2011 Grand Cherokee (WK2) Limited Slip Option

The specs on the 2011 Grand Cherokee indicate that only the rear axle has a limited slip option. I currently own a 2005 WK with Quadra Drive II which has limited slip in the front and rear axles. Why would Jeep degrade the drive train such that the WK has more off road capability than the WK2?

Re: 2011 Grand Cherokee (WK2) Limited Slip Option

If it turns out to be true and not a simple misprint, my bet it that its because the WKII uses the same diffs as the Merc ML......

I am not an offroad guy...so explain to me the big deal about no limited slip on the front

Well, if you DO happen to use it off road, the more traction the better.

Re: 2011 Grand Cherokee (WK2) Limited Slip Option

maybe Milous will have more info as to why they did not include the ELSD.

Re: 2011 Grand Cherokee (WK2) Limited Slip Option

I've been trying to get more information on the '11 drive systems but haven't found anything too detailed yet. Manuals and brochures are in their early stages of developement and there is not much other information to go on. Engineering documents I've seen clearly list only the rear as having a LS axle.

I'm sure that there is someone out there with far more off-road expertise in this area than what I can offer. However, from what I have seen over the years are endless comments and assumptions about how "capable" (or "uncapable") the Grand Cherokee is/might be in its different generations. And this always happens before a new gen is released and before anyone has taken one off-road for testing.

When the WK came out a lot of people panicked because it was switching to IFS. They thought it would "suck" off-road - which was really not the case. Long before the WK was launched I had information about the upcoming IFS change and posted it on my site. Not long afterwards I received a call from someone at Jeep, an exec that I had met at one of the national shows. He asked me if I would remove any reference to "IFS" as it was "sensitive" information, that they prefer word to get out closer to launch when reviews were to be released. I complied and "IFS" disappeared from anywhere I had mentioned it.

In order for the new WK to be successful Jeep had to go with what the majority of GC buyers and the market wants - and that is a premium on-road ride along with premium amenities. While the new WK may not be for hard-core off-roaders, they are in the very small minority. At least Jeep has not left the off-road market behind, the new WK will have respectable off-road capabilities. And of course they still build Wranglers, which is where Jeep's off-road focus is really at, some great changes and improvements are coming in the 2011 and 2012 Wrangler models.

I haven't done much off-roading in my own prior Jeep vehicles (WJ's), just never had the time. But if I were to ever get into it in a serious way, the solution would be simple - I'd buy a cheap used ZJ/WJ or Wrangler and take it to the hills and beat the crap out of it. I would never want to take a brand new $40-$50k vehicle and drive it in deep mud and rocks etc.

I'm not referring to anyone on this board, I haven't been here that long, but it seems that the people that complain/have complained the loudest about GC "capability" (WK1 and WK2) are those that have or had no plans to buy one, and if they did buy one would never even utilize the off-road capabilties, whatever level they come in at, to their fullest extent.

Finally, how does one define "capable" when it comes to "off-road"? Ask a thousand Jeeper's and you'll get a thousand different answers. It means something different to everyone. I am one who is glad that Jeep has offered "something for everyone". Every model has to have some sort of compromises to satisfy all of the different buyers out there, and from a marketing and engineering standpoint there also has to be compromises, one model of Jeep cannot be built to do everthing that everyone would want it to.

Thanks for the detailed reply Milous!
I'm personally not bothered by the switch to independaent suspension all round, nor was I worried about it for the front of the WK, as I see it as a benefit rather than a hindrence, as you're right in saying the WK is not the first vehicle anyone should chose for really serion off roading.
The benefits in NVH and driveability/handling far outweight any negatives for 99% of GC owners.
However, for some of us that DO use them for light duty off roading, the benefits of locking diffs are clear, especially with independent suspension as it typically offers less wheel travel. With locking diffs, it doesn't matter so much if one wheel at each end isn't on the ground, as the lockers will ensure it keeps moving.
This is why I personally value the front a rear lockers that my Limited has, it gets me places on sand where most 4WD's with silly big wheels won't.

You have both rear tires in mud with no traction and one front tire off the ground... Damn too bad you don't have that locker in the front to get the tire that is on the ground to pull.
