Jeep Grand Cherokee WK/WH 2005 Service & Repair Manual

The DaimlerChrysler Electronic Service Manual for the 2005 Jeep Grand Cherokee covers WK 4x2 and 4x4 applications plus WH 4x4 left- and right-hand-drive applications. Vehicle identification includes Laredo and Limited trim.

PDF Search, Bookmarks, and Wiring Detail

Text search and diagram navigation: Service text is searchable throughout most sections, but many wiring sheets are not text-searchable. Extensive bookmarks navigate systems and component procedures; the welcome and foreword bookmarks point to separate files not included in the ZIP. Small wiring labels require zooming, and some fine diagram lines are faint.

One printable English PDF is supplied in a ZIP archive: 7,203 pages total, including three front-matter pages, 35 blank pages, and two service-comment pages.

Engine, Drivetrain, and Vehicle-System Repair

The following selected coverage highlights outline major repair and diagnostic areas. Additional topics include tire-pressure monitoring and wiper/washer system diagnosis.

• Gasoline-engine repair: Step-by-step engine removal, cylinder-head and valvetrain service, timing-component work, crankshaft and piston inspection, lubrication-system repair, and reassembly for 3.7L, 4.7L, and 5.7L engines.

• Axles and driveline: C200F/C200FE front and C213R/C213RE rear axle overhaul, propeller shafts, half shafts, CV joints, electronic limited-slip differentials, and Vari-Lok information.

• Transmissions and transfer cases: 545RFE and NAG1 diagnosis, pressure testing, clutch air checks, and internal repair; NV140/NV245 teardown and assembly, plus NV245 electronic diagnosis.

• Suspension, brakes, and steering: Alignment, hubs, knuckles, ball joints, control arms, springs, shocks, stabilizers, track bar, brake bleeding, ABS/ESP diagnosis, sensor calibration, and steering service.

• Electrical and restraint diagnosis: Module communication tests, wiring diagrams, connector views, charging and starting checks, occupant-classification tests, and restraint-controller fault tracing.

• Body and HVAC: Door, liftgate, glass, sunroof, and seat-system repair; ATC/MTC diagnosis, HVAC housing service, and refrigerant-system procedures.

• Fuel, cooling, and emissions: Fuel-pressure diagnosis, pump and injector service, cooling-system testing, thermostat and water-pump replacement, and evaporative-emission system checks.

Written for professional automotive technicians involved in daily repair work, the manual uses scan-tool diagnostics, specialized service tools, and workshop test equipment.

Gasoline-Engine Repair and Diesel Scope

The gasoline-engine chapters document cylinder-head and valve service, timing drives, camshafts, rocker arms and tappets, crankshaft and bearing inspection, pistons and connecting rods, oil pumps and pans, manifolds, mounts, seals, and final assembly checks.

Fuel-system material adds pressure-release procedures, fuel-pump module and fuel-rail removal, injector service, and throttle-control information. Cooling coverage includes leak diagnosis, pressure testing, accessory-drive service, and hydraulic cooling-fan operation. Emissions sections explain OBD II monitors, purge controls, and natural-vacuum leak detection.

The WH 3.0L turbo-diesel application appears in vehicle identification and relevant cooling, steering, electronic-module, NAG1-related, and wiring material. This PDF does not contain a dedicated internal 3.0L diesel-engine repair chapter; the mechanical engine-repair chapters cover the gasoline engines.

Transmission, Transfer-Case, and Axle Overhaul

The transmission sections identify internal clutch groups, planetary gearsets, pumps, valve-body or electrohydraulic control components, solenoids, speed sensors, torque converters, and adjustment data. Road tests, hydraulic pressure checks, clutch air checks, and verification procedures support diagnosis alongside teardown and assembly instructions.

The NV140 section covers the Quadra-Trac I transfer case. NV245 material addresses Quadra-Trac II and Quadra-Drive II applications, including shift-motor and mode-sensor diagnosis, seals, and fluid service.

Axle procedures cover differential disassembly, bearing and seal replacement, pinion-depth and bearing-preload setup, backlash adjustment, and gear-contact checks. The rear-axle instructions warn that excessive pinion preload can damage the collapsible spacer or bearings; backing off the nut is not an acceptable correction.

Chassis Diagnosis and Repair Precautions

Chassis sections combine front and rear suspension removal and installation with alignment inspection and adjustment. Brake coverage separates base-brake service from ABS/ESP diagnosis and calibration; steering material includes column service, gear replacement, and power-steering flow and pressure testing.

The suspension instructions warn that tightening rubber-bushed components with the suspension hanging can preload the bushings and cause premature wear.

Circuit Testing, Schematics, and Workshop References

System-specific DTC tests connect fault conditions with circuit checks and verification procedures, helping technicians trace communication, sensor, or actuator faults before selecting a repair. Coverage includes CAN-bus and no-response tests, power accessories, lighting, theft security, navigation, and audio systems.

Named drawing sections include 8W-10 Power Distribution, 8W-35 Antilock Brakes, 8W-43 Airbag System, 8W-80 Connector Pin-Outs, and 8W-91 Connector/Ground/Splice Location. The transmission sections also provide 545RFE and NAG1 hydraulic schematics.

Reference material includes component torque tables, approved fluids and capacities, Schedule A, Schedule B, export gasoline maintenance schedules, pressure-test specifications, wear limits, clearances, alignment data, electrical test values, and calibration information.

Special-tool callouts include Puller 8677, ball-joint tools 9654 and C-4212-3, power-steering flow/pressure Adapter 6825A, and transmission pressure gauges C-3292 and C-3293SP.

This publication describes work involving raised vehicles, heavy drivetrain assemblies, brake hydraulics, airbags, electrical isolation, and refrigerant handling. Repairs should be performed by qualified personnel using the factory safety procedures, specified support equipment, and the correct service tools.

Selected Axle-Setup and Steering-Test Specifications

For the C213R and C213RE rear axles, the specification tables list ring-gear backlash of 0.12–0.20 mm (0.005–0.008 in.) and ring-gear runout of 0.12 mm (0.005 in.), alongside the differential inspection and adjustment material.

For 3.7L and 4.7L applications, the power-steering pump chart specifies a flow rate of 2.6–3.0 GPM at 1,500 rpm within the flow-and-pressure testing section.
