Jeep Cherokee (Liberty) 2002-2012 Haynes Service Repair Manual

The Jeep Liberty (KJ), or Jeep Cherokee (KJ) outside North America, was introduced in 2002 to replace its predecessor the Jeep Cherokee (XJ). The Cherokee comes with Jeep's distinctive 7-slot grille and round headlights. On April 12, 2002, the Cherokee was lowered one inch. In 2003, the rear drum brakes were replaced with disc brakes. In mid-2003, the automatic transmission was changed from the 45RFE to the 42RLE. In 2005, Jeep redesigned the front end and added a diesel model (available for export outside the US since 2002). In 2004, a passenger chair airbag sensor had been added. In 2006, VLP and ESP were added and ABS became standard. The Cherokee has come in four trim levels: Latitude, Sport, Renegade, and Limited and two unique models: CRD and Rocky Mountain Edition. The Latitude, Sport, and Limited are the only versions still in production.

The Jeep Cherokee (KJ), or Jeep Cherokee (KJ) outside North America, was a compact SUV created by the Jeep marque of Chrysler. Introduced for the 2002 model year as a replacement for the Cherokee (XJ), the Cherokee was priced between the Wrangler and Grand Cherokee. It had been the smallest of the 4-door Jeep SUVs up until the car based 4-door Compass and Patriot arrived for 2007. The Cherokee showcased unibody-construction. It was assembled at the Toledo North Assembly Plant in the United States, as well as in other countries including Egypt and Venezuela.

Inspired by styling from the Jeepster and Dakar concept vehicles, the Cherokee was intended as a replacement for the discontinued Jeep Cherokee. The Cherokee also marked a few firsts for Jeep. It was the very first Jeep vehicle to use rack and pinion steering. It also the first Jeep to use the two then-new PowerTech machines; the 150 horsepower (110 kW) 2.4 L straight-4, which had been discontinued in 2006, and the 210 horsepower (160 kW) 3.7 L V6. However, the Cherokee was not the first Jeep vehicle to make use of an independent front suspension, as the Jeep Wagoneer first used it in the 1963 model. But, that independent front suspension was limited to four wheel drive variations and, even then, was a short lived option. In addition, the Cherokee had been nominated for the North American Truck of the Year award for 2002.

Three trim levels were initially provided; the top end Limited, a more rugged looking Renegade and the base Sport. All were made available with either 2WD or 4WD. In 2005, all Cherokee received a small facelift. The 2005, 2006 Renegade and 2005 Rocky hill Edition Liberties received an exclusive flat hood and taller grille. In 2007, the Renegade trim level had been replaced with the Latitude which appeared to focus more on an urban appearance and lost the Renegade trim's unique grille and hood. The Cherokee is available with either a part-time Command-Trac or full-time Selec-Trac transfer case.

The Command-Trac transfer case has four positions: 2-HI, 4-HI, Neutral, and 4-LO. The lever is placed in 2WD HI for regular driving. This allows the two back tires to get energy. The second position, 4WD HI, is used for driving on slippery or loose surfaces. This position locks both the front and rear drive shafts together allowing the automobile to maintain drive as long as a minumum of one axle has traction. The third Neutral, position, disengages both drive shafts from the transfer instance enabling the automobile to roll freely; this is used for towing behind another vehicle, for example. The last position, 4WD LO is utilized for situations requiring greater torque or slow speed when traversing rough landscapes. A common misconception is that 4WD LO provides much more traction. It only changes the gear ratio and does not add any more friction between the tires and the driving surface. This position, like 4WD HI locks both the front and rear drive shafts together, and by making use of a lower gear ratio, allows for 2.72 times more torque (nevertheless, the speed is limited to around 25 MPH max). It should be noted that turning while in 4WD HI or LO on dry pavement is hazardous to vehicle components, through driveline binding and wheel-hop.

The Selec-Trac transfer case has five positions: 4-HI, 2-HI Part-Time, 4-HI Neutral, Full-Time, and 4-LO. The transfer case is different from the Command-Trac transfer only in the extra 4WD HI Full-Time position. The 4WD HI Full-Time position adds the same traction benefits that the part-time 4WD setting offers, but features an open differential between the front and rear axles to allow the two axles to spin at independent speeds and eliminate drive line binding and wheel-hop. The down part of 4WD Hi Full-Time is that, due to the open differential between front and rear drive lines, at times the drive train will just deliver power to the front or the rear e.g. when the front of the car has reached a high traction area such as dry pavement as well as the rear is in sand, the rear tires will spin with 100% of motor power, the front receiving no traction. Under equal traction conditions (front-rear) this position gives the rear tires 52% of the engine's energy and the front wheels 48% of the engine's energy. The unit of energy and available center differential allows the Selec-Trac transfer instance to be operated at all times in an "All Wheel Drive" mode with no adverse effects.

Even though no special Jeep Cherokee was introduced in 2002 for police use, police and rental companies continue to purchase it for fleet use. Many are equipped with the 3.7L "Power-Tech" V6 Engine that produces 210 horsepower mated to a 5-Speed Automatic Transmission, however, some fleet Liberties utilized a 2.5L I4 Engine that produced about 150 horsepower with a 4-Speed Automatic Transmission. In 2008, whenever the Jeep Cherokee was fully redesigned, the I4 motor was dropped, and the V6 engine was the only motor choice, as was the 4-Speed Automatic Transmission. Most fleet and government Liberties also use either the Selec-Trac or Selec-Trac II 4WD Systems, but some Liberties used 2WD.

Since it was introduced in late 2001 as a 2002 Model Year vehicle to the time it was discontinued in 2007, the Cherokee KJ also found its way into rental car fleets. Most rental Cherokee KJ's were the V6-powered Sport models with automatic transmissions and 4WD

Numerous variations were available in markets outside the U.S. and Canada.

Early-2002 through mid-2003 model year CRDs were equipped with a 2.5lt VM Motori Diesel producing 105 kW (143 PS; 141 hp) and 343
