Dodge RAM 1500/2500/3500 Factory Service Manual 2006

This factory service manual covers the 2006 Dodge Ram 1500, 2500, and 3500 line, with configuration-specific material for SRT-10, Power Wagon, 3500 Cab Chassis, and Mexico Work Truck builds.

Text Search, Bookmarks, and Wiring Detail

Finding procedures and circuit details: Service text is searchable, but many wiring-diagram labels are not. Embedded bookmarks cover the main service groups and many individual procedures; three introductory entries have no destination within this file. Dense schematics require zooming to read small wire codes, connector identifiers, and pin numbers.

Supplied as one printable, English-language, 9,267-page PDF. The total includes the section locator, indexes, 33 blank pages, and the two-page service-comment form.

Powertrain Repair, Chassis Setup, and Circuit Diagnosis

The following highlights are a selection of the manual's contents. Other covered subjects include winch repair and sunroof service.

• Engine repair: Step-by-step engine removal and installation, cylinder-head and valvetrain work, internal inspection, lubrication service, and timing-system procedures for the applicable engine.

• Transmission and transfer cases: Mechanical and electrical diagnosis, internal disassembly, inspection, reassembly, clutch and valve-body service, adjustments, and post-repair verification.

• Axles and suspension: Pinion-depth setup, bearing preload, backlash and tooth-contact checks, wheel alignment, suspension repair, and Power Wagon locker and stabilizer diagnostics.

• Brakes and steering: Base-brake, rear-wheel ABS, and all-wheel ABS diagnosis, manual and pressure bleeding, hydro-boost checks, caliper service, and power-steering pressure testing.

• Electrical troubleshooting: System wiring diagrams, connector pin-outs, splice and ground locations, harness-routing views, and wire and terminal repair procedures.

• Body and support systems: Hydroform fender-rail and rear frame H-section repair, body dimensions, HVAC diagnostics and refrigerant service, restraints, and EVAP/EGR diagnosis.

This shop-level material is suited to professional technicians and experienced mechanics with the lifting equipment, scan tools, electrical test gear, A/C service equipment, and drivetrain setup tools required for their work. Certain driver-airbag procedures are specifically restricted to DaimlerChrysler-trained and authorized dealer technicians.

Engine, Fuel, and Cooling Work

Mechanical sections cover the 3.7L V6, 4.7L V8 gasoline and flex-fuel versions, 5.7L V8, 5.9L Cummins turbo diesel, and 8.3L SRT-10 V10. Separate maintenance information addresses the 24-valve Cummins and SRT-10 configurations.

Engine diagnosis extends to compression and combustion-leak testing, cylinder-bore and crankshaft measurement, piston and bearing fitting, oil-pump service, valve and seat work, and timing-chain verification. Gasoline, diesel, and SRT-10 electrical diagnostics have separate sections.

Fuel-system chapters distinguish gasoline delivery and injection from diesel injection-pump, injector, rail, and fuel/water-separator work. Turbocharger inspection and charge-air-cooler service accompany the diesel material. Cooling coverage includes pressure testing, thermostat and water-pump service, and engine-specific plumbing.

Transmission Coverage and Configuration Checks

Dedicated repair sections address the G56, Getrag 238, and T56 manuals, plus the 42RLE, 45RFE/545RFE, and 48RE automatics. RFE material includes hydraulic-pressure checks, clutch-application charts, and Quick Learn procedures; 48RE electrical diagnostics distinguish gasoline and diesel applications.

NV4500 and NV5600 limitation: These units appear in the identification table, but there are no dedicated teardown or overhaul chapters for them. Transfer-case repair sections cover NV241 Gen II, NV243, NV244 Gen II, NV271, and NV273 units, distinguishing mechanically shifted and electronically controlled systems.

VIN and body-code-plate decoding identifies cab and box styles, drive type, price class, engines, and transmission sales codes. These distinctions help match the truck's configuration to the applicable procedures before parts or test specifications are selected.

Axle Setup and Chassis Variants

The axle chapters cover C205FD and 9 1/4 AA front units, plus 9 1/4, 10 1/2 AA, 11 1/2 AA, and 248RBI rear units. Setup procedures distinguish pinion-depth shims, differential-bearing preload, ring-gear backlash, and tooth-contact patterns. Power Wagon diagnostics address the Final Drive Control Module, locker solenoids, axle-position sensors, and disconnecting stabilizer bar.

Chassis information separates light-duty, heavy-duty, dual-rear-wheel, and SRT-10 applications. Brake service also includes parking-brake adjustment and variant-specific SRT-10 procedures.

Wiring, Diagnostic Charts, and Shop References

The 8W group includes Integrated Power Module, Ground Distribution, Bus Communications, Fuel/Ignition System, Transmission Control System, and All Wheel Antilock Brakes diagrams. DTC-specific test charts connect pre-diagnostic checks, intermittent-condition testing, circuit fault isolation, scan-tool data, and verification procedures, supporting diagnosis of the circuit involved rather than replacement based on a fault code alone.

Component torque tables, fluid types and capacities, alignment data, electrical test values, pressure specifications, clearances, wear limits, and calibration data accompany the service instructions. Tool illustrations identify Pinion Depth Sets 6730 and 6775, Probing Tool Package 6807, Terminal Pick Tool Set 6680, cooling-system pressure tester 7700, and Miller Special Tool 8815.

Exploded assemblies and section views support the written procedures. Frame and body references add structural-adhesive and weld locations, frame measurements, and body-opening dimensions.

Component damage cautions: Axle procedures warn that attempting to reduce pinion-bearing rotating torque by loosening the pinion nut can damage the axle or collapsible spacer. PCM diagnostic charts warn that direct connector probing can damage terminals and create poor pin connections.

Fuel pressure, hot cooling systems, heavy drivetrain components, spring-loaded parts, refrigerant, ABS, and supplemental restraints require the safety controls and equipment stated in the manual. This publication does not replace the training or authorization required for hazardous or restricted repairs.

A Preview of 42RLE Inspection Specifications

The 42RLE section lists input-shaft end play of 0.127–0.635 mm (0.005–0.025 in.) alongside its inspection and assembly information.

For the same transmission, low/reverse clutch-pack clearance is 0.84–1.60 mm (0.033–0.063 in.), with a selective reaction plate specified. Selective-plate information accompanies the clutch-pack inspection and assembly procedures.
