If you own a 2021 Chevrolet Colorado, chances are you may need to identify its rear axle at some point. Whether for maintenance purposes or to know which parts are compatible with your vehicle, knowing how to identify the rear axle on your Colorado is important. In this article, we will take a closer look at the steps you can take to easily and accurately identify the rear axle on your 2021 Chevrolet Colorado.
Step 1: Locate the Vehicle Identification Number (VIN)
The first step in identifying the rear axle on your Chevrolet Colorado is to find the Vehicle Identification Number (VIN). This unique 17-digit code can be found in several places, including the dashboard, driver’s side door jamb, or on your vehicle’s registration and insurance documents. Once you have located the VIN, write it down as you will need it for the next step.
Step 2: Determine the Axle Ratio
The axle ratio refers to the number of revolutions your vehicle’s driveshaft makes in relation to the rear axle’s rotation. The easiest way to determine the axle ratio is to look at the VIN number. The 7th and 8th digits of the VIN correspond to the axle code. You can then use a VIN decoder to determine the exact ratio based on the code. Alternatively, you can check the sticker located on the inside of your glove box, which should also have the axle ratio listed.
Step 3: Check the Rear Differential Cover
One of the most common ways to identify the rear axle on a Chevrolet Colorado is by checking the rear differential cover. The differential cover is a large metal casing located on the rear of the axle assembly. It houses the differential gears and fluid. The rear differential cover will have a shape and bolt pattern that will be unique to a specific axle type. By comparing the shape and bolt pattern to a reference guide, you can easily determine the type of rear axle on your Colorado.
Step 4: Identify the Ring Gear Size
Another way to identify the rear axle on your 2021 Chevrolet Colorado is by determining the size of the ring gear. The ring gear is located inside the rear differential and can be accessed by removing the differential cover. The easiest way to measure the ring gear is by counting the number of teeth on the edge of the gear. Once you have the number, you can use a reference guide to determine the size.
Step 5: Consult Your Owner’s Manual
If all else fails, your owner’s manual is a great resource for identifying the rear axle on your Chevrolet Colorado. It should have all the necessary information, including the axle ratio and type of rear axle, listed for your specific vehicle. If you do not have a physical copy of the owner’s manual, you can usually find a digital version on the manufacturer’s website.
