How do I know my rear axle ratio?
How do I know my rear axle ratio?
Turn the wheel TWO revolutions and count the number of driveshaft turns. The number of driveshaft rotations will help you determine your rear axle ratio. For example, if it turned 3 and a half times, it’s a 3.50:1 ratio. If it turned 4 and a quarter times, it’s a 4.25:1 ratio.
How can I find out my gear ratio?
So an easy way to determine your actual gear ratio is to check the tag attached to the differential cover by the cover bolts. On the tag there should be some numbering such as 3.54 or 3.73, either of those numbers will give you the stock axle ratio.
How do you calculate the differential ratio on a Land Rover?
Figuring out a differential ratio: If you have an unknown differential sitting in front of you, you can calculate the ring and pinion gear ratio by counting the number of teeth on both the ring gear and the pinion gear. Divide the number of teeth on the ring gear by the number of teeth on the pinion gear and you get the differential ratio.
What do you need to know about axle gear ratio?
People who are buying a used vehicle, or shopping for an axle from a junk yard, frequently need to know what the ring and pinion gear ratio is in the axle’s differential, as well as whether or not the axle has some sort of traction control device like a limited slip, locker, or spool.

What is the formula to calculate gear ratio?
They are introduced to the concept of ratio as a way to express these relation- ships. Students derive the formula for finding the gear ratio of a pair of gears: gear ratio = teeth in driven gear/teeth in driver gear.
How can I tell what gear ratio I have?
Count the number of teeth on the drive gear. One simple way to find the gear ratio between two interlocking gears is to compare the number of teeth (the little peg-like protrusions at the edge of the wheel) that they both have. Start by determining how many teeth are on the drive gear.
How to tell which gear ratio I have?
Part 3 of 5: Determining an approximation of your car’s gear ratio Place a visible mark on the driveshaft near the differential housing. Use the chalk or paint pen. Spin the driveshaft by hand. While spinning the driveshaft, count the revolutions by watching the markings, as well as counting the revolutions of the tire at the same Continue spinning the driveshaft.
How do you find a gear ratio?
Divide one teeth count by the other. Now that you know how many teeth are on each gear, you can find the gear ratio relatively simply. Divide the driven gear teeth by the drive gear teeth. Depending on your assignment, you may write your answer as a decimal, a fraction, or in ratio form (i.e., x : y).
