What size axle is a fj60?
The Toyota Land Cruiser FJ60 typically uses solid front and rear axles, with a front axle commonly listed as Dana 44 and a rear axle as Dana 60 in the stock US-market configuration. Exact axle models can vary by year and international market, so it's wise to verify your specific vehicle.
Axle configuration and stock sizes
The following outlines the stock setup most FJ60s shipped during its production run. This information helps with maintenance, parts compatibility, and planning upgrades.
- Front axle: Dana 44 (solid front axle used with the FJ60’s leaf-spring suspension).
- Rear axle: Dana 60 (solid rear axle, also leaf-spring, used on the FJ60).
In practice, many FJ60 owners will find this front/rear pairing to be the most common configuration, though regional variations and specific build options can differ.
Variations by year and market
While the above pairing is the typical stock setup, some export models and certain production years employed alternative front axles or different gear ratios. Always verify the exact axle by inspecting the differential housings, stamping, or axle codes on your vehicle.
- Common US-market configuration (1980–1989): Front Dana 44, Rear Dana 60.
- Some international or early-production examples may use different front axles or optional equipment; confirm with vehicle documentation or by inspecting the axle castings and tags.
Conclusion: The standard FJ60 axle combination is front Dana 44 and rear Dana 60, but market-specific variations do exist. Verifying the exact axle on your particular vehicle is always recommended before ordering parts or planning swaps.
Notes for enthusiasts and builders
For those considering upgrades or axle swaps, here are practical considerations to keep in mind. Verification of your exact axle type is essential before purchasing parts or attempting modifications.
- Verify axle codes by checking the differential cover or axle housing markings to avoid misidentification.
- When planning gear ratio changes or gearing for off-road use, ensure compatibility with both axles and the transfer case.
- Brake, hub, and spline compatibility can vary between Dana 44 and Dana 60 components; plan calipers, rotors, and wheel hubs accordingly.
Always cross-check with a trusted source (factory manuals, VIN-specific sheets, or a knowledgeable technician) to confirm the exact axle configuration on your FJ60.
Summary
In most stock FJ60 models, the axle pairing is front Dana 44 and rear Dana 60, a setup favored for durability and off-road capability. There are year- and market-specific variations, so verifying the precise axle type on your vehicle is important for maintenance, parts sourcing, and potential upgrades. Short answer: yes—the common stock configuration is Dana 44 front and Dana 60 rear, with variations possible depending on market and production year.
How do I know if I have 28 or 31 spline axles?
Inspect the center of the axle end: Look for a depression or marking in the center of the axle hub. 28-spline: You will likely see a rectangular depression. 31-spline: You will likely see a small round depression in the center, with two additional small holes or depressions located outside of it.
Is a Dana 60 wider than a Dana 44?
Although the Dana 44 and Dana 60 differential covers look similar, their sizes are significantly different. The Dana 44 differential cover will measure about 9 1/2 inches wide and 10 1/2 inches tall, while the Dana 60 differential cover will measure about 11 1/4 inches wide and 12 inches tall.
What size is the Dana 60 front axle?
A modern Dana 60 front axle comes stuffed with much stronger 1.5-inch-diameter, 35-spline axleshafts (center), which can safely handle 37-to-44-inch tires. Aggressive drivers can take their Dana 60 a step further with aftermarket 1.70-inch-diameter, 40-spline axleshafts (left).
Is a Dana 60 a 1 ton axle?
Yes, a Dana 60 is considered a 1-ton axle, particularly when it is the front axle found in 1-ton trucks. However, a Dana 60 rear axle is typically rated as a 3/4-ton axle, and while the Dana 60 is a heavy-duty axle, the 1-ton designation is specific to its application in 1-ton trucks.

- Front axles: The Dana 60 front axle is the most common 1-ton axle found in 1-ton trucks and is also very popular for swaps into other vehicles because of its strength.
- Rear axles: A Dana 60 rear axle is generally rated as a 3/4-ton axle.
- Heavy-duty components: The 1-ton Dana 60 features larger components than its 1/2-ton counterparts, including a larger ring and pinion, axle shafts, and a stronger housing, which makes it more durable for heavy loads and large tires.
- Usage: While Dana 60s were originally used in 1-ton trucks, they have become a popular upgrade for off-roading enthusiasts due to their strength and durability.
