Service bulletins for the 2020 Ram 1500

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

If you experience a vehicle with the above condition, please perform the proper maintenance procedures for the rear axle and replace the fluid first before replacing any hardware components. NOTE: This service bulletin is only applicable to vehicles that have no history of an axle fluid replacement. If the vehicle usage includes police, taxi, fleet, off-road or frequent trailer towing, regular axle fluid changes are required every 3 years or 30,000 miles (whichever comes first) per the Maintenance Schedule in the vehicle Owner's Manual.
