The Jeep Wrangler is a compact and mid-size (Wrangler Unlimited models) four-wheel drive off-road vehicle manufactured by Jeep, currently in its third generation.

The Wrangler is arguably an indirect progression from the World War II Willys MB through the Willys civilian Jeeps (Jeep CJ) of the mid-1940s through 1980s that were produced by Kaiser-Jeep and by American Motors Corporation (AMC). Neither AMC nor Chrysler (after it purchased AMC in 1987) have claimed that the Wrangler was a direct descendant of the original military model.

Background

Outwardly resembling the Jeep CJ-7, the Wrangler, which was formally announced in February 1986 at the 1986 Chicago Auto Show, was based on a new set of design parameters. "The product philosophy behind the two vehicles" François Castaing (AMC VP of Product Engineering) explained, "is completely different". Just like the Willys MB and the Jeep CJ, Wranglers continue to use a separate body and frame, rigid solid axles both front and rear, a fold-flat windshield, and can be driven without doors. But its suspension, drivetrain, and interior were borrowed from the new Cherokee (XJ) model.

The Wrangler debuted in 1986 as a new model after discontinuance of the famous Jeep CJ series. It was revised in 1996, and completely redesigned in 2006. In addition to the model name Wrangler, each model received a designation corresponding to its generation: YJ (1986-1995), TJ (1997-2006), TJU's (commonly known as LJs- 2004-2006 Unlimited models, or YJL, in the Egyptian owners manual.),

  JK (2007-present, with the 4-door 'Unlimited' variant unofficially called a 'JKU' on internet forums). Foreign military versions of the Wrangler have carried the J8 designation which was initially dubbed TJL when first produced at Arab American Vehicle's Egyptian plant.

Jeep YJ models were manufactured between 1986 and 1995 at Brampton Assembly, and subsequently at the Toledo South Assembly plant. A major difference in the 1987-1995 models were the rectangular headlights, which reverted to rounded ones in the TJ and then JK versions. In 2006, Wrangler production was moved to Toledo Complex. Post-2006 Wranglers were set apart from their predecessors by the angle of the grille. In all previous models, the grille was flat and even with the front fenders. The newer Wrangler was constructed with a grille which angled out from the top, and then continued in a straight line from the midway point, toward the bottom. This decreased the hood length, while increasing the length of the fenders. In more recent models, this angle has been lowered more toward the bottom of the grille.

In Egypt, the YJ was produced as well as a long wheel-base version, dubbed LJ (or labeled as YJL in Egypt's Owners Manual), and which has retained the 2-door design. The YJL is considered as the first predecessor of the JK's long wheel-base by continuing as TJL (aka J8) which has directly inspired the JK's 4-door.

There is a Jeep Wrangler Pickup coming into production in 2017.

YJ (1987-1995)

Development of a potential CJ7 replacement was green-lighted in 1982, with engineering and design work (under Chuck Mashigan) commencing. After approval earlier in 1983, a final design freeze occurred by the fall of 1983, with CJ7-based mules being built in late 1983 and the first production body test prototypes in the spring of 1984. By late 1985, development concluded, as the transition from pilot to series production began. In February 1986, the 1987 Jeep Wrangler was unveiled, entering production that March, and going on sale on May 13, 1986.

The Jeep YJ, sold as the Wrangler in the United States, replaced the Jeep CJ in 1986 and was built in Brampton, Ontario, Canada, until the plant closed on April 23, 1992. Production was then moved to Toledo, Ohio, using the same plant that produced the Willys Jeeps during World War II.

American Motors Corporation (AMC) had designed the new Jeep to be more comfortable on-road in an attempt to attract more daily drivers. It was an entirely new design with a wider track, slightly less ground clearance, and more comfort. The YJ still had leaf spring suspension similar to that of the CJ - however the springs were wider, and the YJs sported trackbars and swaybars for improved handling. Despite the new grille, the body is very similar to that of the CJ7, and it is interchangeable with some major modifications. The YJ also was given a larger windshield over the CJ. The YJs are easily identifiable due to the rectangular headlights and the fact that the wiper blades rest on the windshield, giving this version a distinctive look. The blades rested on the windshield due to the now wider arc of the blades to clean the larger windshield. These two changes were later removed when the TJ was launched 1996. 632,231 YJs were built through model year 1995, although YJs were still sold into mid-1996, bringing the total production number to 685,071 units. Despite its similar look to the Jeep (CJ) its design was new from the ground up and had more in common with the newer downsized Cherokee (XJ) model.

