What kind of fluid does a Ford rear differential take?
The Ford rear differential typically takes a specialized gear oil or differential fluid. The specific type and amount of fluid required can vary depending on the model and year of the Ford vehicle.
Ford Rear Differential Fluid Requirements
Ford rear differentials are designed to use a specific type of gear oil or differential fluid to lubricate and protect the gears and bearings. The recommended fluid can vary based on the vehicle model, year, and differential type. Generally, Ford recommends using a high-quality, SAE 75W-90 or 80W-90 gear oil that meets the Ford specification for the particular vehicle.
Some common Ford rear differential fluid specifications include:
- Ford Motorcraft SAE 75W-90 Premium Synthetic Rear Axle Lubricant
- Ford Motorcraft SAE 80W-90 Premium Conventional Rear Axle Lubricant
- Ford Motorcraft SAE 75W-140 Synthetic Rear Axle Lubricant
The amount of fluid required can range from around 1.5 to 3 quarts, depending on the differential size and vehicle model. It's important to consult the owner's manual or Ford service information to determine the exact fluid type and fill capacity for a specific Ford vehicle.
Importance of Proper Rear Differential Fluid
Using the correct fluid is crucial for the proper operation and longevity of the Ford rear differential. The gear oil lubricates the gears and bearings, helps dissipate heat, and prevents wear and damage. Using the wrong fluid or failing to change it at the recommended intervals can lead to differential failure, which can be an expensive repair.
When servicing the rear differential, it's best to have the fluid changed by a qualified mechanic who can properly drain the old fluid, inspect the components, and refill with the recommended Ford-approved gear oil.
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.
Can you use 75w90 instead of 75W85 Ford?
Our answer: Yes, 75W-85 gear oil can most definitely be replaced by 75W-90.
What kind of gear oil does Ford use?
75W85 viscosity gear oils for F-150 front and rear differential gear oil XY-75W85-QL, WSS-M2C942-A.
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. The use of 75W-90 gear oil is recognized by OEMs as a contributor to overall fuel economy.
What fluid would most likely go in a rear differential?
The fluid used in a differential is typically referred to as gear oil, which has thicker properties than regular engine oils. Viscosity Grades: The '75' in '75w' stands for the oil's viscosity rating.
How much oil does a f150 rear diff hold?
2.74 quarts
(Rear differential capacity 2.6 liters or 2.74 quarts).
Is gear oil the same as rear differential fluid?
Differential fluid, also known as gear oil, is designed for vehicles with manual gearboxes controlled by a clutch, pedal, and stick shift. Manual gearboxes are designed as a two-shaft system, and although this design gives manual cars more oomph, it produces an enormous amount of heat and friction.
What type of ATF does Ford use?
MERCON® transmission fluids undergo extensive testing, both in the lab and in real-world conditions, to ensure they provide optimum performance and durability. MERCON® fluids are the only fluids approved by Ford Motor Company for their recommended application.
Which is thicker 75W90 or 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 I put in my rear differential?
It's just a standard GL-5 gear lube that you need. 99.999% of the GL-5 gear lubes you'll find on the store shelves already contain the friction modifier additive.
