To find the axle gear ratio for *your* Chevy Express, you need to:
* Check the vehicle's specifications sticker: This sticker is usually located on the driver's side doorjamb or the glove box. It will list the axle ratio.
* Look at the Vehicle Identification Number (VIN): A dealer or mechanic can decode the VIN to find the specifications, including the axle ratio.
* Consult your owner's manual: The manual might list the axle ratio.
* Inspect the axle housing: The ratio is sometimes stamped directly onto the differential housing itself (though this requires getting under the vehicle).
Without knowing the specific year, make, model, and trim level of your Chevy Express, it's impossible to provide a definitive answer.
