One of the first things you need to know about your truck is the type of rear end. If your truck is an GM, you can identify the rear end by looking at the bottom line of the tag. For a Dodge or other make, you can check the axle tube stamp. The serial number and axle size are also listed on the tag.
Next, you need to find the rear end ratio. If you have a Chevy, you can look at the rear end ratio. For example, if your truck is an ’04 model,’ it has a rear end ratio of 7.5-inch. If your truck is a ’05 or ’06 model,’ it has an 8.5-inch rear end.
How Do I Know What Differential My Truck Has?
There are a few ways to find out what differential your truck has. First, check the tag number. This can be found on the bottom line of the tag number, or it may be stamped on the axle. On GM vehicles, look for the RPO code on the tag. For Fords, the identification tag is located on the carrier cover bolt. It will list the axle’s Ring Gear Size, Gear Ratio, and the type of differential it has.
You can also check the pinion nut size. The pinion nut size is a good indicator of the type of differential your truck has. If you do not have this information, you can take a look at the differential cover. If it’s a pinion nut, you can also use a test fitting socket to determine the size.
The differential gear ratio is the final gearing change from the transmission to the wheels. The ratio is a number, and a higher ratio means more torque goes to the road. Although this may seem counterintuitive, it is important to know what you’re working with and how it relates to your project.
How Do I Identify My GM Rear Differential?
If you’re not able to find an ID tag, you can try to identify your GM rear differential by looking at the shape of the axle cover and the diameter of the ring gear. You can also check for differences in the number of axle tube stamps and the number of bolts on the differential cover. In addition, you can also find out the difference between dropout and integral differential designs by looking at the center section of the differential.
First, you’ll have to identify whether your vehicle has an open or posi rear differential. Look for stickers or metal tags on the differential cover. To make sure, turn the rear wheel in Neutral. If it doesn’t spin, it’s an open differential. If your car has an open differential, it may be difficult to identify.
After you identify the type of rear end, the next step is to determine the type of axle housing. The 10-bolt rear differentials have a casting number that is located on the driver’s side of the axle tube. This is usually located about three inches from the center of the axle tube. Aside from the casting number, you can also check the gears on your GM differential by counting the number of teeth on each gear. If you find a discrepancy between the ring gear’s number and the pinion gear’s, you can then check out the ratio of each gear.
What Type of Rear Differential Do I Have?
To identify the type of rear differential in your truck, you must look at the axle tube stamp and tag number. If both are intact, it should be fairly easy to identify the differential. The different cover designs and the number of ring gear bolts also provide helpful hints. If both are missing, it’s probably best to find a used rear axle.
The first type is an open differential, which allows for some variation in wheel speed and slip. While it works best on optimal road conditions, it is prone to breakdowns on less-than-ideal roads. When the driver hits a bump, the wheel that loses traction will spin. The good news is that an open differential is relatively cheap to repair compared to other types of differentials.
Depending on your vehicle’s make and model, you can either buy a new differential or replace it. You can buy an empty 8.5-inch housing for under $150 or a complete rear axle assembly for around $350-$500. If you’re willing to spend more money, you can also upgrade your vehicle’s rear differential by using a 12 bolt Positraction carrier. These can be purchased from differential specialists. You can also install a manual locker for improved off-road ability.
How Can I Tell What Rear End My Silverado Has?
First, you need to know what size of rear end your Silverado has. In addition to the overall size of the rear end, the gasket shape also helps you identify the type of rear end you have. A chart of the different gasket shapes is available on Ring & Pinion’s web page.
The rear end of a Chevy truck consists of the rear axle and differential gears. These parts are housed in a cast iron or aluminum casing and contribute to applying torque to the wheels. If you’re not sure which rear end your Silverado has, you can check the serial number and size of the rear end from its tag.
Once you know the size, you can figure out what kind of differential your Silverado has. There are three types of rear ends. These are Dana 60, 7.5-inch Dana 60, and 12-bolt. Look for the inspection cover bolts on the rear end housing. Once you remove the inspection cover, you’ll be able to see the differential gears.
Can You Tell Gear Ratio From Vin?
A car’s VIN is usually found on the dashboard or on a tag that hangs from the driver’s side windshield. It may also appear on official paperwork. It is not impossible to find a VIN online. There are several free sites that can decode VINs, while others require a small fee. A vehicle’s VIN starting with “1” indicates that the car was assembled in the United States. A VIN starting with “4” means that it was assembled in Canada, and a VIN starting with “3” means that it was manufactured in Mexico.
Depending on the car model, a VIN can also tell you the gear ratio of your car. Its length and details vary depending on the make and model, but an average 15-digit VIN will reveal a lot of information about your car. It will tell you the year, make, and model of your car, as well as the number of cars made. It also allows you to determine the vehicle’s rear gear ratio.
How Do I Know What Size Rear End I Have?
There are a few different ways to determine the size of your truck’s rear end. Fortunately, these methods are not hard to use. First, you can look at the bottom line of the rear end’s axle tag. Second, you can use a visual reference to identify the size of the differential cover. If all else fails, you can always consult the manual. And third, you can look at the third member of the rear axle to see if it has a tag that contains the serial number and dimensions of the rear end.
If the inspection cover bolts aren’t visible, you can also use your vehicle identification number to determine the size of the rear end. For instance, a GM vehicle will have ten bolts for a rear axle. An 8.5-inch vehicle will have 12 bolts and a seven-inch model will have eight bolts. A Chevy truck’s VIN is a very helpful tool to determine the size of its rear end. It also will tell you which ratio it has. The difference between 7.5 and 8.5-inch rear ends is usually visible on the differential cover. The 7.5-inch version of the axle will have a rounded edge on one corner, while the 8.5-inch version will be more squared and rectangular.
How Do You Decode a GM Rear End?
When you want to diagnose your vehicle’s rear end, one of the first things you should do is identify the rear end ratio. The ratio represents how well the vehicle’s suspension works. This ratio can vary from car to car, but you can easily find out what it is by identifying the VIN. The VIN can also tell you the vehicle’s make, model, and year. You can also identify the different rear ends by looking at the differential cover.
The stamping on the rear end will contain a 2-letter ratio code, a four-digit month/year number, and a single letter indicating the rear axle assembly plant. Some of the stamped letters aren’t very deep or neat. For example, a stamped letter “E” may not be stamped very deep on the axle housing, depending on how it was stamped. However, it is important to note that this letter indicates the rear end ratio was designed for Positraction. In some cases, the letter “E” may have been considered redundant, which is why it is often not stamped on many rear ends. However, beginning with the 1970 model year, there was an addition to the rear axle ratio codes: “C.” This stands for Chevrolet.
Before rebuilding a rear end, it is important to know the rear end’s lineage. In most cases, the axle housing will have the casting number located three inches from the center section. The number of ring gear teeth on the pinion gear is also considered an ID cue. Using this information, you can determine the type of rearend housing.
