Rear Differential Fluid for 2006 Ford Ranger
The rear differential fluid for a 2006 Ford Ranger is 80W-90 rear axle lubricant. If the vehicle has a Traction-Lok limited slip, it is recommended to add Ford friction modifier to prevent chattering. Some synthetic makers suggest that the modifier is not needed with their oil. When changing the fluid, the process involves pulling off the differential cover to drain the oil, cleaning and resealing the cover joint, and adding fluid up to 1/4″ below the filler hole.
It’s important to note that the rear differential fluid doesn’t need to be changed as often as some other fluids, like engine oil, but it does degrade over time. Ford recommends changing the rear differential fluid every 30,000 to 50,000 miles, with a closer aim to the 30,000-mile mark for the Ranger specifically.

What kind of rear differential fluid does a 2003 Ford Ranger take?
Location: Rear. Viscosity: SAE 75W-140. Oil Base: Synthetic. Oil Type: API GL-5.
Does it matter what differential fluid you use?
The best way to determine which differential fluid is correct for your application is to reference your vehicles owner’s manual. Using the appendix, locate the section under fluids, transmission fluid, transfer case fluid, or lubrication.
What happens if you use the wrong differential fluid?
They found that whoever replaced the oil in the differential with the wrong viscosity was directly responsible for the damage caused to the front differential assembly and the four-wheel-drive (clutch) assembly.
Is there a big difference between 75W90 and 80w90?
SAE 75W-90 maintains a more consistent thickness, or viscosity, across a wide temperature range. It’s thicker when exposed to high heat and thinner under colder, wintry conditions than 80W-90.
What kind of fluid goes in a 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 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. Therefore, engine oil should never be used in place of gear oil.
What kind of rear differential fluid does a 2005 Ford Ranger take?
Ford Ranger 2005, SAE 80W-90 API GL-5 Limited Slip Differential Fluid by Sta-Lube®. Limited Slip. This product is made of high-quality components to meet and exceed strict quality requirements.
What is the difference between 75W90 and 75W140?
So, the difference between “75W90” and “75W140” is that at operating temperature, the 75W140 will be considerably thicker than the 75W90 but at room temperature they will be about the same viscosity.
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. Therefore, engine oil should never be used in place of gear oil.
