.
so one tire must be on ice or dirt (sand/grass, gravel or ice)
see why

if you ignore this damage can happen see some now.
posted 100 times this.
you bought the wrong jeep, it seems. to me.....


called WINDED up. and puts huge forces on that poor chain,

stop and RTM.
as you turn the car, the tires roll at different speeds, so do the front and rear axles.
this force is huge.
and the driveline can not handle that.
on the SELECT trac, (not 4Low) there is a clutch
that slips or a real center differential.
but not on your car.

the first symptoms are bucking and jerking in turns
and noise (all bad) and gear lever sticks.
when fully wound up the gear dogs JAM hard.
i have a jeep TSB
that states
ok you wound it up.
jack up one tire. and shift back to 2H.
(yes, the least damaging way to correct this)
and damage on gear boxes is accumulative.


the false illusion is driving straight, in 4H
and its seems ok, (sure all 4 tires turning same speed sure...)
but not in turns.
but you tell me how you can drive all day going
straight. and what is the point of that>??>

google how to use part time 4wheel drive.
learn how it works and how not.
