1995 Jeep Wrangler YJ Factory Service & Repair Manual (P/N 81-370-5146)

• Covers 1995 Jeep Cherokee XJ and Wrangler YJ systems with the 2.5L inline-four and 4.0L inline-six, including 2WD and 4WD driveline applications, XJ left- and right-hand-drive electrical layouts, and model-specific identification data.
• Engine sections document compression and leakage diagnosis, engine removal and installation, cylinder-head and valvetrain service, timing-chain and camshaft work, oil-pump inspection, and piston, connecting-rod, crankshaft, and main-bearing repair.
• Transmission coverage identifies the AX4/AX5, AX15, 30RH, 32RH, and AW-4 applications, then provides diagnosis, removal, adjustment, internal disassembly, inspection, overhaul, and assembly procedures. The NP231 Command-Trac and XJ-only NP242 transfer cases receive full removal and overhaul coverage.
• Chassis procedures include Model 30 front axle and 2WD tube-axle service, Model 35 and 8 1/4 rear axle work, Trac-Lok differential service, ring-and-pinion setup, suspension alignment, ball-joint replacement, steering-gear repair, brake bleeding, disc/drum repair, and ABS service.
• Electrical and drivability material includes multi-port fuel-injection diagnosis, PCM inputs and outputs, ignition and charging tests, 2.5L/4.0L fuel/ignition circuits, transmission-control diagrams, ABS wiring, connector pin-outs, connector and splice locations, and the Disconnect Axle/Shift Motor Diagnosis chart.
• Adds a focused 112-page ATSG Jeep AW-4 booklet covering preliminary diagnosis, troubleshooting charts, hydraulic-pressure, stall, and time-lag tests, transmission and torque-converter removal, case and subassembly overhaul, valve-body teardown, reassembly, and neutral-safety-switch adjustment.

XJ/YJ Coverage and File Identity

This download contains 2,295 PDF pages total: a 2,183-page 1995 Jeep Cherokee/Wrangler factory service manual compilation, identified on the included update sheets as Chrysler Publication No. 81-370-5146, plus the 112-page ATSG Jeep AW-4 booklet. The main PDF reproduces Chrysler factory repair material but carries a Pacific Coast Manuals cover and footer; the transmission booklet is an ATSG publication based on Chrysler illustrations and information. This is a compiled two-file set, not two untouched original-print scans.

The factory foreword states that the service information was prepared for professional automotive technicians involved in daily repair operations. Its overhaul depth and reliance on scan tools, pressure gauges, pullers, presses, and measuring equipment also make it suitable for experienced owners working in a properly equipped shop.

Engine, Transmission, and Axle Work

Application notes help prevent parts and procedure mix-ups. The AX4/AX5 manual transmission is paired with the 2.5L engine, while the AX15 is used with the 4.0L. The 30RH covers 2.5L XJ/YJ applications; the 32RH applies to 4.0L YJ models; and the electronically controlled AW-4 is used with the 4.0L XJ. NP231 coverage applies to both XJ and YJ, while the full- and part-time NP242 section is specific to the XJ.

Axle work goes well beyond seal replacement. The manual includes bearing and gear-noise diagnosis, differential removal, pinion-depth measurement, bearing-preload and backlash setup, tooth-contact pattern analysis, axle-shaft and U-joint work, and Command-Trac vacuum-disconnect testing. Named equipment includes axle spreader W-129-B, dial indicator C-3339, flange wrench C-3281, AW-4 overhaul Tool Kit 6294, and pressure-test adapter 7554.

Diagnostics, Schematics, and Shop Limits

The diagnostic material combines symptom charts with component tests and system schematics. Representative examples include 2.5L and 4.0L fuel/ignition diagrams, AW-4 TCM and solenoid circuits, ABS brake-line and wiring layouts, XJ/YJ heating schematics, and connector pin-out and location views. Torque tables, fluid capacities, approved lubricants, electrical test data, pressure-test specifications, wear limits, alignment values, and transmission/axle adjustment data are distributed through the applicable groups rather than isolated in a generic reference section.

Cooling and HVAC chapters add cooling-system diagnosis, radiator, fan, thermostat, and water-pump service, refrigerant performance tests, compressor procedures, and model-specific heater components. Body coverage extends to XJ and YJ doors, glass, exterior and interior hardware, plus YJ top and windshield-frame work.

The repair cautions are assembly-specific. During 30RH/32RH removal or installation, the crankshaft position sensor must be removed first or it can be damaged. In differential setup, exceeding preload on a new collapsible pinion spacer cannot be corrected by backing off the nut; the spacer must be replaced to avoid an incorrect bearing setting and resulting gear damage.

Full DRB scan-tool operation and some PCM/ABS fault-tree diagnosis refer to separate Powertrain or chassis/body diagnostic publications, which are not part of this set. Theory of operation and owner-level equipment instructions are also outside the factory manual's stated scope. Because the repair sections include vehicle lifting, brake hydraulics, pressurized fuel, and refrigerant service, use rated support equipment and the specified test or recovery tools before opening those systems.
