What differential does a 2014 F150 have?

What years did Ford use the 9 inch rear end?

The Ford 9-inch rear end, so named because of its 9-inch ring gear diameter, was manufactured from 1957 to 1987 by the Ford Motor Company and installed in some intermediate and most full-size Ford, Lincoln, and Mercury passenger cars, F-Series ½-ton trucks, and Econoline vans.

When did Ford stop using the 9 inch rear end?

The Ford 9-inch is an automobile axle manufactured by Ford Motor Company. It is known as one of the most popular axles in automotive history. It was introduced in 1957 model year cars and ended production in 1986, having been phased out in favor of the Ford 8.8 inch axle.

What gear ratio is a Ford 9-inch rear end?

The Ford 9 inch rear end also has the widest variety of ratios on the market, Particularly in the 3.0:1 to 5.0:1 range. Ford improved tooth contact of the Ford 9 inch gears by locating its pinion gear lower on the ring gear. This strengthens the whole rear end assembly.

How can you tell the difference between 8.8 and 9.75 rear end?

On the passenger’s side upper and lower corners, there’s two semi-circular divots that can easily be seen when looking at the cover from straight on. While the Super 8.8’s cover has a bulge for the ring gear, it’s not anywhere near as pronounced as the 9.75’s.

How do I find out what gear ratio My Ford rear end has?

Locate the two-digit code in the box labeled “AXLE,” which is just below the bar code. Match the code on the label to the corresponding rear axle ratio. The code “15” means your truck is equipped with a 3.15 axle ratio; “27” refers to a 3.31 ratio; “19” to a 3.55 ratio; and “26” to a 3.73 rear axle ratio.

How many splines is the Ford 9.75 rear end?

Axle Spline Count: 34.

How do I know if I have 28 or 31 spline axles?

The obvious differences in 28 and 31 spline axles will be the number of splines! When you count the number of teeth (splines) on each axle, you can find out which option you have. 31 Spline Axles also tend to be larger in diameter to accommodate the increased amount of splines.

How do I know if my Ford 9-inch is a limited slip?

To recognize a locking or limited slip 9″ differential, look for a metal tag on one of the bolts that holds the center section to the housing. There is a gear ratio stamped on the tag. For example: The tag will say: 350 for 3.50:1 ring and pinion gear ratio.

How much horsepower can 35 spline axles handle?

S/T 35-Spline Axles (up to 800 hp1) For street/strip applications, the S/T axles feature a larger 1.50”-diameter 35-spline end that is better suited for the extreme levels of torque during launches.

What is the difference between 35 and 40-spline axles?

The distance between the centerline of adjacent splines remains constant, so as the diameter of the shaft increases, so does the number of splines. As an example, a 35-spline axle has a major diameter of 1.500-inches while a 40-spline axle measures 1.708-inches in diameter.

Why are more splines better?

Higher spline counts gives the axle more surface to transfer the load of the torque from the differential. There is also the side advantage that an axle with more splines will also be physically bigger. At least in most modern axles that use similarly sized spline teeth.

How much torque can 31-spline axles handle?

A 30-spline axle is rated at 6,200 lb-ft, a 31-spline at 7,000, a 33-spline at 8,200, a 35-spline at 9,600, and a 40-spline at 12,000.

Should axle splines be greased?

Do not use grease, anti-seize compound or other lubricants when mating the CV axle shaft to the wheel hub assembly. Clean and remove all corrosion, rust, burrs and any other debris from the CV axle spline end, wheel hub assembly and steering knuckle.

How do I know my axle spline count?
