In addition to providing access for changing gear lube, differential covers help dissipate heat that can damage differentials, and they protect gears from contaminants like dirt and water, as well as rocks and other large obstacles encountered when off-roading.
Is a 14 bolt A 1 ton axle?
The 14-Bolt Is The Ford 9-Inch Of 1-Ton Trucks
Every diesel-powered pickup sold in the United States for the last 10 years has a full-floating rear axle.
Are all 14 bolt axles the same?
Over the years, there have been millions of 14 bolt axles produced. And, of course, they weren’t all the same. GM 14 bolt axles were available in semi-float and full-float versions, and there are two types of hubs found on 14 bolt axles. Also, two different types of drums were used.
What is a 14 bolt full floater?
You can spot a full-float rear axle by looking at the wheels. Full-float axles have a tell-tale “axle end” that sticks out from the wheel surface. This is because the wheel hub on a full-float 14-bolt axle will stick out beyond the wheel mounting surface anywhere from about two to four inches.

What year is a 14 bolt A full floater?
In 1973, GM introduced the 14 bolt axle to the world. At that time, it was a “full-float” axle only, with stud-mounted brake drums. The axle was designed for use in heavy duty trucks.
How strong is a Chevy 14 bolt rear end?
GM’s Strong & Plentiful Axle
First appearing in 1973, the 14-bolt is one of the most used rear axles in the General Motors stable. Found under ¾- and 1-ton GM trucks, vans and SUVs, the 14-bolt received a max torque rating of 6,242 pounds.
What does full float mean?
For a full-floating system, the axle shaft only serves to transmit the rotational torque from the differential out to the wheel. It does not carry the weight of the vehicle as a semi-floater does. On a full floater, a spindle is attached to the outer end of the axle housing.
What does full floater rear end mean?
In a full-floating axle, the axle is not attached to the axlehousing at all; it is allowed to “float” inside the axlehousing. A tubular shaft is mounted to the end of the housing and acts like your front spindle, only it is hollow to allow the axle to meet up with the wheel assembly.
How can you tell the difference between a semi floating and full floating axle?
What’s the difference between full floating and semi floating?
A semi-float axle rides on an outer bearing, thus supporting the weight of the vehicle. In semi-float applications the wheel is bolted directly to the axle. A full-float axle is a housing type in which the axle does not carry the load of the vehicle and does not have the wheel bolt directly to it.
Can a front axle be full float?
Any drive axle must be capable of performing two functions: Support the weight of the vehicle safely and transmit power to the wheels for propulsion. By design, all steering (front) drive axles are full-floating, but rear drive axles may be semi-floating or full-floating.
What is a dead axle?
noun. : an axle that carries a road wheel but has no provision for driving it.
What are the three types of vehicle axle?

Why do trucks lift axles?
By lifting the axle, the tires are preserved and usable for a longer amount of time. Lifting the axle also prevents scrubbing in non-steer configurations, reducing uneven tire wear and the chance of a blow-out. The lift axle is mounted on a truck, a trailer, or sometimes both.
What is the end of an axle called?
Commonly examples include Ford 9-inch and Toyota axles. End Forging: Often called an Inner C, the end forging is the component on the end of a front axle housing that the knuckle bolts to with either ball joints or kingpins.
How do I know what rear end I have?
Stamped Number on the Axle
To figure out exactly what axle you have, you can look for the Dana stamped bill of materials number. This stamped number can usually be found on the righthand side or on the longer axletube on the same side of the tube as the differential cover, facing the rear of the truck.
How can I tell what gear ratio I have without pulling cover?
With the transmission in neutral, rotate the rear driveshaft by hand.Count the number of driveshaft revolutions required for one revolution of the tire. If the driveshaft turns approximately 3-1/2 times, you have a 3.54 ratio, etc.
How do I know my diff size?
How do I know my differential size?
The most accurate differential identification is provided by the bottom line of the tag number or axle tube stamp. Differential tags can easily be used to identify Dana and Ford differentials.
What gear ratio is best for towing?
Performance: Looking again at the ratios used above, the higher 3.55 ratio indicates faster acceleration whether the truck’s empty or loaded. The higher the ratio, the more revolutions per minute. Towing: For pickup trucks released after 2010, the best axle ratio for towing falls somewhere between 3.55 and 3.73.
