What is a Jeep Differential Axle?
The differential axle in a jeep is a mechanism that allows your wheels to turn at different speeds. A differential allows your vehicle to turn sharp corners smoothly and to easily drive up steep hills, over rocks & through mud without compromising the drivability of the car.
A jeep differential gives you the option to take your vehicle off-road so you can drive through rocky terrain without getting stuck or damaging your asset. It’s designed for off-road vehicles because it allows the Jeep to drive through any conditions.
Like all the parts inside your Jeep the differential needs to be maintained regularly. You need differential fluid to keep the mechanism lubricated at all times to optimize your Jeep’s performance.
Why do You need Fluid for a Differential?
Jeep differential fluid is used to keep the mechanism lubricated to allow swift gear movements. The fluid oils the pinion gears that transfer power from the driveshaft to the wheel axle.
Fluid ensures that all the parts are in healthy working condition so your gears don’t stick when you’re driving. If the oil runs low or becomes contaminated it can cause the gears to make squeaking or whining noises as you turn and it can cause damage to other parts of your Jeep. So, it’s essential that you always check the fluid level of your differential axle to prevent the components inside your car from getting damaged.
How do You Check the Fluid Level for a Differential Axle?
The process of how to check your differential fluid level may vary depending on the model of your Jeep. Your vehicle’s user manual will state how often to check it, which is typically every two years or when your Jeep reaches 20,000 miles.
To check your differential fluid level, simply refer to your owner manual to guide you in locating the fill tank. Remove the fill cap and place a wooden straw inside the tank to check the volume of fluid.
If there is no fluid left inside the tank or the volume is running low, simply fill it with differential fluid designed for your Jeep model. Newer Jeep models will have an oil indicator system light that will inform you when it’s time to fill the differential with fluid.

What is a Jeep Limited Slip Differential?
The Jeep limited slip differentials are a combination of an open and locked differential. It’s designed to transfer usable power between the drive wheels of a Jeep when traction has been lost. So when one wheel loses traction the limited slip differential will transfer power from one wheel to the other.
Limited slip differentials give you better management of wheel rotation that provides optimal vehicle handling and traction. The limited slip differential is also an added safety mechanism that prevents spin-outs during turns around sharp corners.
