hi i'm new here, looking to learn. two days ago i bought a new 2010 liberty sport. a while ago i had a 93 wagoneer but never used the 4wd. i come from a aztec fwd. when the roads here become snow covered, slippery and slushly other drivers tend to drive to slow for me but the aztec did the job for me. i guess i tend to drive on the edge. ( 60-70mph on the snow ) within reason. i have some questions on this command trac ll.

1. on the snow putting it in 4H at 55mph or less will i be able to go 70mph?

i realize on dry roads at a turn - 1 ft wheel turns faster then the other wheel so this isnt good to do. but say i wanted to pull someone out of the ditch and i'm on dry pavement

2. would it hurt to use 4L with the wheels strait going slow?

until i learn more my thinking is in 4H or 4L with 50% torque to both axles and wheels strait this should be ok, but it something i wont try until i get imput from you guys. thanks for your help.

Lets add another note with command trac ll.

How often should you put the Jeep into 4HI or 4LO?

We got the jeep for dirt cheap and never need or use 4WD, but we have it.
The sales person said engage 4WD once every 3000 miles...

We do not live in or close to dirt roads.. all I have access to is dry pavement....

There's so many different theories ranging from "you need to put it in 4hi once a month" to "you never need to".

You can shift into 4 hi on the fly.... so every once in a while when you're driving slow approaching your house, just hit the lever and let it engage. Let things spin for a 1/2 mile or so and turn it off before you pull into your driveway. Do that a few times a year for piece of mind and you're set. $.02

Never run 4hi or 4low on any hard surface,even if wet.Good way to break stuff even if done for a few feet.

boat ramps.. usually due to poor traction surfaces like wet pavement with gravel/sand/gunk on top of it and often the actual parking lot is graveled

and while it is common practice, I've also installed new transfer cases for those with CTrac transfer cases who used it on boat ramps, forgot to take it out of 4hi before leaving the gravel parking lot, hit the pavement on the road/highway etc and split the case or sheared the tail shaft before they got to the highway within a very few miles of the marina.

Ours are all nice and paved.

Towing a boat, thereby adding weight/traction, plus driving on a dry/paved surface and turning... yes, that would result in damage if someone left their vehicle in 4x4 for a few miles driving down the street and probably making some sharp turns to swing that boat around some side streets.

If you put your vehicle in 4x4 and drive in a straight line for short distance @ low speed and break something, it's due to another problem. Like wrong sized tires.

There are situations offroad where your tires will bind of the drivetrain more than the above would. If these transfer cases were that fragile, you guys would be blowing tail shafts on almost every offroad trip.

It would still be best to engage it on dirt/grass/gravel/etc. That goes without saying. But you're not going to blow up the tcase in a few feet of driving in a straight line. Otherwise every soccer mom in my area would have a broken down jeep
