The Toyota Tundra is a full-size pickup truck renowned for its durability, off-road capability, and reliable performance.
Proper maintenance of the front differential, especially ensuring it has the correct oil capacity and type, is essential for preventing wear, overheating, and costly repairs.
Toyota Tundra Front Differential Oil Capacity
Toyota Tundra front differential oil capacity is generally around 1.3 to 1.4 liters (approximately 1.4 to 1.5 US quarts), and using the recommended 75W-90 GL-5 gear oil ensures proper lubrication, reduces wear, prevents overheating, and keeps the 4×4 system operating smoothly for both daily driving and off-road conditions.
| Model Years | Generation | Front Differential Oil Capacity (4WD) | Approx. US Quarts | Notes |
|---|---|---|---|---|
| 2000–2006 | 1st Generation | 1.1–1.2 liters | 1.2–1.3 qt | Applies to early 4WD Tundra models |
| 2007–2013 | 2nd Generation (Early) | 1.2 liters | 1.3 qt | Slight increase due to redesigned front axle |
| 2014–2019 | 2nd Generation (Facelift) | 1.2–1.3 liters | 1.3–1.4 qt | Minor variation depending on axle configuration |
| 2020–2021 | 2nd Generation (Final Years) | 1.3 liters | 1.4 qt | Updated drivetrain components |
| 2022–2024 | 3rd Generation | 1.3–1.4 liters | 1.4–1.5 qt | New platform with revised differential design |
| 2025–2026 | 3rd Generation (Current) | 1.3–1.4 liters | 1.4–1.5 qt | Capacity remains consistent with 2022 redesign |

Recommended Differential Oil
Toyota generally recommends using SAE 75W-90 GL-5 gear oil for the front differential. If your Tundra has a limited-slip differential, a special additive may be required to prevent chatter and ensure smooth operation. Using the correct oil helps:
- Reduce friction and heat
- Protect gears and bearings
- Enhance off-road and towing performance
- Extend the life of the differential
What Is the Front Differential?
The front differential is a gear assembly located on the front axle of 4×4 Toyota Tundra models. Its main role is to transfer torque from the transfer case to the front wheels, allowing them to rotate at different speeds while maintaining power during turns.
Without proper lubrication, the gears and bearings inside the differential can experience excessive friction, leading to premature wear and possible failure.

How to Change Front Differential Oil
Changing the front differential oil is a straightforward maintenance task:
- Park your Tundra on a level surface and turn off the engine.
- Remove the fill plug on the differential cover and the drain plug at the bottom.
- Allow the old oil to drain completely into a container.
- Inspect and replace the drain plug and gasket if worn.
- Refill with the recommended oil until it reaches the bottom of the fill plug hole.
- Reinstall and torque the fill plug to manufacturer specifications.
- Check for leaks and test drive to ensure smooth operation.
Signs You Need to Check Your Differential
Watch for these indicators that your front differential may need attention:
- Unusual whining or clunking noises while accelerating or turning
- Vibration from the front axle
- Leaks around the differential cover or axle seals
Timely maintenance and using high-quality synthetic oil can prevent serious damage and improve the Tundra’s overall performance, especially for towing, off-roading, and heavy-duty use.
Final words
Maintaining the Toyota Tundra front differential oil at the correct capacity is crucial for the truck’s durability and performance. Most Tundras require 1.3 to 1.4 liters of 75W-90 GL-5 gear oil, with limited-slip differentials possibly needing an additive.
Regular inspection, proper oil selection, and timely changes help extend the life of the differential, reduce noise, and ensure smooth 4×4 operation. Using high-quality synthetic oils like Red Line, Royal Purple, or Mobil 1 provides superior protection and keeps your Tundra ready for any road or off-road challenge.
