1995–2001 Dodge Ram 1500, 2500, 3500 Service Manual (P/N 81-370-5108)

This 1,794-page PDF reproduces Chrysler Corporation's factory service manual for the 1995 Dodge Ram 1500, 2500, and 3500. It covers the truck as a complete vehicle rather than treating the engine or drivetrain as a stand-alone subject. The material is suited to technicians and experienced owners who already understand automotive systems and have access to lifting equipment, precision measuring tools, electrical test gear, and the specified service tools; it is not a beginner maintenance guide.

• Exact 1995 coverage: 2WD and 4WD trucks, pickup and cab-chassis layouts, regular/conventional and Club Cab bodies, and single- or dual-rear-wheel applications where listed.
• Engine and fuel-system repair: engine removal and installation, cylinder-head and valvetrain service, timing-drive and lubrication work, gasoline multi-port fuel-injection testing, plus Cummins injection-pump timing, transfer-pump, injector, intake-heater, and water-separator diagnosis.
• Transmission and four-wheel-drive work: NV3500 and NV4500 teardown, inspection, reassembly, and adjustment; 42RH/46RH/47RH hydraulic diagnosis and overhaul; overdrive-unit repair; and NP231HD/NP241/NP241HD transfer-case removal, disassembly, inspection, and assembly.
• Axle, suspension, steering, and driveline service: IFS and link/coil front suspension, wheel alignment, Model 44/60 front axles, 9-1/4-inch and Model 60/70/80 rear axles, Trac-Lok/Power-Lok differentials, propeller-shaft angle and vibration diagnosis, power-steering pressure tests, and recirculating-ball steering-gear repair.
• Brake-system diagnosis and repair: front disc and rear drum brakes, master-cylinder overhaul and bench bleeding, power booster and diesel vacuum-pump tests, parking brakes, rear-wheel ABS, optional all-wheel ABS, hydraulic bleeding, and component-specific troubleshooting charts.
• Electrical and supporting systems: battery/starting/charging and ignition diagnosis, PCM inputs and outputs, airbags, instruments, speed control, power accessories, R-134a HVAC service, body and urethane-set glass repair, maintenance schedules, capacities, and wiring diagrams.

Configuration-Specific Repair Detail

Engine coverage includes the 3.9L V6, 5.2L V8, 5.9L V8, 8.0L V10, and turbocharged 5.9L Cummins inline-six diesel. The gasoline chapters distinguish the 5.9L LDC and HDC versions instead of treating both engines as interchangeable; the VIN section identifies them separately as engine codes Z and 5. It also provides codes X for the 3.9L, Y for the 5.2L, W for the 8.0L, and C for the Cummins diesel.

The transmission section is equally application-specific. NV3500 coverage applies to 3.9L and 5.2L installations, while the NV4500 chapter separates the standard-duty 5.2L/5.9L version from the heavy-duty V10/Cummins version. The 42RH is identified for 3.9L 4x2 1500 models; the 46RH serves gasoline V6/V8 applications; and the 47RH is limited to V10 and Cummins diesel trucks. An additional section covers removal, diagnosis, overhaul, and linkage adjustment for the optional NV021 PTO adapter used on 2WD 2500 and 3500 trucks with automatic transmission.

Diagnostics, Drawings, and Shop Data

The manual goes beyond remove-and-replace work. It contains axle noise and driveline-snap diagnosis, automatic-transmission hydraulic pressure, stall, and air tests, clutch diagnosis and NV4500 clutch-housing runout checks, cooling-system pressure tests, A/C performance and vacuum-control tests, body water-leak and wind-noise procedures, and gasoline and diesel diagnostic trouble-code charts.

Representative drawing coverage includes gasoline and diesel fuel/ignition circuits, 42RH/46RH/47RH transmission-control schematics, RWAL and all-wheel ABS circuits, NP231HD/NP241/NP241HD transfer-case exploded views, vacuum-hose routing schematics, and connector pin-out and location drawings. Tool callouts include terminal-release tool 6742 and probing package 6807, IAC motor exerciser 7558, cylinder-bore indicator 6879, propeller-shaft angle tool 7663, steering-wheel puller C-3428B, and A/C Tool Kit 6125.

Component-specific torque tables are backed by fluid-capacity data, alignment specifications, pressure-test ranges, electrical resistance and voltage charts, bearing preload and end-play data, gear backlash settings, wear limits, and transmission adjustment specifications. Separate light-duty, heavy-duty, and diesel maintenance schedules cover the required inspection and fluid-service intervals.

The book supplies DTC descriptions, component tests, and DRB scan-tool references, but directs full DRB operation and some PCM circuit testing to the separate Powertrain Diagnostic Procedures manual. It also warns that rubber-bushed suspension fasteners must be tightened at normal ride height; tightening them with the suspension hanging can accelerate bushing wear. Cleaned axle bearings must not be spun with compressed air because overheating can brinell the bearing surfaces. Use rated lifting and support equipment for heavy assemblies, and follow the manual's isolation and recovery precautions before airbag or refrigerant service.
