How to identify Chevy differential?
Identifying the type of differential in a Chevrolet vehicle is important for maintenance, repair, and replacement purposes. The differential is a crucial component that distributes power from the transmission to the vehicle's wheels, allowing them to rotate at different speeds when turning. Here's a detailed guide on how to identify a Chevy differential.
Locate the Differential
The first step is to locate the differential on your Chevy vehicle. The differential is typically located at the rear of the vehicle, either in the center of the rear axle or just behind the rear wheels. You may need to get under the vehicle or remove the rear wheels to get a clear view of the differential.
Inspect the Differential Cover
Once you've located the differential, look for the differential cover. This is a large, round or oval-shaped cover that protects the internal components of the differential. The differential cover may have the Chevrolet logo or other identifying markings that can help you determine the type of differential.
Check the Differential Identification Tag
Many Chevy differentials have an identification tag or label attached to the differential housing or cover. This tag may include information such as the gear ratio, the type of differential (e.g., limited-slip, posi-traction), and the model number. This information can be used to identify the specific type of differential in your Chevy vehicle.
Examine the Differential Housing
The shape and size of the differential housing can also provide clues about the type of differential. For example, a larger, heavier-duty differential housing is typically associated with a more robust, high-performance differential, while a smaller, lighter-duty housing may indicate a more basic, standard differential.
Consult Your Owner's Manual
If you're still unsure about the type of differential in your Chevy vehicle, consult your owner's manual. The manual may provide specific information about the differential, including the model, gear ratio, and other identifying details.
By following these steps, you should be able to accurately identify the type of differential in your Chevy vehicle, which can be helpful for maintenance, repair, and replacement purposes.
How do I know what size my differential is?
Once your differential is disassembled and its parts removed, it's time to measure your ring gear to determine its diameter. Simply measure from the widest point of the gear, tooth tip to tooth tip Pinion nut size is another parameter that can be used to identify the diff.
Where can I find Chevy RPO codes?
The GM RPO Codes location can be found on a placard labeled “Service Parts Identification” in the glove box, on the trunk floor or inside the driver's door panel. If you are unsure which part to order please contact Customer Service at 1-855-781-5992 or email [email protected].
Is 3.73 gear ratio good?
A 3.73 gear ratio is going to be good for several different reasons, depending on the application. For a truck, it is great for heavier loads where factory gear ratios that are 3.55 or 3.31.
How can you tell the difference between a GM 7.5 and 8.5 rear end?
The large square lugs on the bottom of the pumpkin are a hint that this is an 8.5” unit and not an 8.2 or 7.5. The 7.5 has lugs in this position, but they are exceedingly small. With so many potential sources, an 8.5/8.6 GM-10 bolt axle is not a challenging thing to find.
How do I know if I have a 8.5 or 8.6 rear end?
The easiest way to tell the difference is by looking at the brakes. All 8.6″ axles have disc brakes and 8.5″ have drums. Both axles use the same ring and pinion gears so that means a ring and pinion set from a present-day 8.6″ will install into a 1980's 8.5″ and vice-versa.
How do I identify my GMC rear end?

- Cover Bolt Count. Since most differentials have a unique cover bolt pattern i.e. 10-bolt, 12-bolt, or 14-bolt, counting them up will narrow the field and help you with identification.
- Axle Flotation.
- Get Your Spline In Line.
- Spec Out Your Hub.
- Pinion Size & Ring Gear Diameter.
How do I tell what gear ratio my Chevy rear end has?
You may have a different code stamped on you axle tube as well. If you can find it under the rust, it can be used to find your gear ratio as well. The only other way to find your ratio would be turning the wheel/axle by hand and counting rotations, or opening up the axle and counting teeth.
How do you tell what differential you have on a Chevy?