The YJ used a 2.5 L AMC 150 I4 or optional 4.2 L AMC 258 I6 until 1991. That year, a fuel-injected 180 hp (134 kW) 4.0 L AMC 242 variant replaced the 112 hp (84 kW) 4.2 L 258 CID straight-6. The NP207 transfer case was used only for 1987 and replaced by the NP231.

The roll cage was extended in 1992 to allow for rear shoulder belts, and anti-lock brakes were added as an option the next year. An automatic transmission option for 4-cylinder Wranglers came in 1994, along with a center high-mounted brake light.

In 1994, the slave cylinder on manual transmissions was moved outside of the transmission's bellhousing to allow for easier replacement, and in 1995 the Dana 30 larger U-joints were used [front axle U-joints (297x) and rear pinion U-joint (1330)]. For the 1992 model year, the YJ switched over to an electronic speedometer, outmoding the cable speedos on older YJs. 1995 was the only model year to have a fully galvanized frame and body.

There were no 1996 model year Jeep Wranglers. YJs produced in early 1996 were sold as 1995 model years, but featured a few new parts not seen on any earlier YJ. This included the new TJ bumpstops on the hood (rubber boots vs the traditional U-bars), reinforced tailgate hinges, and some even had rear TJ bumpers. Some also got the newly tuned I6 that was designed to run quieter in preparation for the TJ.

Top options for YJ were the same as those offered on TJ. A Soft top with "half doors", featuring soft plastic zipper windows came standard (windows could be removed completely from these doors). Full-frame doors with conventional glass windows were optional on soft-top models. Hard tops with rear wiper and defroster were optional, but came standard with full-framed doors. The YJ featured large mirrors with manually adjustable arms on half-door models, while full-framed doors received smaller adjustable mirrors with fixed arms (which were mounted further away from the door corner, compared to the larger-style mirrors). Depending on year and interior color, Jeeps could be had with the top colors in black, white, tan and gray. Roll-bar padding normally matched top color, with the exception of white tops.

From October 1990 until 1994, Jeep produced an options package on the YJ Wrangler listed as the "Renegade Decor Group". Vehicles were shipped as optioned Wranglers to American Specialty Cars (ASC) in the Detroit area, where the Renegade Decor Package was installed, then shipped back to Jeep for delivery to dealers. Renegades all have a small sticker on the driver's side door, right above the latch denoting the visit to ASC. Initially, all Renegades were white, black, or red. Blue and bronze were added for the 1992 and 1993 model years, respectively. The Renegade Decor Group was a $4,266 option over a base Wrangler for 1991 and included special alloy wheels, exclusive body flares, along with many other features.

TJ (1997-2006)

In 1990, development of a successor to the YJ began in Chrysler's "Jeep-Truck Engineering Pre-Program" department under Bob Sheaves and TJ program director, Craig Winn. Mules based on the YJ were built from 1990 to 1993, when formal approval was given for the TJ development program at a $260 million budget. From 1991 to 1992 designers worked at the new Chrysler Technical Center, building on various design proposals. In late 1992, Michael Santoro's TJ proposal was chosen by Tom Gale, Lee Iacocca, and executive management. In May 1993, now with engineering and supplier input, Santoro's final Wrangler production design was frozen at 32 months ahead of initial assembly. Verification prototypes using production bodies were built from early 1994 and tested through late 1995. As YJ production ceased in December 1995, the last pre-production TJ examples were assembled, with start of series of production in January 1996.

Unveiled on January 2, 1996, at the 1996 Detroit Auto Show as an early 1997 model year introduction (1996 model year skipped), the TJ was an evolutionary update. It later arrived in Jeep showrooms in April 1996, after 6 years of overall investment and 36 month production development phase.

