The first step in figuring out what axle your truck has is to identify it. You can do this by examining the differential cover. This will show you the number of bolts and the diameter of the hub. Alternatively, you can also refer to your owner’s manual to figure out the correct axle type.
Aside from the axle number, you can also look for the axle code. Typically, this is a one or two-digit number. The axle code represents the most recent year of manufacture, followed by the month and day. For example, a 4L75 axle is made in 1975, whereas a 4L60E is made in 1989.
The two-digit axle code can also be a guide to determine what axle ratio your truck has. It will also tell you whether it has a Limited Slip Differential or not. Another good place to look is on the driver’s side door panel. This label should also include the word AXLE underneath the bar code. The two-digit axle code is also noted on the safety compliance certification label on the vehicle.
How Do I Find the Axle Ratio on My VIN Number?
The VIN (Vehicle Identification Number) is a unique seventeen-character code used to identify your vehicle. It is found on your vehicle’s title, engine or transmission labels, and on your truck’s RPO sticker, which is usually found in the glove compartment. The RPO sticker contains codes starting with F, G, and H, which will give you the axle ratio of your truck.
Your VIN contains important information about the vehicle’s history, including its speed and gear ratio. The first digits are designated as the VIN decoder (VDS), and the rest are designated as a vehicle’s serial number. This information allows you to trace your car’s history. In addition, you can check the gear ratio by counting the spikes on the rear wheels.
If you can’t find the number on your VIN, you can use a method to figure out the ratio yourself. In many cases, this involves counting the teeth on the ring gear and dividing them by the number of teeth on the pinion gear. It may also work for the front axle.
How Can I Tell What Kind of Differential I Have?
There are several ways to identify the kind of differential in your truck. First, you must know the year, make, and model of your vehicle. This is not always easy. Some vehicles have additional options that can complicate the identification process. For example, your vehicle may have an automatic transmission or be modified in some way. However, there are visual clues that you can use to identify the kind of differential in your truck.
The most common types of differentials include drop-out third-member and integrated carrier differentials. Drop-out third-member differentials have a front center section that can be removed. These differentials contain the ring and pinion gears inside a removable housing. Ford is the most common brand of a drop-out third-member differential, but you can also find it on Chevrolet, Jeep, and Toyota. Then there are integral carrier and non-detachable differentials. The first two types are commonly seen on most trucks, and the other two types are not as common.
Depending on the type of differential that your truck has, it can help you identify which parts need to be repaired or replaced. There are different types of differentials, so it is important to understand what kind your vehicle has before you buy one. An open differential, on the other hand, allows your wheels to rotate at different speeds. This type of differential is most effective when road conditions are ideal, but can be problematic when you drive on less than perfect roads. Because torque transfers through the open differential even if the wheels have zero traction, slipping tires will cause them to spin. However, repairing an open differential is easier and cheaper than fixing the other types of differentials.
How Do You Tell a Dana 44 From a 30?
Identifying the difference between a 30 and a Dana axle is not difficult. The two types are distinguished by the shape of the differential cover. The latter is round, while the former is six-sided. In addition, the front axle will have bigger pinion bearings than the latter.
The difference between a 30 and a 44 axle is largely cosmetic. The former features a cast centersection and a pressed-in axle tube. An early Dana axle is easily identified by its stop sign-shaped differential cover. The latter has four bolts instead of two.
The Dana 44 has a higher-shaft diameter. It also features a stronger axle shaft. It is also capable of handling lockers, and it’s popular among Jeep swaped-out vehicles. Despite the differences, both axles are very similar in many ways.
A Dana 44 axle has a ring gear of eight-and-a-half inches. This type of axle is used in front and rear axles of Jeep JK Wranglers. Its gear ratio is 3.21 in Sahara and Sport models. A 4.10 gear ratio is available as an option. A limited-slip differential is available in certain trim levels. You can also opt for a selectable electric locking differential. However, it is important to note that not all Dana 44 axles are created equal.
How Do I Know If I Have a Dana 60?
The Dana 60 is an automotive axle that was first used in the 1950s. It was heavier duty than the Dana 44 and was used mainly in heavy-duty trucks. It was available in full-floating or semi-floating configurations. It typically features a 30-spline axle shaft and a 9.75-inch ring gear. Its gear ratios ranged from 3.31:1 to 7.17:1.
To tell if your truck has a Dana 60 axle, you must first remove the axle from the vehicle. Next, place it on a benchtop or sawhorses. Once you have removed the axle, you must loosen the drive pinion nut. Make sure to set the parking brake before attempting to loosen the nut. You’ll also need a long breaker bar and a 1-5/16″ socket.
If you have a Dana 60 in your truck, the axle’s gear ratio is 3.54:1. This means that the axle is capable of handling high torque. In addition, it is capable of handling high horsepower drivetrains.
What Does the 8Th Digit in a VIN Number Mean?
A VIN number contains a lot of information about your vehicle. The first part of the VIN is called the Vehicle Descriptor Section, and it focuses on the vehicle’s model, body style, engine, transmission, and restraint system. The second part of the VIN contains information about the manufacturer. The ninth digit is a check digit, and it’s used to check for fraudulent VINs. Finally, the tenth and nineteenth digits indicate the YEAR and MONTH of manufacture.
The third digit of a VIN number is usually the name of a division of a larger manufacturer, such as General Motors. For example, if the VIN number started with “1GC”, the “G” is for General Motors, and “C” is for Chevrolet. The fourth and fifth digits are called the “Attributes” of the VIN, and they tell you important details about the vehicle.
The 10th digit is the model year, which is mandatory in all US vehicles. During this period, the VIN characters are repeated, although the I, O, Q, and Z are excluded. This can give you a clue about the model year, especially if the 7th digit is alpha. If the eighth digit is the same as the first, then the vehicle is more recent than 10 years old.
How Do I Identify My Axle?
A truck axle is the central shaft for the rotating wheel and gear. Most trucks have a single axle or a tandem axle. However, some trucks have three axles, called tridems. If you’re wondering how to identify your truck axle, you can use the information in the documentation included with your truck.
Your truck’s axle may have an RPO code, or a BOM stamp, which identifies the model and equipment of your truck. You can also read the code on the Service Parts Identification sticker, usually found in the glove box compartment, next to the spare tire. The sticker will contain a QR code that will tell you which axle is what. The code will also tell you what kind of axle it is.
The axle’s identification tag has a number of codes, including the axle ratio, ring gear diameter, and date of manufacture. These codes will vary from year to year, so you need to check your truck’s tag carefully.
How Do I Identify My GM Differential?
Identifying a differential can be challenging. The first step in identifying a differential is to know its make and model. Then look for tags or stamps on the axle. A GM vehicle’s axle tag will include the RPO code. Ford vehicles have identification tags that are usually located on the carrier cover bolt. These tags will usually include information such as the ring gear size, gear ratio, and differential type.
GM vehicles have stamped numbers on the axle tubes of the differential housing. These are usually 7 or 8-digit ident numbers that are usually accompanied by a manufacture date. If you’re unsure of the differential’s type or manufacturer, you can identify it by its size and the RPO code.
Different GM differentials have different shapes and sizes. The 8.5-inch differential, for example, has a round cover with a bulge for the ring gear. It also features two lugs on the lower case at the five and seven o’clock position. The 8.2-inch differential, on the other hand, does not have these lugs. Another identifying feature is the length of the axle tube and its gasket.
