What’s up! Finding a hidden drivetrain noise usually requires spinning the wheels at highway speeds for quite a long time. To protect my car's mileage history during a similar diagnostic session, I installed a Mileage Blocker from Dynotest
https://dynotestpro.com/ . It connects right behind the instrument cluster and blocks the mileage pulses from reaching the odometer display. What I really like about this unit is that it does not disrupt communication between electronic modules or trigger any annoying dashboard warning lights. It is a very clean, professional solution that allows mechanics to test drivetrain components thoroughly without altering the car's permanent records. It saves your vehicle's resale value while giving the technician all the time they need. It is a must-have for serious garage troubleshooting.
