How much fluid does a 2017 Subaru Impreza rear differential take?
As a car owner, knowing the specifications of your vehicle is crucial for proper maintenance and longevity. One important aspect of vehicle maintenance is understanding the fluid capacities of various components, including the rear differential. In this article, we will explore how much fluid a 2017 Subaru Impreza rear differential requires and why it's essential to keep it properly filled.
Fluid Capacity of the Rear Differential
The rear differential of the 2017 Subaru Impreza typically requires approximately 1.1 quarts (or 1.0 liters) of differential fluid. This amount can vary slightly depending on the specific model and whether it has a limited-slip differential or not. It's always a good practice to consult your owner's manual for the most accurate specifications.
Importance of Proper Fluid Levels
Maintaining the correct fluid level in your rear differential is vital for several reasons:
- Lubrication: The differential fluid lubricates the gears and bearings, reducing friction and preventing wear.
- Heat Dissipation: Proper fluid levels help dissipate heat generated during operation, which can prevent overheating and potential damage.
- Performance: Adequate fluid levels ensure smooth operation of the differential, contributing to better handling and performance of the vehicle.
- Longevity: Regularly checking and maintaining fluid levels can extend the life of your differential and save you from costly repairs.
Checking and Changing the Differential Fluid
To ensure your rear differential is functioning optimally, it's essential to check the fluid level regularly. Here are some steps to follow:
- Locate the differential fill plug, usually found on the side of the differential housing.
- Remove the fill plug and check the fluid level. The fluid should be just below the fill hole.
- If the fluid is low, add the appropriate differential fluid until it reaches the correct level.
- Consider changing the differential fluid every 30,000 to 60,000 miles, or as recommended in your owner's manual.
By keeping an eye on your Subaru Impreza's rear differential fluid levels, you can ensure a smoother ride and enhance the overall performance of your vehicle. Regular maintenance is key to avoiding more significant issues down the road.
Frequently Asked Questions
What happens if you never change differential fluid?
Most differentials need a fluid change at about 50,000 miles. If left too long or if the fluid starts to run low, the differential will become noisy and can eventually fail. If that happens, the gears can seize, locking up the rear wheels and potentially causing a lot of damage or even an accident.
How often should I change my rear differential fluid?
Differential Fluid usually lasts longer than most other fluids. The life of differential fluid is variable but a major difference between for example oil and differential fluid, is differential fluid usually is not filtered. Usually, differential fluid is changed after every 30k to 60k miles driven.
How many quarts are in a rear diff?
1 quart for the replacement. But if you plan on squeezing the quart bottle to refill diff after draining, purchase 2 quarts.
How often should I change the differential fluid on my Subaru Impreza?
When Should Differential Fluid Be Changed? Fortunately, differential fluid doesn't need to be changed as often as the oil in your engine, but we do recommend that you get your differential fluid replaced every 15,000 miles or so.
How much oil does a 2017 Subaru Impreza differential take?
You'll need a pump to fill both differentials. Three quarts of 75w90 is sufficient.
How often should I replace rear differential fluid?
every 30k to 60k miles driven

How do I know if my rear differential fluid needs replacing?
Hearing a whirring, whining or howling sound, which may indicate the parts, clutches, gears and diff are not properly lubricated through insufficient clean oil. Feeling unusual vibrations, like a chatter, which is caused by a number of mechanical issues, including needing diff oil.
How much fluid does a 2015 Subaru Legacy differential hold?
Differential Lubricant: Front
Capacity: Front 3 pints. Notes: (1) SAE 75W-90 is preferred.
How much fluid goes in the rear differential?
towing capacity using a rear differential that holds between 3.3 and 3.5 quarts of fluid. This means less lubrication is responsible for protecting gears against increased heat and stress.
When should I change my Subaru differential oil?
Having your Subaru's differential fluid drained and replaced as often as every 30,000 miles is important to keeping your vehicle running in top condition.
