FAQ
Is this seal compatible with my 2008 Chevrolet Colorado?
Yes, the seal is listed for Chevrolet Colorado model years 2004‑2012. Verify your VIN for exact sub‑model compatibility on the product page.
What is the recommended torque for installing the seal?
Apply a torque of 25‑30 Nm to the shaft retaining bolt after the seal is seated to ensure proper compression without damaging the rubber lip.
Can I reuse the seal after removal?
We recommend replacing the seal each time it is removed, as the rubber lip can become deformed, leading to potential leaks.
Does the painted coating affect heat dissipation?
The paint is a thin, heat‑stable coating that does not impede the seal’s ability to operate under normal transfer case temperatures.
What warranty does AUTO DN provide?
The product includes a 1‑year limited warranty covering manufacturing defects and a 60‑day money‑back guarantee if the seal does not fit your application.