This updated Wrangler featured a coil-spring suspension (based on that of the Jeep Grand Cherokee) for better ride and handling, and a return to the classic CJ's round headlamps. The engine is the same 4.0 L AMC 242 Straight-6 used in the Cherokee and Grand Cherokee. A 2.5 L AMC 150 Inline-4 engine was available on entry-level models until 2002 when the 2.4 L DOHC 4-cylinder engine previously used on the Chrysler PT Cruiser replaced it.

A right hand drive version of the TJ was available for export markets, and was also offered for sale to U.S. rural route postal carriers. The version offered to U.S. postal carriers was only available with an automatic transmission.

In 1998 (MY1999), the fuel tank became standard at 19 U.S. gallons (72 L; 16 imp gal) capacity. There were some changes between the 2002 and 2003 years. From 1996 to 2002, the side door mirrors were black metal framed mirrors; and from 2003 to 2006 they were plastic molded mirrors. The fit of hard and soft tops is slightly different, and the fabric and colors available changed from 2001 to 2003. In 2002 (MY2003), the 3-speed automatic transmission was replaced with a 4-speed automatic with overdrive. The overdrive can be turned off with a dash switch. The radio bezels went from a rectangle in 2002 to a rounded-edged rectangle for 2003. The sound bar inside was changed to sound pods. The interior seats also changed design, going from a rounder model to one with a distinct separation between back and headrest areas. The standard skid plate was also revised for 2003 to make room for the Rubicon's bigger NV241OR transfer case. The change from the 30/32RH to the 42RLE also gained an additional skid plate.

This version of the Wrangler is also notable for being the last production vehicle to use AMC-related parts. The AMC Straight-4 engine was retired after the 2006 model year, and both the AMC Straight-6 engine and the door handles (the latter of which first appeared on AMC vehicles in the 1968 model year) were retired along with this generation in 2006. Like the YJ Wrangler, the TJ Wrangler used both the AMC passenger car door handles as well as the larger door handles off the AMC-built Jeep CJ for higher-end models.

JK (2007-present)

Development

In 2001, DaimlerChrysler commissioned development of a TJ successor under the "JK" program code for the third generation Jeep Wrangler. Design work began almost instantly in 2001, with Mark Moushegian winning an internal design competition against Dan Zimmerman (later responsible for 2005 Jeep Hurricane Concept) by the second quarter of 2003. In January 2004, the JK design was frozen at 31 months ahead of production and work began on a conceptual preview.

On November 16, 2004, Jeep released 2 CAD renders of a Jeep pickup. On December 5, 2004, the 2005 Jeep Gladiator Concept was unveiled ahead of its January 2005 Detroit Auto Show debut, previewing many of the design elements on the incoming JK. The Wrangler JK was introduced at the 2006 North American International Auto Show with past Chrysler group CEO Tom LaSorda driving one up some steps and through a plate glass window, just as Robert Lutz had done at the show in January 1992 with the Grand Cherokee.

Initial release

The 2007 model year brought a complete redesign of the Jeep Wrangler, and also a four-door model. The TJ chassis was replaced by an all new JK platform. This next-generation Wrangler was noticeably wider than the previous model, with a 3.4-inch (86 mm) wider track; and though the two-door model has a 2-inch (51 mm) longer wheelbase, it is actually 2.5 inches (64 mm) shorter in overall length than the TJ, allowing for a 44.3° approach angle and a 40.4° departure angle. With a larger factory available tire size of 32 inches, the breakover angle on the Rubicon is increased from 22.6° to 25.4°.
The four-door Unlimited model has an over 20-inch (510 mm) longer wheelbase at 116 in (2,950 mm) to offer much improved rear seating room, but is nevertheless only 2.4-inch (61 mm) longer than the 2006 TJ Unlimited.

The JK was first available for purchase with the 2007 model year, beginning in August 2006.

The JK Wrangler has been offered from the start in two models:

• A short-wheelbase 2-door, in X, Sahara and Rubicon trim levels.
• A long-wheelbase Unlimited 4-door, also in X, Sahara and Rubicon trim levels.

