* Under the rear cargo area floor: This is the most likely place. Look for a panel or carpet covering that can be lifted or removed to access the storage compartment. The tools are often secured with a strap or in a plastic container.
* Under the rear seat: Less common, but some models might have stored the kit under one of the rear seats. Check under both the second and third-row seats if applicable.
* In a side compartment in the cargo area: Some Suburbans have small storage areas on the sides of the cargo area.
If you can't find it in these locations:
* Check your owner's manual: Your owner's manual should have a diagram showing the location of the spare tire and tools.
* Look online: Search for "2004 Chevy Suburban spare tire location" on Google Images. Seeing photos of the cargo area of similar models might help you locate the kit.
If you've thoroughly checked these areas and still can't find it, it's possible the kit was removed by a previous owner.
