Toyota Gear Ratio Code (What & Why)

The Toyota Gear Ratio Code is a code that can be used to determine the gear ratio of your vehicle.

Since this code is stamped on the side of the differential, and can be used to help you choose the correct size tires for your vehicle.

Toyota Gear Ratio Code

Toyota gear ratio code consists of a series of numbers and letters, and can be deciphered as follows:

Since the first number is the ring gear teeth count.

Hence, the second number is the pinion gear teeth count. The third letter is the type of differential (open or limited slip). And the fourth letter is the axle spline count.

Using this information, you can then calculate the gears ratio using the following formula: ring gear teeth / pinion gear teeth = gears ratio.

For example, if your Toyota has a 4.30:1 gears ratio, that means that for every 4 rotations of the ring gear, the pinion gear will rotate once.

Toyota Gear Ratio by Vin

When looking up your Toyota’s gear ratio, it is important to know your vehicle identification number (VIN).

The VIN can be found on the driver’s side dashboard and is composed of 17 characters (letters and numbers).

Once you have located your VIN, enter it into the search field on our website. After entering in your VIN, select “Decode” to see a list of specifications for your vehicle including the gear ratios.

The first character in the VIN tells us the country of origin.

A = United States.

J = Japan.

1 = USA/Canada/Mexico.

The second character in the VIN tells us the manufacturer.

T = Toyota The third character in the VIN is the vehicle type or manufacturing division.

U = SUV or truck division.

The fourth through eighth characters in the VIN tell us more about features specific to that particular model and engine size.

The ninth character is a security code used to prevent car cloning the tenth character tells us the year of manufacture.

Y=2000, 1=2001, 2=2002..

A04A Toyota Axle Code

If you own a Toyota, you may have seen the A04A axle code on your car. This code indicates that your car has a rear-wheel drive axle.

The A04A axle is a popular choice for many Toyota owners because it offers good traction and stability.

However, there are some things to keep in mind if you have this type of axle. One thing to keep in mind is that the A04A axle can be susceptible to wear and tear.

This is especially true if you live in an area with lots of potholes or other road hazards.

If you do a lot of off-roading, your A04A axle may also suffer from wear and tear more quickly than usual.

Another thing to consider is that the A04A axle may not be compatible with all types of tires.

If you plan on changing your tires, make sure to check compatibility with your local tire dealer before making a purchase.

Overall, the A04A axle is a great choice for many Toyota owners.

Just keep in mind that it can be susceptible to wear and tear, and make sure to check compatibility with your tires before making any changes.

Toyota A02A Axle Code

The A02A axle code is stamped on the differential housing of all-wheel drive Toyotas. It is also stamped on the front passenger side doorjamb near the VIN number.

If you see this code on your car, it means that your vehicle was built with an all-wheel drive system and is capable of sending power to all four wheels.

The A02A axle code was first introduced in 1996 on the Toyota Tacoma pickup truck.

Since then, it has been used on numerous other Toyota models including the Camry, Highlander, 4Runner, RAV4, and Sienna.

The A02A axle code is also used on Lexus vehicles such as the RX350 and GX460.

All-wheel drive cars with this axle code are equipped with a center differential that allows for power to be sent to both the front and rear wheels simultaneously.

If you live in an area with lots of snow or rain, having an all-wheel drive car can be a real advantage.

All-wheel drive helps improve traction and handling in slippery conditions. It can also help you get unstuck if you find yourself stuck in mud or snow.

If you’re considering buying a Toyota or Lexus with this axle code, be aware that these cars typically cost more than their two-wheel drive counterparts.

But if you need the added traction and stability of all-wheel drive, it’s definitely worth paying extra for!

Common FAQs

How Do I Find the Axle Ratio on My Vin Number?

To start, let’s take a look at how to find the axle ratio in your car’s owner’s manual. This should be located under either the “Technical Data” or “Specifications” section near the back of the book.

Once you’ve found it, simply flip through until you come across the section that lists all of the various technical specifications for your vehicle – including the axle ratio.

If there is no mention of an axle ratio in your owner’s manual, don’t worry – there are other places you can look.

One possibility is to check for a sticker or label on your car itself that provides this information. This is often located somewhere near where the VIN number is displayed (usually on the driver’s side door pillar).

If you still can’t find anything, another option is to contact your car’s manufacturer directly and ask them about what specific axle ratio was used on your particular vehicle model and year.

How Can I Tell What Gear Ratio I Have Without Pulling Cover?

If you’re not sure what gear ratio your car has, there are a few ways to find out without having to pull the cover off.

One way is to look up the specifications for your specific car model online. Another way is to ask someone at a local automotive shop or dealership.

Finally, if you have access to a vehicle history report, it should list the gear ratio information.

What Ratio is My Diff?

Differential ratios are used to determine how much power is sent to the wheels. The most common differential ratios are 2.73, 3.42, and 4.11, but there are many others that can be used as well.

To figure out what ratio is in your diff, you will need to find the ring gear and pinion gear ratio. The easiest way to do this is by finding the markings on the gears themselves.

If there are no markings, you can count the number of teeth on each gear and divide the number of teeth on the ring gear by the number of teeth on the pinion gear.


Therefore, the gear ratio code can be found on the vehicle’s door jamb sticker or in the owner’s manual.

Once you have the code, use the following chart to determine the ratios for each gear.
