Question: Tire Pressure Monitoring... at least on my '04 KJ, how often does it recheck the tire pressure in each wheel? I can't figure it out, as I use it when airing up the tires?

[mighty4banger]

2 questions in one... For each KJ & 08's (KK right?) are there different ESP programming for manuals vs. automatics?

My old man has a few questions:
Why the heck (I am making is nicer than he did) are tine window controls in the center console still (is this still the case in 08)?

Also, when he had a Grand Cherokee, the wipers would turn on the headlights automatically. WHy does his newer vehicle not do so? In IL, it is law to have the lights on w/the wipers.

He told me his new Liberty is fully loaded, so if a feature is hidden, please let me know.

Thanks.

Well, new 2008 Liberty has window controls on the driver door.

Yes, "headlamps on with wipers" feature can be turned on by the dealer !!

I'm sure your parents are enjoying their new Jeep

Our official position on tires is that we can only recommend replacement units of same size and construction. Since you have already invested in a larger tire, you should look for contact areas in the wheel liner. Chalking the tire and duplicating the maneuver could help. You might check the inside front corner of the left front wheel house based on your comment. Occasional light contact during a low speed maneuver (parking) to a plastic liner may not be a problem if that's all it is. You can check to assure that the liner is properly secured in that area. If you can pinpoint the area, check to see what's behind the plastic liner. If the liner is covering a flange or sharp edge, you may want to take some action to relieve the potential contact.

Thanks! That is a fair and "legal" answer. The front driver's tire only rubs on sharp turns from parking. The tire otherwise looks fine (no damage). Plus the KJ simply looks much better with slightly larger AT tires (REVOS).

What was the influence behind the new exterior/interior styling, besides the Commander? I'll add that I think the new design is a vast improvement over the last Liberty, btw

BTW

As opposed to a specific vehicle, the '08 Liberty design incorporates a lot of cues from many of our classic Jeeps. Things like the 7 slot grille, trapeziodal wheel flares, more upright stance and command of the road seating position

Glad you like the new look!

Yes, they are indeed different. Manuals may have stalling concerns with higher brake pressure applications and are tuned to help minimize this. There is also some ABS/ESP prompted interation with the automatic transmission that the manual can't facilitate. Thanks for writing!

I am just wondering why all the jeeps are looking the same now, except for the Wrangler. Why is there not more being done to separate the exterior designs and have them distinctive instead of just clones to each other?

My husband and I purchased a Grand Cherokee last summer, which was supposed to be for him. I fell in love with it and (luckily) wound up with the GC as my primary vehicle.

It's time for us to replace my husband's current vehicle. Since we both love the GC so much, we decided to look at Jeeps again. My last vehicle was a Chrysler Sebring Convertible. So when I saw the new 08 Liberty, I thought what a great vehicle for me!! We live up on a mountain now and 4x4 is a must for both of us.

We took a Sport with a SkySlider out for a test drive over the weekend. (We had to drive several towns away to find one with a SkySlide.) Within 5 minutes, I knew I found the vehicle for me. I just ordered a Modern Blue Pearl Limited yesterday with the SkySlide. I am hoping to get it by year's end so I can show it off over the holidays. (There was not a Limited within a 250 mile radius that was fully loaded with the SkySlide, so we had to factory order.)

I took an 07 Liberty last year and thought it was okay, but didn't think it was suitable for us. Kudos to Jeep. I love the redesign. The SkySlide was a huge selling point for me. (My husband is happy knowing now we'll both have Jeeps and he gets his GC back!)

As someone who has always wanted a Wrangler --- but with kids, it's never been practical, the new Liberty really fits my needs and my wants in a vehicle. Thank you for filling the void for those of us who want a sporty 4x4 that opens up to the sky that other vehicles such as a convertible or a Wrangler just doesn't fit.

Well thought of one last thing. You guys dont have to do this if you wouldn't like but i figured i would ask since you are here.

Im in the process of making a KK website that is linked off of JF (it is apart of JF). I was wondering if you guys could give me a paragraph summing up the 08 KK for me to use in my KK article, it will be quoted appropriately.

Basically if you guys had to sum up the KK in a single paragraph what would it say?

One mans clone is another's family appearance. Jeeps have had a variety of looks over the 65 plus years, but the one consistent design cue is that you knew a jeep the moment you laid eyes on it. Design themes ebb and flow.

Thanks for the kind words - that was one of the goals with the skyslider: to give people for whom the Wrangler was impractical a similar "open air" experience!

Trac-Lok's essentially have two functional abilities; a pre-load (transfers a small amount of torque with a wheel in the air), and torque bias (multiplies torque across the differential). The pre-load is essentially controlled by spring force which does reduce with wear in the differential. The torque bias tends to last much longer. The most effective way to utilize the Trac-Lok differential regardless of remaining pre-load is by modulating the parking brake to generate resistance at both wheels. This allows the torque bias to multiply that resistance across the differential.

Below is the test procedure:

DIFFERENTIAL TEST
The differential can be tested without removing the
differential case by measuring rotating torque. Make
sure brakes are not dragging during this measurement.
(1) Place blocks in front and rear of both front
wheels.
(2) Raise one rear wheel until it is completely off
the ground.
(3) Engine off, transmission in neutral, and parking
brake off.
(4) Remove wheel.
(5) Use torque wrench to rotate
wheel and read rotating torque.
(6) If rotating torque is less than 41 N·m (56 ft.
lbs.) or more than 271 N·m (200 ft. lbs.) on either
wheel the unit should be serviced.

Although I cannot disclose corporate spec that is used for Tire Pressusre monitoring sensor transmission , I can tell you that sensors trasmit whenever change in pressure is detected in any of the tires. Also, sensors transmit while the vehicle is in motion with a speed above 15 mph for at least 8-10 minutes.

Hope this helps you understand TPM feature better

I am curious as to why the new Liberty did not get the 4.0L V6 as an optional engine.

[mighty4banger]

I was told (I have a YJ) that the KJ ball joints were different than the "normal" ball joint...(opposite of the YJ) How are the KK's designed? (same or opposite?)
