Crawl under the rear of the SUV. There will be 2 metal tags on the rear diff cover. 1 has the recommended gear weight oil (such as 75W140), and the 2nd will have the gear ratio. For example, 3 73 or 4 10. If it has a limited slip rear diff (most with trailer tow do), it will read 3L37 or 4L10. I hope this helps...
