2007 Jeep Wrangler (Rubicon)

Love the new Rubi

I was fortunate enough to see a "tester" at the Morrison exit, just west of Denver. We were filling up at the same time. I talked to them for a minute or two, but didn't want to corner them.

The front end looks better in a darker color, in my opinion. This Jeep was black. He said the on road handling was night and day, and the wind noise has been drastically reduced. I can't wait to drive one!

Sadly, before the new Grand Cherokee came out, the Jeep Wrangler had the best IIHS crash testing scores of any Jeep!! And i believe that it also had the best reliability scores of any Jeep because it did not have much electronics to break.

An uncle went through 6 or 7 GCs, 3 year leases from work. Two were just about DOA due to electrical problems. Only one did not have any serious problems. But they were the coolest things back when auto-off headlights were new, a voice replaced warning chimes and lights, and a digital washer fluid level reading was luxury.
:D

Why not get both? :D

Bought the 4Runner in April and the Rubi on Saturday.

Nice! Your a lucky man. Maybe my wife will let me trade our Altima in for a Rubi, hmmm... :naughty:
 
My wife and I are going to look at them when they come out. We figure we don't need two nice SUVs, my 4Runner and her Lexus, so we may get one as a fun toy for off-road.

According to Jeep, the new '07 Rubi will be the best off-roader in the world.

Wow, that's a big claim....
 
The Rubicon is definitely a cool vehicle, the only problem is, it is still a HEEP!

I love the top on the Rubicon, that's so much nicer than having a hard top and a soft top...probably great sound insulation, too.

Now if Jeep would only work on their reliability, then they might have me sold...
 
Well, my brother's Town & Country minivan blew it's transmission a few weeks ago...$3000 to repair it! This is a minivan which he cares about a lot...maintain beyond owner's manual recommendations. He does not drive fast. However, he does idle for the kids.

The reason i bring this up is because the new Rubicon Auto will have the exact same powertrain as the Town & Country...4-speed auto with 3.8L V6. The engine is fine (from what i have heard); however, the tranny is a POS!

So, if you were to get a Rubicon, then i would recommend the 6-speed manual model. The manual tranny is quite reliable from what i hear.
 
We had a Rubicon when it first came out and I loved it. Of course we had to thorw a 3" Teraflex lift on it and 33X12.50 Goodyear Wranglet MTR, Warn rockcrawler bumper, and winch, but then it rocked.

This new Rubicon is the ugliest Jeep I have ever seen. Way too much plastic on the outside and the interior is horrible. Why Jeep would make an awesome 4x4 machine like the Rubicon and then put all that crap on it is beyond me.
 
Jeep Plant Hit By Supplier Shutdown
Chrysler hopes for no delay in launch of new Jeep Wrangler.
by Paul A. Eisenstein (2006-02-06)

The unexpected shutdown of Haden Prism LLC threatens to disrupt the launch of the next-generation Jeep Wrangler at Chrysler Corp.'s new assembly plant in Toledo, though Chrysler lawyers were working overtime to keep things on track at the groundbreaking new operation.

The Auburn Hills, Mich.-based Haden is one of three key suppliers central to the operation of Chrysler's new assembly line. Instead of owning and operating the plant on its own, the automaker partnered with the suppliers, who collectively invested a sizable share of the project's total cost, and will each operate a specific portion of the facility.

Kuka Group is currently finishing work on the body shop, Hyundai Mobis will assemble the Wrangler chassis line, while Haden was supposed to be setting up the paint shop. All three suppliers were supposed to be ready to go when the first "S1" pilot vehicles were to roll down the assembly line on February 27.

When Haden's 60 employees reported for work on Friday, however, they were told to go home. The 200,000 square-foot paint facility was being padlocked by the local sheriff due to Haden's Chapter 7 bankruptcy filing.

More than two-dozen U.S. auto suppliers are currently in default, having filed under the more lenient Chapter 11 of the bankruptcy code. That permits them to continue operating while they attempt to sort out their finances. But under Chapter 7, a company has declared itself insolvent and unable to continue operating. In the case of Haden, creditors moved in quickly to protect potential assets.

Without the paint shop, the new assembly plant would be unable to operate. But Chrysler spokesman Jason Vines asserted that "the impact (of Haden's bankruptcy) is basically zero," and that the automaker will move to assume control of Haden's operation as quickly as possible.

Another company source noted that under its contract with the three suppliers, Chrysler reserved the right to take over any of the operations in the event of an emergency such as this. But it is likely to take some legal wrangling before the paint shop reopens, and it is unclear whether Chrysler might have to delay the launch of production. Typically, there is padding in the pilot schedule, so assuming things are resolved quickly, the actual public debut of the 2007 Wrangler could go off as planned.

Toledo at close range

But there's little question, several sources agreed, that Chrysler will have to take a close look at the Toledo project, especially if it hopes to copy the approach with other new facilities in the future. It's not that company officials didn't know of the potential risks going into the joint venture. The challenge, said Chrysler CEO Tom LaSorda, who spearheaded the effort, is "finding comfort in a state of perpetual transformation."

