Can a service person tell if the odometer has been turned back

What is your question?

Bought a used Flex from a dealer with only about 30,000 miles and have had ONE PROBLEM AFTER ANOTHER. Brakes (front and back) wheel bearings (all 4 wheels) and so on and so on. Car now has 60,000 miles. QUESTION: is there a way a mechanic can TELL IF THE MILEAGE HAS BEEN TURNED BACK? Really curious!
