Don’t know the specifications of your differential? No problem. Here’s a list of the photos that will help our specialists identify the right part for you more quickly.
“Hi, I need a differential for my truck… but I don’t know the specifications.”
If you’ve ever called Gamex, this situation probably sounds familiar.
Every day, our team receives calls from truck owners, mechanics, and fleet managers looking for a differential, suspension, housing, or rear axle.
Very often, the person on the phone knows the make, model, and year of their truck… but doesn’t know the technical information we need to identify the correct part.
And that’s perfectly normal.
That’s exactly what we’re here to help you with.
The good news? You don’t need to be a mechanic or know all the technical terminology.
In many cases, a few good photos of your differential are worth far more than a long description.
In this guide, we’ll show you exactly which photos to take before contacting our team.
Why Are Differential Photos So Important?
Many customers believe they absolutely need to know:
- their rear axle capacity;
- the differential brand;
- the suspension model;
- the differential model.
In reality…
We can often identify most of this information simply by looking at a few good photos.
That’s why our sales representatives will often ask:
“Could you send us a few photos of your differential and suspension?”
A few well-taken photos often help us avoid:
- ordering the wrong part;
- multiple unnecessary phone calls;
- additional delays;
- returning an incompatible part.
A good photo of your differential can save a tremendous amount of time—for both you and us.
📸 Top View of the Front Rear Differential – Photo #1

Why is this photo important?
This view allows our team to see:
- the front rear differential to confirm the model;
- whether the differentials are standard or locking;
- many other details that help us identify the correct part.
** For a housing, it’s important to see the position of the torque rod.
Even if you don’t know the exact model, this photo already gives us several valuable clues.
Our Specialists’ Tip
Take the photo so the entire differential and the driveshaft connection are visible.
The clearer the photo, the easier it will be for us to identify your part.
📸Suspension Trailing Arm – Photo #2

Why is this photo important?
This is probably the most important photo when identifying a suspension.
It often allows us to identify:
- the suspension manufacturer;
- the model;
- manufacturer-specific design features.
At Gamex, we regularly work with suspensions such as:
- Hendrickson;
- Chalmers;
- AirLiner;
- Low Air Leaf;
- TufTrac;
- Neway;
- Reyco.
Even if you don’t know the name of your suspension, a photo of this area is often enough for our team to identify it.
📸 Rear View of the Differential – Photo #3

Why do we need this photo of your differential?
This view allows us to confirm several technical details.
Our specialists can observe:
- the rear differential model;
- certain mounting components;
- various details that make identification easier;
- rear axle capacities based on certain suspension models.
Every viewing angle provides additional information.
That’s why we always prefer receiving several photos of your differential rather than just one.
📸 Overall View – Photo #4

This photo shows the complete axle assembly.
It allows us to see:
- the suspension;
- the differential;
- the connections;
- many components that help us confirm part compatibility.
The more complete the view, the easier it is to avoid mistakes.
The Most Common Mistakes Customers Make When Sending Photos
Here are the mistakes we see most often.
❌ Only one photo of your differential
Many customers send us only one picture.
Unfortunately, a single angle doesn’t always show all the information we need.
Our recommendation: send several photos from different angles.
❌ A photo taken from too far away
When the differential only occupies a small part of the image, it becomes difficult to identify the important details.
Don’t hesitate to move in closer.
❌ A blurry photo
A blurry differential photo can hide essential details.
Take a few seconds to make sure the image is in focus before sending it.
❌ A photo that’s too dark
Under a truck, lighting is often limited.
If possible:
- use a flashlight;
- turn on your phone’s flash;
- or take the photo in a well-lit area.
❌ A photo of your differential that’s too close
We want to see the entire assembly. It’s always better to provide too much information than not enough.
What if I can’t find the identification tag?
Don’t worry.
We know that some identification tags are difficult to access, dirty, or even unreadable.
In that case:
✔ Still take all the recommended photos;
✔ Send them to us;
✔ Our team will analyze all the images to identify your part as accurately as possible.
Once again…
A good series of photos is often more valuable than incomplete or inaccurate information.
You don’t need to be an expert.
At Gamex, we’ve been doing this every day for more than 55 years.
Our specialists know differentials, rear axles, and suspensions inside and out.
Our job isn’t to test your knowledge.
Our job is to help you.
Even if you don’t know:
- your axle capacity;
- your suspension model;
- your differential model.
we can often identify the correct part from just a few well-taken photos.
That’s exactly why we take the time to guide you.
