The rear end ratio, also known as the axle ratio or final drive ratio, is a numerical value that describes the relationship between the number of rotations of the driveshaft and the number of rotations of the wheels. A higher numerical value indicates a taller gear ratio, which means that the wheels will turn fewer times for each rotation of the driveshaft. This can be beneficial for fuel economy, but it can also reduce acceleration and towing capacity.
Knowing how to check the rear end ratio is important for a number of reasons. First, it can help you to determine the correct gear ratio for your vehicle. Second, it can help you to troubleshoot problems with your vehicle’s drivetrain. Third, it can help you to compare different vehicles when you are shopping for a new or used car.
