5th Gen Ram 1500 Rear Differential Fluid Change Info
The rear differential gear oil change procedures apply to 1500 models as listed below:
- 2019-2023 Ram 1500 rear differential fluid change for 4WD Models (5th Gen).
- The demonstration was performed on a 2019 Ram 1500 with a 3.21/3.55 type rear differential. 3.92 rear differentials will look different however the drain, fill, and fluid leveling process will be the same. 3.92 rear differential will have a rubber fill plug in the rear differential cover.
Ram 1500 Rear Differential Fluid Change Interval
When should you change your Ram 1500 rear differential fluid? While it's always best to follow the manufacturers' recommendations, changing the Ram gear oil every 50,000 miles to 60,000 miles should be acceptable under usual driving conditions. However, if your truck experiences more aggressive driving, full-time/consistent 4WD engagement, off-roading, and/or frequent trailer pulling, servicing the differential fluids more frequently—like every 30,000 miles—would be recommended. Also, if using a cheaper, non-synthetic brand of fluid, the differential fluid will need to be changed more often. Following the recommended Ram 1500 rear differential fluid change intervals and the recommendations noted here can eliminate and minimize mechanical issues and costly differential repairs.
Why Should Ram 1500 Rear Differential Fluid Gear Oil Be Changed?
Your rear Ram 1500 differential has a good amount of moving internal components. This includes bearings, pinion gears, and crown gears. These internal components rely solely on the diff fluid's lubrication film strength for protection and longevity. The diff fluid experiences excessive shear loads and various heat cycles through use. In time, these heat cycles and extreme loads deplete the differential fluid's lubricating properties and film strength. Continued use of old differential fluid will result in differential bearing, pinion gear wear, and failure. Therefore, having regular rear differential fluid changes is essential. Changing the Ram 1500 differential fluid as routine maintenance will significantly extend the life of the rear differential, minimize driveline noises due to wear, and ensure the bearings and gears receive reliable, clean lubrication.
