Dodge Ram 1500 Rear Differential Fluid Capacity

Assuming you would like a blog titled “Dodge Ram 1500 Rear Differential Fluid Capacity”: The Dodge Ram 1500 is a light duty truck that was first introduced in 1994. It has been highly successful, with over six million trucks sold since its inception.

The Ram 1500 is available in both two-wheel and four-wheel drive configurations, and can be equipped with either a gasoline or diesel engine. One of the most important maintenance items on any truck is regularly checking and changing the differential fluid. This is especially true for the Dodge Ram 1500, as it has a larger rear differential than most trucks.

The capacity of the rear differential fluid depends on the model year of the truck, but is typically between two and three quarts.

The Dodge Ram 1500 is a great truck that can haul a lot of weight. However, one area that can be easily forgotten about when servicing this vehicle is the rear differential. The rear differential fluid capacity for the Dodge Ram 1500 is only 3.9 quarts.

This may not seem like much, but if you are hauling a lot of weight, it can add up quickly. Make sure to check your rear differential fluid level regularly and top it off as needed.


How Many Quarts of Oil Does a Rear Differential Take?

A differential is a gearbox located at the back of most vehicles that connects the driveshaft to the axles. The axle shafts transfer power from the differential to the wheels. The job of the differential is to allow each wheel to rotate at different speeds.

This is necessary when turning corners, since the inner wheel needs to rotate faster than the outer wheel. The amount of oil that a rear differential takes can vary depending on the make and model of your vehicle. Most rear differentials will take between 1 and 2 quarts of oil.

Check your owner’s manual for specific information on what type and how much oil to use in your rear differential.

What Gear Oil Does a Ram 1500 Take?

The Ram 1500 uses a variety of gear oils, depending on the model year and transmission type. For example, early model years with the 5.9L engine and 42RE automatic transmission take 7 quarts of Mercon V ATF fluid. Newer model years with the 8-speed 8HP75 automatic transmission take 8 quarts of Dexron VI ATF fluid.

And manual transmissions require either 75W90 synthetic gear oil or 80W90 conventional gear oil.

How Often Should I Change My Rear Differential Fluid Ram 1500?

If you have a Ram 1500 with a rear differential, it’s important to keep the fluid fresh. Differential fluid breaks down over time and can cause problems if it’s not changed regularly. We recommend changing your differential fluid every 30,000 miles or so.

This will help keep your rear differential in good shape and prevent any potential problems.

What Kind of Fluid Goes in a Rear Differential?

Differential fluid, also known as gear oil, is used to lubricate the gears and bearings in your car’s differential. This type of oil is thicker than engine oil and helps to reduce the friction between the moving parts in your differential.

It’s filled with a special oil that helps keep everything lubricated and running smoothly. Over time, this oil can break down and need to be replaced. When it comes time to change the fluid in your rear differential, be sure to use only Ram-approved fluids.

Ram 1500 Differential Fluid Change Cost

If you’re the owner of a Ram 1500, you’re probably aware that this truck is built to last. However, like any vehicle, it will eventually need some routine maintenance. One of the things you’ll need to do periodically is change the differential fluid.

This can be a pretty pricey repair, so it’s important to know what you’re getting into before taking your truck in for service. The cost of a differential fluid change will vary depending on a few factors, including the type of fluid being used and the location of the shop. However, you can expect to pay anywhere from $100 to $200 for this service.

That may seem like a lot, but it’s actually not too bad when you consider all that goes into changing the fluid. First, the mechanic will need to drain out all of the old fluid. Next, they’ll clean out the differential and inspect it for any damage or wear.

Once everything looks good, they’ll fill it up with fresh fluid and test drive your Ram 1500 to make sure everything is working properly. So why does all of this cost so much? Well, there’s quite a bit of labor involved in changing differential fluid.

Plus, if your mechanic has to do any additional work (like cleaning out a dirty differential), that will add to the final bill. But at the end of the day, paying for this service is worth it if it means prolonging the life of your truck!


The Dodge Ram 1500 is a great pick-up truck that can handle a lot of wear and tear. However, like all vehicles, it needs regular maintenance to keep it running smoothly. One important part of maintaining your Ram 1500 is making sure the rear differential fluid is at the correct level.

If you’re not familiar with cars, the differential is a gearbox located at the back of the vehicle that allows the wheels to rotate at different speeds (for example, when you turn a corner, the outer wheels have to rotate faster than the inner wheels). The fluid in the differential helps to keep everything lubricated and running smoothly. So how do you know if your Ram 1500’s rear differential fluid needs topping up?

There are a few signs to look out for: noise coming from the back of the car, leaking fluids, or difficulty turning corners. If you notice any of these issues, it’s time to check your fluid levels. To top up the rear differential fluid on your Ram 1500, you’ll need about 1 quart (946 ml) of 75W-140 synthetic gear oil.

You can find this oil at most auto parts stores. Once you have your oil, simply remove the fill plug on the differential and pour in new oil until it reaches the correct level. Then replace the fill plug and you’re good to go!
