Jeep Wrangler TJ 2000 Service Manual (P/N 81-370-0048)

This Chrysler factory service manual (P/N 81-370-0048) covers the 2000 Jeep Wrangler TJ with the 2.5L EPE four-cylinder or 4.0L ERH six-cylinder MPI gasoline engine. It covers left- and right-hand-drive configurations.

PDF Search, Bookmarks, and Diagram Detail

Text search and diagram labels: Workshop text and component indexes are searchable. Embedded bookmarks open the main service groups, while three entries point to separate files. Circuit drawings and connector pinout labels are graphics, so use the indexes to locate them and zoom in to read small pin numbers and wire codes.

The download is one printable PDF with 1,407 pages. The total includes 32 pages in supplemental sections, 12 pages carrying service bulletin updates, a one-page chapter locator, a two-page feedback form, and 30 blank separator pages.

Engine, Drivetrain, and Electrical Service

These are selected workshop procedures and references. The manual also covers starter feed-circuit voltage-drop testing and wiper system diagnosis.

• Engine and cooling: Engine removal, short-block service, cylinder-head and valve work, timing chain and sprocket replacement, camshaft and bearing service, and cooling-system diagnosis.

• Fuel and emissions: Fuel pump pressure, delivery, and leak-down tests, injector checks, PCM VIN reprogramming, and onboard emissions diagnostics.

• Clutch, transmissions, and transfer case: Clutch service and teardown, inspection, reassembly, and adjustment procedures for the AX5, NV3550, 30RH/32RH, and NV231.

• Axles, driveline, and suspension: Propeller-shaft vibration, balance, runout, U-joint, and angle checks, plus differential setup, wheel alignment, and link-and-coil suspension service.

• Brakes and steering: Base brake and ABS diagnosis, disc and drum brake service, master-cylinder and system bleeding, and power-steering flow and pressure testing.

• Electrical troubleshooting: Group 8W covers power and ground distribution, circuit diagrams, connector pinouts, splice and component locations, and wiring fault isolation and repair.

• Frame, body, and HVAC: Frame and skid-plate references, body opening dimensions, weld and sealer locations, and A/C performance tests, leak checks, and component replacement.

The manual is suited to repair technicians familiar with scan tools and specialized measuring equipment such as differential setup gauges.

Maintenance, Engine Checks, and Fuel Diagnosis

Normal and severe-duty schedules distinguish routine use from off-road driving, towing, dusty conditions, and extended idling. Engine chapters cover crankshaft, piston, and connecting-rod inspection, with oil-pressure and cylinder compression tests for assessing engine condition before teardown.

The emissions and fuel sections cover DTC descriptions, DRB III actuator tests, and state displays. For full scan-tool fault isolation on systems such as the injectors, the manual refers to the separate Powertrain Diagnostics Procedures manual.

Transmission Overhaul and Transfer Case Service

The AX15 appears in the body-code chart and fluid-capacity table. For an AX15 overhaul, use a dedicated AX15 reference. The NV3550 teardown and assembly pages incorporate updates marked TSB 26-04-01, and the manual gearbox chapters detail geartrain and synchronizer inspection.

The automatic transmission chapter pairs hydraulic schematics and pressure and air tests with valve-body, clutch, servo, and planetary geartrain service. It also covers band and cable adjustment. NV231 service extends to the drive chain, shafts, oil pump, range and mode forks, planetary assembly, seals, and shift linkage.

Axle Setup and Suspension

The 181 FBI front axle and 194 RBI and 216 RBI rear axle sections cover standard and Trac-Lok differentials, bearing preload, backlash, and gear tooth contact patterns. Setup references include Pinion Depth Gauge Set 6774, Axle Housing Spreader W-129-B, and Dial Indicator C-3339.

Suspension procedures cover hubs, ball joints, bushings, track bars, and stabilizer bars, with dedicated tools for ball joints and bushings. The manual calls for final tightening of rubber-bushed suspension arms at normal ride height. It also specifies replacing a collapsible pinion spacer if the bearing preload is exceeded during setup.

Wiring, Market Equipment, and Shop References

Use the power distribution and ABS diagrams with the connector, ground, and splice-location views to trace a circuit from the schematic to the vehicle. Group 8W also covers terminal replacement and connector repair. Assembly-specific torque charts, fluid capacities, wear limits, clearances, and electrical test values appear in the relevant service groups.

Market-specific pages cover remote headlamp leveling, rear fog lamp switches, emergency tow eyes, license plate brackets, and leaded-fuel applications. The exhaust chapter incorporates TSB 26-02-00 and distinguishes federal and California catalyst layouts and early- and late-build exhaust assemblies.

HVAC procedures cover refrigerant recovery, evacuation, and charging. Follow Chrysler’s specified support, isolation, recovery, and protective-equipment requirements for work involving a raised vehicle, airbags, brake hydraulics, fuel pressure, or refrigerant.

Fuel Delivery and Pinion Setup Examples

The DRB fuel pump capacity test specifies at least 0.25 L in 7 seconds. The manual uses this delivery check alongside the pressure and leak-down tests to narrow down fuel supply faults.

For the 216 RBI rear axle, the standard pinion depth is 4.312 in. (109.52 mm). The differential setup procedure uses that dimension as the reference for the depth variance marked on the pinion.
