The 2-piece cast iron unit will bolt up, but as you noted, you'll have to do a custom job on the rest of the system unless you want all those catalysts...

Yes, please ALWAYS keep the solid front axle on the Wrangler...to me, it wouldn't be a Wrangler without it....

There is a new improved steering stabilizer service fix that should be out by years end that will resolve your issue. Another option is to install a aftermarket stabilizer that is larger than the current production

Well, I already had larger aftermarket (Rancho) stabilizer put on, which kept the steerign in check for about 3-4k, after that the wobble kept creeping back in stronger and stronger to the point when even this stablizier started leaking fluid... I think the problem have to be somewhere else - I cannot change steering stabilizer with every oil change

What can be done to help the zipper on the rear window zip easier? On my JK the teeth get unaligned very easily making it hard to unzip.

Like JeeperDon, I would like some clarification on that point.

Here is what I use, and the advice I give others here on the forum (actually copied from a previous post of mine), it's based on my own research and I would like to know if it's accurate information.

Here's why I use 10W-30 motor oil.

The Mopar gear oil part number used to be 4897622aa, but when you search that part number you'll see it has been superceded by part number 4761839AC which comes up as 10w-30 motor oil. Here's a link to search the Mopar part numbers.

Lubing the zipper helps a lot. I use the same stuff I use for my drysuit - bee's wax.

Mopar does sell a zipper lubricant that helps with this...

This is why I am SO GLAD to be driving an older, computer free Wrangler.

I think the premium that the current crop of diesel vehicles cost over the gas equivalents is pretty reasonable, especially in Canada (Since diesel is back to being noticeably cheaper then gas).

I know that current regs really do a number on your ability to use diesel engines, but hopefully Fiat holds the answer here. At the very least, you know there's an eager and devoted market.

oh yeah, please build a diesel....

Given enough funding you can put any transmission in any vehicle. In the beginning of a new vehicle program , a powertrain is chosen based on many factors ( package space, gear ratios, cost etc.). The calibrators then spend many months programming the computer to meet the vehicle requirements. When a vehicle is in production, the costs to revise a trans are very high so there generally needs to be an engine revision or new model to justify a new trans.

I read on another forum that there was a recall on the center console lock/latch as it can be opened even when locked. Any truth to this? If so, what's the recall/TSB notice number. I checked my VIN for a recall (09 JK built 4/2009, took delivery 2 days before bankruptcy). My center console can be opened when locked when a bit of pressure by hand is applied to the push-in latch. Asked the dealer about it (5/1/2009) and they couldn't repair it, and the remaining JK's on their lot had the same issue at that time.

Thanks,
-Michael
