Axles are one of the most important components of a vehicle, as they are responsible for transmitting power from the engine to the wheels. The splines on an axle are the ridges that fit into the grooves on the wheel hub. The number of splines on an axle can vary, and it is important to know how many splines your axle has in order to properly replace or upgrade it.

What are Axle Splines?
Axle splines are the ridges or teeth that are machined into the end of an axle shaft. These splines fit into the corresponding grooves on the inside of the wheel hub, allowing the axle to transfer power to the wheel. The number of splines on an axle can vary depending on the make and model of the vehicle.
Why is it Important to Know the Number of Splines on Axle?
Knowing the number of splines on your axle is important for a few reasons. Firstly, it allows you to properly identify the type of axle you have, which is necessary when replacing or upgrading your axle. Additionally, it can help you determine what size and type of wheel hub you need, as the splines on the axle and the grooves on the hub must match up properly.
How to Tell How Many Splines is My Axle
There are a few ways to determine the number of splines on your axle, depending on the type of vehicle you have. Here are some methods to try:
Method 1: Using a Vernier Caliper
If you have access to a Vernier caliper, you can measure the diameter of the axle shaft and the width of the spline. Then, divide the diameter by the width to get the number of splines on your axle.
Tools You’ll Need
To determine the number of splines on your axle, you’ll need the following tools:
- Tape measure
- Vernier caliper
- Flashlight
- Ruler
- Pen and paper
Now that you have your tools ready let’s go through the process of identifying the number of splines on your axle.
Step 1: Locate the Axle
The first step is to locate the axle. It’s typically located at the rear of the vehicle, and it connects the wheels to the differential.
Step 2: Clean the Axle
Once you’ve located the axle, clean it with a degreaser or a cleaning solution. This will make it easier to see the splines.
Step 3: Count the Splines
Using a flashlight, inspect the axle to count the number of splines. This can be a bit challenging as the splines are tiny grooves. You can use the vernier caliper to measure the distance between two adjacent splines accurately.
Step 4: Measure the Diameter
Measure the diameter of the axle using a ruler. This measurement is essential when ordering replacement parts or installing a new differential.
Step 5: Record the Measurements
After measuring the splines and the diameter, record the measurements on a piece of paper. You can use these measurements when ordering new parts or seeking advice from a mechanic.
Method 2: Counting the Splines
The easiest way to determine the number of splines on your axle is to simply count them. To do this, you will need to remove the wheel hub from the axle. Once the hub is removed, count the number of ridges or teeth on the end of the axle shaft. This will give you the number of splines on your axle.
Method 3: Checking the Manufacturer’s Specifications
If you don’t want to remove the wheel hub, you can try checking the manufacturer’s specifications for your vehicle. The number of splines on your axle should be listed in the technical data or specifications section of your vehicle manual or on the manufacturer’s website.
Tips for Replacing or Upgrading Your Axle
If you need to replace or upgrade your axle, it is important to choose the right one for your vehicle. Here are some tips to keep in mind:
Choose the Right Type of Axle
There are many different types of axles, including solid, semi-floating, and full-floating. Each type of axle has its own strengths and weaknesses, so it is important to choose the right one for your needs.
Consider the Gear Ratio
The gear ratio of your axle will affect the overall performance of your vehicle. A lower gear ratio will provide more power and acceleration, while a higher gear ratio will improve fuel efficiency and top speed.
Get Professional Help
Replacing or upgrading your axle can be a complex and dangerous process. It is important to get help from a professional mechanic or technician to ensure that the job is done safely and correctly.
Conclusion
Knowing how to tell how many splines your axle has is an essential step in finding the right replacement part for your vehicle. By understanding what splines are, why they matter, and how to determine the number of splines on your axle, you’ll be able to make an informed decision and keep your vehicle running smoothly.
