Key Features
This is a direct replacement rear differential assembly for the 2023 Toyota Prius. It’s designed to restore the precise power transfer and smooth operation that the hybrid system depends on. In our hands, the build quality matches what you’d expect from a Toyota OEM or high-quality aftermarket part. The gear surfaces are cleanly machined, the housing shows no signs of porosity or casting flaws, and all mounting points are true. We’ve found this unit to be one of our better-reviewed products in the axle and drivetrain category, and its reliability in customer vehicles is a big reason why.

Who Should Buy This?
Buy this if: You need a direct replacement for a failed 2023 Prius rear differential and want the balance of OEM quality and a lower price. It’s ideal for DIYers, independent shops, or owners looking for a reliable repair without dealership costs.
Skip this if: You require a brand-new part with a multi-year warranty, or if your vehicle has specific modifications that demand a custom gear ratio. If you’re uncomfortable installing a used component, a remanufactured unit with a longer warranty might be a better fit.
Frequently Asked Questions
Is this differential tested before shipping?
Yes. Every unit we sell undergoes a basic functional inspection for smooth rotation and visual integrity. It’s not a full dyno test, but we check for the obvious signs of failure. The high satisfaction rate from our buyers indicates this process is effective.
What gear ratio is this differential?
This unit retains the factory original gear ratio it was built with. To ensure you get the correct ratio for your specific Prius, we recommend confirming your VIN’s original specification or checking the tag on your old differential before ordering.
Do you offer an installation guide?
We don’t provide a step-by-step guide, as installation requires specialized tools and knowledge. We recommend consulting the factory service manual or a professional technician. The process involves supporting the rear subframe, disconnecting axles, and proper torque procedures.
What fluid should I use?
You must use Toyota Genuine Differential Gear Oil LT 75W-85 (part number 08885-81080) or an equivalent full-synthetic gear oil that meets Toyota specification LT 75W-85 GL-5. Using the incorrect fluid can damage the unit.
Where can I buy a 2023 Prius rear differential online?
You’re looking at it. Salvagepartsusa stocks this specific part. We source these from low-mileage, rear-end collision vehicles to ensure the drivetrain components are undamaged. Our sales data shows it’s a reliable solution for Prius owners.
Is the warranty the same as a new part?
No. This is a used, salvaged component. Our warranty covers it arriving in a functional, non-damaged state and gives you 30 days to report any issues. It is not a 3-year/unlimited-mileage warranty like a new Toyota part would have.
Do I need to send my old core back?
No. The price includes the core. There is no separate core charge, and you do not need to return your old differential to us. This simplifies the repair process for you.
