Rear end liquid for Chevy Truck?

"Rear end liquid" is a colloquial term for the fluid in your vehicle's rear differential (or rear axle). For a Chevy truck, you need to use gear oil specifically designed for the rear differential.

To determine the correct type of gear oil, you need to know:

* Year and model of your Chevy truck: This will help determine the capacity and type of differential. Some trucks use a limited-slip differential which requires a specific type of gear oil.

* Differential type: Check your owner's manual or look for a tag on the differential itself. Common types include standard, limited-slip (LSD), and Posi-traction.

* Recommended viscosity: Your owner's manual will specify the recommended viscosity (e.g., 75W-90, 75W-140) for your truck's rear differential.

Do not just grab any gear oil. Using the incorrect type can damage your rear differential. Always consult your owner's manual for the correct specification. Your Chevy dealer's parts department can also help you identify the correct gear oil for your specific truck.
