What kind of oil does a Ford Ranger rear diff take?
The Ford Ranger rear differential typically takes a 75W-90 gear oil. This is a common type of gear lubricant used in many rear differential and transfer case applications for light-duty trucks and SUVs.
Detailed Explanation
The Ford Ranger is a popular mid-size pickup truck that has been in production since the 1980s. Like most trucks, the Ranger is equipped with a rear differential, which is responsible for transferring power from the driveline to the rear wheels and allowing them to rotate at different speeds when turning.
The rear differential in a Ford Ranger requires a specific type of gear oil to function properly and ensure long component life. The recommended oil is typically a 75W-90 gear lubricant, which is a multi-grade, synthetic-blend oil designed for use in automotive differentials and transfer cases.
Key Characteristics of 75W-90 Gear Oil
- Viscosity: The "75W" designation indicates the oil's low-temperature viscosity, allowing it to flow easily in cold weather. The "90" refers to the oil's high-temperature viscosity, providing adequate lubrication at normal operating temperatures.
- Composition: 75W-90 gear oil is a synthetic-blend formulation, combining the benefits of both conventional and synthetic base oils. This provides improved thermal stability, oxidation resistance, and cold-weather performance compared to conventional gear oils.
- Applications: In addition to Ford Ranger rear differentials, 75W-90 gear oil is commonly used in other light-duty truck and SUV differentials, as well as manual transmissions and transfer cases that specify this type of lubricant.
It's important to use the recommended 75W-90 gear oil in the Ford Ranger's rear differential to ensure proper lubrication, cooling, and protection of the gears and bearings. Using the wrong oil type or viscosity can lead to premature wear, increased friction, and potential differential failure.
What happens if you never change differential fluid?
Most differentials need a fluid change at about 50,000 miles. If left too long or if the fluid starts to run low, the differential will become noisy and can eventually fail. If that happens, the gears can seize, locking up the rear wheels and potentially causing a lot of damage or even an accident.
What kind of oil does a 2017 Ford Ranger diff take?
Nulon Limited Slip Differential Oil 80W-90 1Ltr - LSD80W90-1E.
Is gear oil the same as rear differential fluid?
The differential fluid, also known as gear oil, is specifically formulated to lubricate and protect the gears and bearings within the differential housing. On the other hand, transmission fluid is responsible for lubricating and cooling the intricate components of your vehicle's transmission system.
How often do you change the differential fluid on a Ford Ranger?
every 30k to 60k miles driven
Differential Fluid usually lasts longer than most other fluids. The life of differential fluid is variable but a major difference between for example oil and differential fluid, is differential fluid usually is not filtered. Usually, differential fluid is changed after every 30k to 60k miles driven.
What kind of rear differential fluid does a 2019 Ford Ranger take?
80W-90 fluid
The owner's manual for the 2019 model year states 80W-90 fluid and 3.04 pints for a locking axle.
What oil is in a Ford Ranger differential?
Ford Ranger Front Differential Oil 75W-90 (1 Litre) ->2022.
What kind of oil goes in the rear differential?
There are two basic types of differential fluid: Mineral oil, which is a natural, crude oil-based fluid. Synthetic differential fluid, which is created with chemicals and can be fine-tuned for optimal performance.
What kind of fluid does a Ford rear differential take?
Rear Axle Oil SAE 80W-90 C2.
What fluid should never be used in a rear differential?
Never, under any circumstances, put engine oil in your differential. This will result in devastating damages to your engine. Engine oil is much different than gear oil, mostly it cannot withstand high pressure.
How often does Ford recommend changing differential fluid?
In our example above, Ford recommends changing differential fluid every 150,000 miles in normal service. But they drop the change interval significantly – to every 30,000 miles – when towing frequently at wide-open throttle and driving at temps above 70ºF.
