1. Under the Truck (Most Common):
* Locate the access panel: This is usually located underneath the truck bed, often near the rear bumper. It might be a hinged panel or require removing a few bolts or clips. Consult your owner's manual for the precise location.
* Lower the spare tire: There's usually a winch or a crank mechanism to lower the spare tire. The owner's manual will show you how to operate this mechanism. It might involve turning a crank or using a ratchet strap.
* Unhook the spare tire: Once lowered, you'll likely need to unhook the spare tire from the winch or its cradle.
2. Inside the Truck (Less Common):
* Locate the spare tire: This might be under the floor of the rear cargo area or in a compartment. Check your owner's manual for the exact location.
* Remove any covering: There might be a carpet or panel covering the spare tire.
* Lift out the spare tire: Depending on the size and weight of the spare, you might need help to lift it out.
Important Considerations:
* Consult your owner's manual: This is the most crucial step. The exact location and removal procedure for your specific 2005 Avalanche model are detailed in the manual. Don't attempt to remove it without consulting the manual.
* Safety: When working under the truck, ensure it's on a level surface and use jack stands if necessary. The spare tire can be heavy, so get help if needed.
* Tools: You might need a wrench or socket to remove bolts or clips securing the access panel or the spare tire itself.
Without knowing the specific location of your spare tire, these are the general steps. Always refer to your owner's manual for the most accurate and safest method.
