Dodge Ram 2500 Rear Axle Torque Specs
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| Cover / fill plug | 40 / 32 N·m | 30 / 24 lb-ft |
| Bearing-cap bolts | 281 N·m | 207 lb-ft |
| Ring-gear bolts | 237 N·m | 175 lb-ft |
| Axle-flange bolts | 129 N·m | 95 lb-ft |
Pinion torque-to-rotate is a preload measurement, not a pinion-nut final torque: the table lists 15–25 in-lb for new pinion bearings and 10–20 in-lb for original bearings. Use the full setup procedure for backlash, preload and fastener replacement rules.
The 11.5-inch AA row must be identified first
The covered Ram manual also includes 10.5-inch and 302RBI rear-axle tables. These values belong only to the 11.5-inch AA assembly; confirm axle identity, ratio and service history before tightening internal parts.
The table lists 3.73 and 4.10 ratios and a 292-mm ring gear for this axle. Those descriptors help identification but do not replace the axle tag and parts information.
Rotating torque is a preload measurement
For new pinion bearings the table gives 15–25 in-lb of torque to rotate; original bearings use 10–20 in-lb. These are measured rotational-resistance targets after setup, not values to dial into a wrench on the pinion nut.
Internal work also requires 0.005–0.007-in ring-gear backlash and the complete contact-pattern procedure. Use the cover, cap, ring-gear and flange bolt values only with the specified fastener preparation and sequence.
