2008 4.7L Question

Hopefully this isn't a "future product" question - why did the new-for-2008 4.7L engine not have MDS?

I wish the UC package included a solid front axle in place of the IFS. Not that it is that evil, but someone that buys the Up Country package would understand that the trade-off is a vehicle that is more off-road oriented than street. Then guys like me can buy a CRD WK in UC trim and have a vehicle that meets my preferences.

Any large reason why the uniframe can't be adapted for both scenarios?

I think alll of us feel this way..

Axle strength

Can you compare the strength of the front and rear axles to say the D44s in the JK Rubicon? Any thoughts on what spares to carry for the front axle?

I agree cepcnc, I've owned lifted vehicles for 10 yrs and have avoided accidents in every situation so far(knock on wood). To me it's not the vehicle but how the person drives it within it's capabilities in emergency situations. Not over turning the wheel for example.

Do the clutches in the ELSDs require any maintenance after extensive use? The reason I ask is my '05 "bucked" a far amount in low range with making tight turns offroad. At 35,000 miles it no longer does this and I wonder if the ELSDs are still engaged properly?

We evaluate whether or not to add MDS based on the compexity of the powertrain and the benefit it would add in the application. As an example, we don't offer MDS on the Ram 2500/3500.

The new 2008 4.7L offers better fuel economy vs. the previous design. We will of course consider your suggestions - thanks!

hehe, I did it but they can't help me either...seems they don't have yet final answer. However someone told me few minutes ago, dealerConnect offers a new PCM/TCM Falsh for stall/die engine issues that fix it. Hope it works. I'm going to check that.

Thanks,

Jeep engineers are constantly reviewing warranty and field data, to understand vehicle performance, how our customers use them, and improve them.

Thanks for participating tonight.

Why was the decision made to use IFS instead of a solid front axle? I heard rumors of Jeep testing an IFS/IRS GC before the WK was released, but they couldn't make it handle as well as a GC on solid axles. Is this true? Are there any chances of a return to solid front axles or is car-like ride more important than off road ability to too many people?

SFA in other countries?

In the past Jeep has installed stronger front axles to accomodate local conditions (i.e. Venezuela ZJs had D44 front axles). Did Jeep ever produce a WK with a solid front axle? Any thoughts on level of difficulty of replacing the WK's IFS frontend with a JK D44?

Well I am going to see you in Virginia for my 10th Camp Jeep and will try to catch an engineering roundtable. Thanks for taking the time tonight.

Last question.

If the WK and JK got into a fight, who would win?

Is there a specific mileage range when one would consider a 5.7 fully broken in? Do synthetics effect (extend) break-in. Is there a mileage point for the drive train? I remember the first 100 miles on my '07 Overland the drive train seemed very stiff.
