46-70392: The current exact manufacturer listing covers 2003-2018 Dodge/Ram 2500/3500 with AAM 11.5/11.8 rear axles, broader than the old store title's 2014-2018 wording. The exact manual names 5.9L diesel 2003-2007, 6.7L diesel 2007-2018, 5.7L gas 2010-2018 and 6.4L gas 2014-2018. Exact-part named tables restore missing earlier Dodge and Ram groups and the supported 2005 SLT/ST gaps. Other original bounds and gaps are retained. Verify the actual axle, coil/leaf-spring layout, brake bracket and boxed revision; the engine headings do not approve every axle supplied in those trucks.

Which applications and axle must be checked?The current exact manufacturer listing covers 2003-2018 Dodge/Ram 2500/3500 with AAM 11.5/11.8 rear axles, broader than the old store title's 2014-2018 wording. The exact manual names 5.9L diesel 2003-2007, 6.7L diesel 2007-2018, 5.7L gas 2010-2018 and 6.4L gas 2014-2018.

Verify the actual axle, coil/leaf-spring layout, brake bracket and boxed revision; the engine headings do not approve every axle supplied in those trucks.
Which plugs and sight glass are included?M12 x 1.25 magnetic drain plug with crush washer, 1/8-inch npt calibration plug, 3/4-inch npt magnetic fill plug with a 6-inch reach, and pre-installed 1-inch npt sight glass. The black cover's sight glass is pre-installed. The plain 1-inch side-plug and plain 3/4-inch fill-plug steps belong to the raw 46-70390 version.
Which mounting hardware is supplied?One black cover 05-60812B, fourteen M8 x 1.25 x 30 screws, three M8 x 1.25 x 40 screws, seventeen flat washers, three spacers, M12 magnetic drain plug/crush washer, 1/8-inch calibration plug, 3/4-inch magnetic 6-inch fill plug and pre-installed sight glass. Longer screws replace short screws at the applicable brackets; the cover has a fourteen-bolt pattern.
Does the cover include a gasket and gear oil?Gear oil, axle additive, filters, couplers and tools are not established as included. Reuse the original OEM gasket as directed by this exact manual. A new gasket, RTV, gear oil or axle additive is not established in its bill of materials.
How is the oil level set?Fill until oil flows from the side 1/8-inch calibration opening, about 4 quarts in the illustrated installation. Use the actual axle oil/additive specification and independently verify level if a lift has rotated the axle.
Which tightening values apply?Tighten the mounting screws to 12-16 ft-lb in a crisscross pattern. This exact manual provides no numerical M12 drain or sway-bar fastener torque and no NPT turn count; do not borrow those values from another cover.
What access and installation steps matter?Block the tires on a flat dry surface and position a drain pan. Retain upper cover hardware while draining, then remove the cover. Clean and inspect the flat sealing face without gouging or rounding it. Reuse the original OEM gasket as directed by this exact manual. A new gasket, RTV, gear oil or axle additive is not established in its bill of materials. Where fitted, retain the brake-line bracket and brake cable pad. Restore the bracket with two long screws, two spacers and four washers; restore the cable pad with the third long screw, spacer and two washers. On coil-spring vehicles only, remove the four sway-bar bolts for access, then reinstall the sway bar using those original bolts. Install the appropriate hardware, fill by the specified level opening and inspect clearance and leaks. Follow the exact supplied revision.
