When should you change the differential fluid on a Toyota Highlander?
The differential fluid in a Toyota Highlander should be changed at regular intervals to ensure the proper functioning and longevity of the vehicle's drivetrain. The recommended frequency for changing the differential fluid can vary depending on the driving conditions and the manufacturer's guidelines.
Recommended Differential Fluid Change Intervals for Toyota Highlander
According to Toyota's maintenance schedule, the differential fluid in a Highlander should be changed every 30,000 to 60,000 miles, or every 24 to 48 months, whichever comes first. This recommendation applies to both the front and rear differentials, if the vehicle is equipped with all-wheel drive (AWD).
However, it's important to note that the actual interval may need to be adjusted based on the vehicle's usage and driving conditions. For example, if the Highlander is frequently used for towing, hauling heavy loads, or driven in severe conditions such as off-road or in extreme temperatures, the differential fluid may need to be changed more frequently.
