Rear Toyota Tundra Differential Fluid Specification Guide

2nd Generation XK50 Toyota Tundra (2007-2021)

The following rear differential fluid information applies to the 2007 to 2021 Toyota Tundra XK50 or 2nd generation models. The Toyota Tundra models started recommending 75W-85 GL-5 gear oil for use in the rear differentials in the model year 2007. The gear oil part number is 08885-02506.

Some may still choose to use alternative viscosity gear oils in the Toyota Tundra rear differential even though a 75W-85 GL-5 gear oil is specified for the 2007-2021 Toyota Tundra rear differential. We always suggest using differential gear oil in accordance with the vehicle manufacturer's recommendations as noted in service and owner's manuals. This will ensure the best rear differential function. Using the suggested gear oil viscosity and spec formulation will ensure the correct rear differential lubricating characteristics are met for the intended differential designed functions. Also, you can expect to achieve the best performance results and long-term reliability for all internal rear differential components.

Gear Oil Specifications & Part Numbers Used in 2nd Gen XK50 Toyota Tundra Rear Differentials

Popular 75W85 GL5 gear oils typically use general formulations for various applications. In some cases, these generic inexpensive gear oils can offer low lubricating performance levels and essential characteristics requiring more frequent rear differential fluid changes. This is due to lower-quality base oils that break down and lubricating additives that become prematurely depleted. We recommend using a 75W85 GL5 gear oil for these Toyota Tundra XK50 rear differential applications based on high-quality synthetics. See our online catalog to learn more about the performance and heavy-duty benefits of the Toyota Tundra rear differential fluid.

2nd Generation XK50 Toyota Tundra (2007-2021)

The following front differential fluid information applies to the 2007 to 2021 Toyota Tundra XK50 models. The Toyota Tundra 4WD models started recommending 75W-85 GL-5 gear oil for use in the front differentials in the model year 2007. The gear oil part number is 08885-02506.

The Toyota 75W-85 gear oil also offers a better flow of gear oil lubrication to key areas of the front differential, especially during initial differential 4WD rotation and engagement. It also supplies better cold climate lubrication while still maintaining the necessary high load shear stability.

Some may still choose to use alternative front differential gear oil viscosity options or general multi-application gear oils even though a high quality 75W-85 gear oil is specified. We always suggest using a fluid in accordance with the vehicle manufacturer's recommendations as noted in service and owner's manuals. Using the suggested gear oil SAE 75W-85 viscosity with GL-5 specification formulation will ensure intended differential designed functions are achieved with the best performance results. Using the correct viscosity will also provide the best possible lubricating characteristics for the internal front differential components and will ensure long term reliability is met. The newer Toyota Tundra 75W-85 GL-5 front differential gear oil contains a more sophisticated additive formulation using higher quality additives and more advanced fully synthetic base oils when compared to many popular 75W-90 gear oils. The high-quality level of the 75W-85 GL-5 front differential fluid formulation achieves the benefits of instantaneous lubrication flow to internal components in cold weather while maintaining excellent shear stability in high load, high temperature driving conditions.

Gear Oil Specifications & Part Numbers Used in 2nd Gen XK50 Toyota Tundra Front Differentials

When choosing a 75W-85 GL-5 gear oil for the Toyota Tundra front differential we suggest heavy-duty gear oils based on high quality fully synthetic PAO (Polyalphaolefin) oils. See our product descriptions to learn more about the performance and heavy-duty benefits of the fully synthetic Eurol or Ravenol 75W-85 GL-5 gear oils.

Toyota Tundra Differential Fluid Change Intervals

When should you change your Toyota Tundra front and rear differential fluids? While it's always best to follow the manufacturers' recommendations, changing the fluid from around 50,000 miles to 60,000 miles should be acceptable under normal driving conditions. However, depending on your driving style the differential gear oils could be changed more frequently. For example, if the vehicle experiences aggressive driving, full-time/consistent 4WD engagement, off-roading, and frequent trailer pulling, you should service the differential fluids more frequently and as early as every 30,000 miles. Also, if using a cheaper, non-synthetic brand of fluid, the differential fluid will need to be changed more often. Following the recommended Toyota Tundra rear differential fluid change intervals and the recommendations noted here can eliminate and minimize mechanical issues and costly differential repairs.


Why Should Toyota Tundra Differential Fluid Be Changed?

Your differential contains numerous moving internal components, including bearings, pinion gears, and crown gears. These parts depend entirely on the lubrication film strength of the differential fluid for protection and longevity. During normal everyday driving, the differential fluid is subjected to high shear loads and various heat cycles. Over time, regular driving conditions can degrade the fluid, diminishing its lubricating properties and film strength. Running old differential fluid and gear oils can lead to wear on the differential bearings, pinion gears, and potentially cause other failures. To prevent differential failure, it is important to regularly change the Tundra differential fluid. Incorporating rear differential fluid changes into your routine maintenance will significantly extend the life of the rear differential, reduce driveline noises, chatter, and vibrations due to wear, and ensure the differential bearings and gears receive reliable, clean lubrication.
