What does the 8th digit in a VIN number mean?
Digits in position 4 through 9 make up the Vehicle Description Section (VDS).
The fourth through eighth digits describe your vehicle’s model, body type, restraint system, transmission type, and engine code.
The ninth digit is the check digit, which is used to detect fraudulent VINs..
How do I find the axle ratio on my vin?
Identify the VDS section, the fourth through eighth digits of the VIN. This section typically includes information such as the vehicle model, engine size and body type. While not every vehicle manufacturer includes gearbox ratio information in the VDS, this will be where the information is found if it was included.

Can you have different gear ratios front and rear?
All diffs are the same. Any difference in final drive ratios front to rear will cause failure unless a centre diff is running the DIFFERENCE of speeds.
How do you change rear gear ratio?
Replacing the Axles Ring and Pinion to Change Axle Gear Ratios. Of course, one way to get a different axle gear ratio is to replace the rear axle, but that could get pricey. The most common method is to change the axles ring and pinion. The ring and pinion are what creates the ratio in the axle’s differential.
How can I tell what gear ratio I have without pulling cover?
With the transmission in neutral, rotate the rear driveshaft by hand. Count the number of driveshaft revolutions required for one revolution of the tire. If the driveshaft turns approximately 3-1/2 times, you have a 3.54 ratio, etc.
Does VIN number tell gear ratio?
The vehicle identification number (VIN) is a 17-digit code that is used to identify and track every automobile produced. … The codes on that tag will tell you the gear ratio. The VIN will not give you gear ratios in most cases.
How do you know what gear ratio you have?
The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).
How do I know what gear ratio my front differential is?
Pull off the diff cover and count the ring gear teeth and the pinion gear teeth, then divide the pinion gear into the ring gear. That will give you the exact ratio.
How do I know what gear ratio My rear end is?
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. For better accuracy, turn the wheel 20 times and divide by 2 for your rear axle ratio.