The Wrangler X is available with factory installed right-hand drive, targeted at U.S. Mail carriers. Rural mail boxes in the United States are serviced with the carrier behind the wheel. This may also be useful for carriers who wish to get out of their vehicle without the risk of getting hit by traffic. For the 2007 and 2008 model years, the right-hand drive Jeep was the short-wheelbase Wrangler. For the 2009 model year, the right-hand drive Wrangler will be replaced by the right-hand drive Wrangler Unlimited.

Stability control is a new safety feature for the JK Wrangler. All versions offer off-road tuned Anti-lock braking system and traction control system with electronic limited slip differential. Standard on the Rubicon trim is a new electronic sway bar disconnect system.

The JK runs almost all vehicle functions, other than steering, under computer software control. Engine, transmission, and to some extent braking are computer controlled, as are lights and auxiliary systems. This is a first for the Wrangler. As of mid-2007, there have been three safety recalls for software fixes.

A Sunrider convertible soft top is standard equipment. Also available on the JK model is an optional 3-piece modular hardtop. Although the doors can still be removed in traditional Wrangler fashion, power windows and remote power door locks will be offered for the first time in a Wrangler. Another first is an available navigation system. This is the first generation of the Jeep Wrangler to have a change in the tail lamps.

JK Wrangler Unlimited

The JK series 2007 Wrangler Unlimited was unveiled at the New York Auto Show on April 12, 2006. It is stretched even more than the TJ model, and featured four doors. This change made it the last-remaining 2-door SUV in North America to gain a four-door option and made it the only four door convertible in production. A full 20.6 inches (523 mm) was added to the JK Wrangler's 95.4-inch (2423 mm) wheelbase. It hit production line in August 2006 and was priced near $21,000.

The Unlimited has the same engine and transmission choices as a short-wheelbase JK. X and Sahara trims offer an option of 4x2 rear-wheel drive in the USA. Optional 4x2 was discontinued after the 2010 model year for the Unlimited. 4-wheel drive became standard for the 2011 model year. It is the only four-door convertible available in the US, since the Hummer H1 with optional rag-top is no longer sold.

The Unlimited offers more options and equipment than any previous Wrangler model, including standard electronic stability program and optional seat-mounted side airbags, remote keyless entry, navigation system, and Sirius Satellite Radio. The navigation and satellite systems are a part of the MyGig Entertainment system that also has a hard drive allowing for the storage of MP3 music files and pictures.

J8 (2007-)

On September 13, 2007, at the Defence Systems and Equipment International trade show, Chrysler LLC unveiled a Wrangler Unlimited version designed for military use dubbed the J8. The unarmored Jeep J8 is equipped with larger brakes, axles and suspension components than the civilian version and has a payload capacity of 1,339 kg (2,952 lb). The J8 also differs from the civilian model by utilizing heavy-duty rear leaf springs for carrying heavier payloads. The Jeep J8 is powered by a VM 2.8-liter (169 CID) four-cylinder turbo-diesel engine that produces 118 kW (158 hp) and 400 N·m (295 lbf·ft) of torque, providing towing capability of up to 3,500 kg (7,700 lb). The engine is mated to a five-speed automatic transmission. The J8 also features a unique air-intake system with special filtration and a hood-mounted snorkel that enables the J8 to wade in water up to 762 mm (30 in) deep and tackle sandstorm conditions for up to five hours. Available as a two-door with an extended pickup bed for personnel or equipment transport, or a four-door multipurpose vehicle, it may be produced with numerous vehicle-body and seating configurations in either right-hand- or left-hand-drive. Targeted for use by the militaries in overseas markets, the J8 is not available in the United States because it will not meet U.S. emissions requirements. The J8 will be produced in Egypt.

JK trim levels

The Standard Wranglers are available in six trim packages (including 2 special editions). The Unlimited Wranglers are available in four trim packages (including 1 special edition). Most packages can be ordered with either hard or soft top, full or half doors ("Sport" and "Rubicon" only).

The Sport base model is available in 2-door versions.
