Your vehicle’s differential system is a gearbox between the drive wheels that allows wheels to turn at independent speeds and assists your car in turning. All-wheel drive Subarus have both front and rear differentials. The fluid in the differential system breaks down over time and will eventually need to be replaced.
How do I know if I need differential service?
Check your vehicle’s recommended maintenance schedule
If you hear a rumbling sound when driving above 15 mph
If you hear a high pitched sound while accelerating
If your vehicle makes a banging sound around corners.
If any of the above are true for your Subaru, it may be time for front or rear differential service. Ready to make an appointment? Schedule an appointment today
