Any progress on that one? My plan is to ignore until I see a TSB or other good advice.

Thanks!
All I can say is, stay tuned.

I understand that the economics of producing a vehicle may not allow for a lot of these suggestions to be implemented, but your due consideration would be greatly appreciated.

I have talked with a few guys that have re-geared to 4.88 or 5.13 gears. To summarize, the automatic guys tell me they picked up 2 – 3 MPG with 4.88 gears and stock 32” tires. The manual guys tell me MPG is about the same, but drivability is much improved. Automatic guys tell me 4.88 gears are good for up to 33.5” tall tire. Taller than 33.5” really needs the 5.13 gears. Manual guys say they can run up to 35” tires with 4.88 gears, but 37” tires really need the 5.13 gears.

Considering the above, it would be great to have a 4.56 or 4.88 gear offered as a factory option. I don’t think the 5.13 gears would be in the cards for a factory vehicle; too many soccer moms that wouldn’t know what to do with it.


It would be great if the back seat in the Unlimited could be reclined (adjustable seat back) a few more degrees. The upright seat back is uncomfortable for anyone that is not a small kid.

With most of the JK’s competition having 5 speed automatic transmissions ( FJ Cruiser & Xterra ) or a V-8 coming ( H3 ), it would be great to have another engine choice for the JK. Another option that would be good in my opinion would be to offer the new 62TE transmission. The 4.127 first gear would be wonderful for day-to-day drivability.

Lastly, if you guys are going to be in the Indianaplois area, PM me here and I'll take you to one of our micro brew houses. The first round is on me.
The higher gearing allows the engine to operate in the rpm and map range that give higher rates of EGR. Engine noise is probably higher though.

No seat engineers here today but maybe the suggestion will be taken forward.

Hello- The crush cans on the production bumper are part of the the air bag system. Without the crush cans the system operation is affected. As far as I know the only bumper that incorporates the crust cans is the winch bumper form Mopar.

I hope that helps.

Is there added lift on a stock Rubicon over a Sahara or X Model? It appears there may be...can you confirm and how much if any?

Tire Pressure Monitoring, Sunrider Soft Top (on 2-door), and Sirius Sat Radio were made standard. Remote start was added as an option. The rest is pretty much carry over from 2007.

Is there a larger alternator available from the factory?

I assume you have a JK and you would need to upgrade the alternator if you want 60 amps. We do not sell a larger alternator for JK

First off thanks for taking the time to awnser our questions on the forum.

I have a TJ wrangler question: I just changed my axle fluids in my 04 Rubicon. My 2004 FSM says both front and rear D44s require 75w-140. However when changing the fluid I noticed the tag on the rear diff said 75w-140 (as expected) while the tag front diff said 80w-90 (same as D30).

So what weight is right for the front D44, the 75-140 specified by the FSM or the 80w-90 specified by the diff tag?

Each morning when I first put my YJ automatic into gear, the transmission or rearend hesitates; sort of like a cold engine. It feels as if gears are spinning, but not grabbing. It only happens for a few seconds and only when I first put it into drive. After that, everything seems normal. And, it hasn't gotten any worse or better over the year I've had it.

Any clues or suggestions on what to check out. I can tell you the rear diff and transfer both leak.

Thanks agian for the forum.
Without experiencing it myself, I'm going to hazard a guess that you've got engagement delay. This could be as simple as burnt fluid that needs to be changed or your transmission may need a complete overhaul. My suggestion would be to change/flush all the fluid, change the filter and adjust the bands before condemning the unit to a rebuild.

Your vehicle is under warrenty and the dealer should be replacing the original seals.

is there an adjustable Low PSI switch made? or a way to get in contact with the OEM for those low PSI switches? to see if other models are made?

also even when lowering refrigerant levels.. seems the compressor wants to hold 25-30 PSI on suction side regardless of refrigerant temp.. is there any technical docs available on the 2006 wrangler A/C system?

is there pressure balancing going on in the compressor? is it straight orifice tube? is there 1 or 2 orifice tubes? is it variable orifice?

thank you for your help. the reason for all this is that the factory A/C on my 06 wrangler and the late model liberties(it doesnt appear to be just my unit I have test driven several with same results) as well seems to be very lackluster in relation to my previous 3 wranglers.. (a 97,an 00, and an 02)..
-Christopher

OK.. maybe you know more than me !! [ grin ] The systems are pretty much the same on 00 to 06. Some minor changes in the blower moter setup.

It should perform the same ? Kind of hard to guess without seeing/testing it. The system is a fixed orifice tube setup.

There is no stock adjustable switch.. but there might be an aftermarket one? No HEVAC engineer here tonight... I assume you are trying to keep the compressor running longer ??

Thanx!
Bad lighting?

Seriously, the Rubicon has more articulation than any Jeep ever. The front stabilizer bar disconnect system is standard on the Rubicon and is available as an option on the X or as a Mopar accessory.

Yes, we will offer a rear only locker for the 2008 MY vehicle. This will be available in models other than the Rubicon. You will be required to order the front sway bar disconnect with the locker option. All 2008 Wrangler will feature a Dana 44 rear axle.
