Component and System Documentation

The manual delivers deep coverage of core mechanical systems for the third-generation RAM. You get detailed suspension geometry data, including caster, camber, and toe settings for all wheelbase setups. It breaks down the front and rear axle assemblies, specifically focusing on the C205F and 9 1/4-inch units. The documentation traces everything from basic hub and bearing removal to precise pinion and ring gear assembly.

Electrical sections map out component locations and diagnostic routines for the modular electronic control systems. For daily shop operations, the lubrication chapter outlines exact fluid specifications for the engine, transmission, transfer case, and differentials. Working on these heavy drivetrain assemblies involves dealing with high vehicle weight and stored energy. Always verify the designated hoist points and secure the truck on adequately rated jack stands before getting under the chassis to inspect these systems.

Specification and Reference Data

Accurate technical data drives efficient diagnostics and prevents re-work. Critical torque values are mapped out clearly throughout the chapters. For example, lower control arm frame nuts require a specific 204 Nm (150 ft-lbs). If you are servicing the 4.7L engine, the specification tables confirm a coolant system capacity of 15.4 liters.

Servicing the 9 1/4-inch rear axle takes exactly 2.32 liters of gear oil. Additionally, four-wheel-drive hub and bearing mounting bolts must be torqued down to 163 Nm (120 ft-lbs). Having these hard numbers readily available eliminates guesswork during complex teardowns and speeds up the overall turnaround time in the bay.
