1996 Jeep Grand Cherokee Laredo, Limited & SE 4.0L & 5.2L Repair Manual (P/N 81-370-6147)

• Matches the 1996 Jeep Grand Cherokee ZJ in Laredo, SE, and Limited series. Engine coverage includes the 4.0L inline-six and 5.2L V8, while the VIN section identifies 4x2 LHD, 4x4 LHD, and 4x4 RHD vehicle lines. This 1,546-page PDF compilation contains Chrysler factory service content from Publication No. 81-370-6147, the 1996 supplement, and incorporated Chrysler TSB pages dated as late as December 1996.
• Supplemental sections add updated fluid-capacity data, the aluminum Model 44 rear axle, and the NV242 transfer case, with diagnosis, internal repair, adjustment, specification, and special-tool coverage for those additions.
• Engine, fuel, and cooling coverage reaches from compression, combustion-leak, oil-pressure, fuel-pressure, leak-down, and cooling-system testing through engine removal, cylinder-head and valve repair, timing-chain and camshaft work, piston and bearing inspection, oil-pump service, and component-level PCM sensor and actuator checks.
• For the 42/44RE automatic transmission, the manual documents road-test analysis, hydraulic-pressure, air, and converter-stall testing; valve-body, clutch, planetary, and overdrive overhaul; band and cable adjustment; hydraulic schematics; and transmission or torque-converter removal and installation.
• Driveline and suspension sections cover wheel alignment, link/coil assemblies, hub/bearings, control arms and track bars, single- and double-Cardan propeller shafts, tube/Model 30 front axles with Selec-Trac service, Model 35 and Model 44 rear axles, Trac-Lok differentials, and NV231, NV242, and NV249 transfer cases.
• Brake, steering, electrical, body, HVAC, and emissions chapters include four-wheel disc and ABS service, steering-gear overhaul, system wiring diagrams, connector pin-outs and locations, door/glass/liftgate repair, ATC testing, refrigerant service, and EVAP/OBD reference information.

Axle, Transfer Case, and Transmission Repair Depth

The axle chapters do more than identify parts. They take the technician from gear, bearing, vibration, and driveline-snap diagnosis through axle-shaft, seal, hub, differential, and pinion service. Factory setup coverage includes pinion-depth measurement, shim selection, differential-bearing preload, ring-gear backlash, tooth-contact pattern analysis, and final assembly for the covered axle families. The supplemental aluminum Model 44 section adds Trac-Lok testing and disassembly, axle-shaft bearing and seal work, collapsible-spacer service, and its own specification and torque references.

Transfer-case coverage distinguishes the part-time NV231, full- and part-time NV242, and full-time NV249 systems before parts or procedures are selected. Each chapter includes identification, symptom diagnosis, removal, internal disassembly and reassembly, cleaning and inspection, shift-linkage adjustment, sealing information, and model-specific special tools. Dedicated tool pages identify fixtures by number, including C-3292/C-3293SP transmission pressure gauges, pinion-depth sets 6774 and 6955, Trac-Lok service tools, and the W-129-B axle spreader.

Wiring Diagrams and System Diagnostics

The electrical section is organized as a full vehicle-circuit reference, with system schematics tied to power feeds, grounds, connectors, and splice locations. Representative factory sections include 8W-11 Power Distribution, 8W-30 Fuel/Ignition Systems, 8W-31 Transmission Control System, 8W-35 All-Wheel Anti-Lock Brakes, 8W-42 Air Conditioning/Heater, and 8W-45 Body Control Module. Connector pin-outs, connector-location views, splice locations, ground distribution, terminal repair, and wiring troubleshooting support fault tracing at the vehicle.

Mechanical and body-system diagnosis is similarly specific. The brake chapters include four-wheel disc and parking-brake service, master-cylinder and caliper repair, rotor machining, manual bleeding, ABS hydraulic-control-unit service, wheel-speed sensors, and ABS bleeding. Steering coverage reaches inside the gear to the pitman shaft, spool valve, rack piston, and worm shaft. Body and climate sections address water leaks, wind noise, stationary glass, sunroof and liftgate repair, ATC fault-code and circuit testing, refrigerant recovery/evacuation/charging, heater-core work, and evaporator service.

Companion Diagnostic Manuals and Repair Cautions

Some DRB scan-tool fault isolation and trouble-code routines are referred to separate Chrysler Powertrain Diagnostic Procedures, Body Diagnostic Procedures, or Chassis Diagnostic manuals; those companion publications are not included in this PDF. The service manual still supplies the component descriptions, mechanical diagnosis, wiring, removal and installation procedures, adjustments, specifications, and repair data listed above.

The axle sections flag the collapsible spacer and ring-gear bolts as one-time-use parts; reusing or over-crushing them risks incorrect pinion-bearing preload and insecure ring-gear fastening. The starting-system chapter also warns that striking the permanent-magnet starter, clamping it by the field frame, or reversing polarity during testing can damage its magnets. For axle, transmission, brake, fuel, A/C, and airbag work, use rated lifting equipment and follow the manual’s pressure-release, electrical-isolation, and component-handling warnings.