But LaSorda insisted that the risk was more than worth the reward, since the unique approach to the Toledo plant promised to reduce Chrysler's up-front investment, as well as long-term costs, since it reduces the number of workers on the automaker's own payroll.

The entire Wrangler project is expected to cost Chrysler, a subsidiary of DaimlerChrysler AG, about $2.1 billion. That includes development of the new SUV, which will account for more than half of the total figure. The three partners will ante up about $300 million towards the cost of the Toledo plant itself, Chrysler reported in August 2004, when the project was announced.

The strategy is more aggressive than that taken by other automakers, including Ford Motor Co. and Nissan. Ford has set up a supplier park adjacent to its rebuilt Chicago assembly line, where parts makers produce goods, such as seats, as they are needed on the line. Suppliers actually operate within the confines of Nissan's assembly plant in Canton, Miss.

While Chrysler is likely to step in and take over Haden's portion of the new Jeep plant, the automaker intends to stick with its original plan. It is reportedly already in discussions with the German supplier, Durr Industries. Durr was originally one of the lead bidders for the Toledo project, but lost to Haden. Among the major investors in the now-bankrupt firm was Dennis Pawley, one-time head of manufacturing at Chrysler.

"After a long wait, 2007 Jeep Wrangler Chief Engineer Jim Issner has responded to your questions....

1. Can you elaborate on some of the technical changes being made in the 2007 Wrangler? For example, what changes are being made to the drive train and running gear to improve handling and off-road capabilities? What improvements are being made in the 4-wheel drive system to surpass the capabilities of the TJ?

The T case is stiffer and the main case joint is clamped by 18 fasteners instead of 9 previously. The t case consists of three pieces instead of five to reduce the potential for leakage. The largest improvement in capability over the TJ is in the new ETC (electronic throttle control). With the new electrical architecture, the powertrain module knows when the vehicle is in low range and we have developed a unique low range calibration for crawling. In addition, with ESP standard, all vehicles will have BLD (Brake limited differential) which can detect wheel slip and transfer torque to the other wheel with traction. This will provide an increase in capability for vehicles with open differentials.

2. We received a ton of questions about the Wrangler engine choices. With the 2007, we know the power plant will be different compared to the existing TJ. How was it decided to use the 3.8L V-6 as the main engine? What improvements are being made to the V-6 to accommodate the Wrangler? With the current gasoline issues in the U.S., do you anticipate an alternate power plant like a diesel engine or something else being offered in the future?

The new 3.8-liter V-6 engine is more efficient, provides a better torque curve and is quieter than the 4.0-liter I-6 engine. Overall, the 3.8-liter engine provides a better driving experience both on- and off-road. The 3.8-liter V-6 engine is basically the same (application on other products) but has been adapted to the Wrangler for a "north-south" application. This included a new front cover, accessory drive, exhaust manifold and oil filter location change. The oil capacity was also increased to 6 quarts to meet Jeep requirements for engine lubrication.

3. The Bumpers: What is 'blow molding'? Are the bumpers plastic to the ends or is there a solid core that extends out under that plastic? Also, how easy will it be to get a winch onto these new bumpers? How easy will it be to attach aftermarket bumpers?

Blow molding is a process where air is injected into a molten plastic to "blow it" into it's final shape. The bumpers are plastic to the ends and the bumpers are easily unbolted from the body. The stock bumpers will not support the addition of a winch but Mopar will offer one that does and is designed specifically for the new Wrangler.

4. Why did Jeep stick with a part-time 4-wheel drive system instead of a lockable/openable center differential configuration (full-time system)?

Customer feedback over the years has shown that our customers prefer a selectable system."
 
Part II

5. What height can the new Wrangler be lifted without having to change the driveshafts or swapping the cv-joints for u-joints?

We don't know since we do not produce or test lifted vehicles.

6. I didn't want to paraphrase this next question, it comes from one of our readers with the nickname, 'disturbed': "The number 1 question I have is WHY OH WHY DID YOU GUYS STICK A D35 UNDER THIS THING? This is THE most hated Jeep/Dana axle assembly ever produced and to continue to use it under the entirely new JK platform (even with upgrades) is mind-boggling. The D44 or AAM equivalent should have been used across the board for all JKs."

The Dana 30 front axles have a high pinion design (TJ was a low pinion design) to provide greater gear strength, the housing is stiffer and stronger, and the pinion bearings are larger for improved durability.The Dana 35 rear axle also has a larger pinion and unitized wheel bearings. The prior design had an on-shaft bearing. The axle shafts have also increased in cross section for improved strength. Overall, the axles have been improved over its predecessor. In fact, we are considering different names for the axles since they are virtually all new.

7. Why was the decision made to discontinue the 'Jeep' stamp (or as many people now call it, the 'Joop' stamp) in the body tub? That's been a signature part of the Jeep Universal design since the first CJ5's.

This was a styling decision. The chrome Jeep badge was added to the front grill to fall in line with our other Jeep products.

8. Do you see the JK-platform spawning any other Jeep vehicles aside from the two-door and four-door Wrangler variants. Namely are there plans for a pickup variant?

Not at this time. Unfortunately, we are not able to discuss future products.
