Re: 04 JGC Quadr-Trac II question
You are correct your Cherokee may have the Vari-Lok option, but not
Traction Control, as I thought.

The Jeep rep explained it to me as 1/8 of a turn of the slipping
wheel. He said that once a year factory guys come to town and do a
'Jeep 101' class for new owners and one of the demo's is to jack one
of the GC's off the ground and let people see it in operation. I have
not been to one of these demo's but maybe someone else has been to one
and can let us know what they saw.
