Re: 04 JGC Quadr-Trac II question
Hi Dan,
The trademark name is "Traction Control", and the car must first
have ABS. Jeep, and most luxury cars have been using it for years, some
even use the automatic brakes for high speed steering. The Grand
Cherokee has been using it instead of limited slip differentials since
'97, of course it's an option. It at least eludes to the fact that
brakes are used in this Chrysler rhetoric:

Re: 04 JGC Quadr-Trac II question
Sorry, but the previous post is wrong - the brake is never applied on the
QTII.
The link that L.W. provided does a great job of explaining how the system
works - it's 100% mechanical, essentially combining the concepts of how an
oil pump works and how a clutch slave cylinder works.
As to your question, I would agree with the 1/2 second statement.
Bottom line, it's an awesome 4WD system.
About two years ago, I was launching my SeaDoo off of a boat ramp with my
2WD Dodge Truck. The water level of the lake was low so I had to back far
down the ramp to launch the SeaDoo.
When I retrieved my SeaDoo I backed the Dodge past the end of the concrete
boat ramp onto the soft gravel. It was almost buried to the axle before I
gave up.
I drove my '99 GC down the launch and pulled forward until the two vehicles
were almost "nose to nose."
I then secured a 10,000 pound tow strap to the frame of the Dodge and wound
the strap through the front tow hooks on the GC.
When I started to back the Jeep up the ramp, I could feel the rear tires
bite the concrete ramp for traction. After only minimal wheel slip I could
feel the front suspension compress as the front wheels clawed for traction.
Before the Dodge "popped" out of the hole that I dug, the Jeep managed to
use each of the four wheels to claw for traction on dry concrete - at one
point, all four wheels were turning at the same time.
Sorry for the long post, but I didn't want you to mis-understand how the
system works. If you are still unclear, I would recommend the link in
L.W.'s original post.
As a side note, the Mercedes 4WD system on the ML SUV works exactly as L.W.
describes.
Have a great week and enjoy your new Jeep.
