* Under the rear cargo area: This is the most frequent location. Check under the carpeting or in a compartment. It's often tucked away, sometimes in a small storage bag.
* In the spare tire compartment: If the Jeep has a rear-mounted spare tire, the lug wrench might be stored with the tire.
* In the owner's manual compartment (glove box): Less common, but possible.
* Under the front passenger seat: Less common, but a possibility.
If you can't find it in any of those locations, your best bet is to consult your owner's manual. It should specify the exact location for your specific model.
