2013-2020 Chevy GMC Cadillac Front Differential Axle 8.25″ 3.42 GU6

Why a Core Deposit Is Required

This product is sold with a refundable core deposit. The deposit is required to ensure the return of a rebuildable core, which allows us to recycle materials and reuse non-wear components during the remanufacturing process. This helps keep overall product costs competitive.

How the Core Deposit Is Charged

The core deposit is added to your order total at the time of purchase. Once your returned core is received and inspected at our facility, the deposit is refunded according to the payment method used for the original purchase.

Core Return Timeframe

To receive a full core deposit refund, the core must be received within 30 days of delivery. Cores returned after this period may be subject to reduced refunds or additional fees. Any return extensions must be approved by a sales manager in advance.

Core Refund Processing Time

Core deposit refunds are typically processed within 1–3 weeks after the core is received and inspected. Credit card refunds are issued to the original card. Check payments are refunded by mail. If you have not received your refund within three weeks, please contact us to confirm receipt.

How to Return Your Core

In most cases, your order will include a shipping document known as a Bill of Lading. You or your repair facility may return the core with the delivery driver, if applicable, or schedule a pickup directly with the shipping carrier using the phone number listed on the Bill of Lading. It is important to use the provided shipping documentation to avoid being billed directly by the carrier. If your order did not include return shipping information, please use the core return link below and follow the instructions provided.

Missing or Non-Returnable Cores

If a core is not available for return, the core deposit is retained and becomes part of the final purchase price. In these cases, only one-way shipping is required. If inventory for a specific core becomes limited, additional core charges may apply. In rare situations, products may not be available for sale without a core exchange.

Sending a Core Before Shipment

For manual transmissions, engines, and transfer cases, customers may send their core in advance. This option may extend overall turnaround time but eliminates the need to pay a core deposit. Only the product price and shipping charges will apply.

Acceptable Core Condition

To qualify for a full core deposit refund, returned cores must not have excessive damage, such as melted or cracked cases. If you are unsure whether your core meets return requirements, please contact our team before shipping.
