Jeep Cherokee XJ 2WD and 4WD Service & Repair Manual OEM 2001

• Covers 2000 and 2001 Jeep Cherokee XJ models in 2-door and 4-door body styles, with 2WD and 4WD configurations. The VIN tables identify model-year code Y for 2000 and 1 for 2001, while separating LHD, RHD, and export vehicle lines and the 2.5L gasoline, 4.0L gasoline, and 2.5L diesel engine applications.
• Includes DaimlerChrysler service publications, including the 2000 XJ Service Manual identified as Publication No. 81-370-0046 and the separate 2001 Service Manual Supplement. The 2001 supplement contains only material that was new or revised for that model year; unchanged 2001 repair information remains in the 2000 base manual, which is also included.
• The technical set totals 3,662 pages across seven PDF volumes: the 2,119-page 2000 service manual, 625-page 2001 supplement, and separate Body, Chassis/ABS, Gas Powertrain, Diesel Powertrain, and AW4 Transmission diagnostic manuals.
• Repair coverage extends well beyond routine maintenance, with internal engine service, AX5 and NV3550 manual transmissions, 30RH and AW4 automatics, NV231 and NV242 transfer cases, 181-FBI and 186-FBI front axles, 194-RBI and 8¼ rear axles, suspension, brakes, HVAC, body systems, electrical diagnosis, and drivetrain setup procedures.

Covered Systems and Technical Data

Lubrication and capacity tables cover the engine, transmission, transfer case, and both axles. The 2001 specifications list the 181-FBI front axle at 1.48 L and the 186-FBI at 1.18 L. Transmission and transfer-case data include separate figures for AW4 service and overhaul fills, NV3550 lubricant capacity, and NV231/NV242 capacities. Trac-Lok rear-axle applications are identified with their required friction-modifier quantities rather than being treated as the same fill as an open differential.

Chassis sections cover caster, camber, and toe checks along with shocks, coil springs, upper and lower control arms, stabilizer bars, track bars, steering knuckles, and the one-piece front hub/bearing assembly. Propeller-shaft coverage includes joint-angle measurement, runout checks, universal joints, and shaft removal and installation. The axle chapters go into actual differential setup: pinion depth, pinion-bearing preload, differential-bearing preload, ring-gear backlash, and gear-tooth contact-pattern interpretation for the FBI and RBI axle families and the 8¼ rear axle.

Engine material covers the 2.5L and 4.0L gasoline engines through cylinder-head, valve-train, timing-chain, camshaft, piston, connecting-rod, crankshaft, rear-main-seal, oil-pump, and cylinder-block repair. Separate diesel sections and a dedicated 2001 diesel diagnostic volume cover the 2.5L diesel application. Transmission sections identify AX5, NV3550, 30RH, and AW4 service, plus NV231 and NV242 transfer-case work. The 2000 publication also distinguishes early- and late-build exhaust-pipe, catalytic-converter, muffler, and tailpipe layouts for relevant gasoline-engine configurations.

Diagnostics, Wiring, and 2001 Updates

The separate 2001 diagnostic books add DRBIII-based fault finding that is not apparent from a basic chassis-and-torque overview. Body diagnostics cover the Airbag Control Module, CCD bus communication, Instrument Cluster, Compass/Mini-Trip Computer, Remote Keyless Entry, and Sentry Key Immobilizer System. Chassis diagnostics cover the Teves Mark 20 ABS/CAB system. Gas powertrain diagnostics cover the 4.0L JTEC system, while the diesel book addresses ECM/PCM and SKIM-related faults, no-start conditions, sensor checks, glow-system faults, EGR, fuel-injection-pump issues, and turbocharger-related diagnosis.

The AW4 diagnostic volume is specific to the electronically controlled transmission used with the 4.0L application and includes the Transmission Range Sensor, input and output speed sensors, solenoid circuits, TCM/PCM CCD-bus communication, DTC procedures, connector pinouts, and component-location views. Wiring coverage includes LHD/RHD component locations, connector and splice identification, and system schematics. Representative titles include 2001 JEEP XJ 4.0L JTEC SYSTEM, Vehicle Communication, Instrument Cluster, Transmission Connectors 4.0L Eng, Headliner Splices, and 2000 XJ Teves Mark 20 Antilock Brake System.

Torque Parameters and Service Specifications

The axle data gives measurable setup targets rather than generic adjustment language. For the 181-FBI and 186-FBI front axles, the 2001 specification table gives ring-gear backlash of 0.12–0.20 mm (0.005–0.008 in) and pinion rotating preload with new bearings of 1.7–3.4 N·m (15–30 in-lb). The 8¼ rear-axle procedure specifies a final backlash range of 0.15–0.203 mm (0.006–0.008 in). Major fastener tables include values such as the front axle-shaft nut at 237 N·m (175 ft-lb) and hub/bearing mounting bolts at 102 N·m (75 ft-lb).

Factory-tool references show the repair depth of the axle and suspension sections. Examples include C-4150A for wheel-stud removal, 6958 for holding the pinion yoke, C-3972-A with handle C-4171 for pinion-seal installation, and pinion-depth tooling from sets 6774/6987. These references are particularly useful when planning a differential rebuild or determining whether a repair requires tooling beyond normal shop equipment.

Several cautions are specific enough to prevent expensive mistakes. In front-axle pinion service, the manual warns against backing off the pinion nut to reduce rotating torque; over-crushing the collapsible spacer changes bearing preload and can require spacer replacement. During ABS-equipped axle-shaft work, the pressed-on tone ring and nearby wheel-speed sensor are specifically identified as damage-sensitive. The cooling-system sections also identify the reverse-rotation water-pump arrangement used on the gasoline engines; an incorrect pump or incorrect belt routing can result in improper pump rotation and engine overheating.

Before axle, suspension, driveline, brake, or underbody repair, use the manual’s specified hoisting and support locations so the unibody and loaded components are supported correctly.
