The axle assembly allows for the transfer of power from your transmission to your wheels. The axle housing contains the differential, axle shafts, bearings, seals, and mounts needed to facilitate this power transfer. Some vehicles may have both a front and rear axle. In most cases these vehicles are primarily rear wheel drive, but the front axle can be activated manually in low traction situations.

In four-wheel or all-wheel drive vehicles, the front axle will also have provisions for steering. Low fluid in the differential can cause whining and rumbling noises, and damaged axle bearings may cause the axle shafts to dislodge from the axle housing.

If extensive damage is done to the axle assembly, it may be better to replace the entire axle assembly instead of the individual pieces. At O'Reilly Auto Parts, we carry complete axle assemblies to ensure you have everything you need for a complete repair.

But how do you know if your vehicle has a differential? The differential in your vehicle accomplishes a variety of tasks all in a small space. The main purpose of the differential in your vehicle is to multiply the power transmission devices. Your vehicle has just one engine but must drive 2 or 4 wheels with that engine.

Most four-wheel drive vehicles have a front and rear differential. For vehicles that are front wheel drive, the multiplication happens inside the transmission, which can technically be called a transaxle.

A transaxle takes one input from the engine and turns it into 2 outputs, one to each of your front wheels. In the case of a 2-wheel drive vehicle that is rear wheel drive, power exits the transmission through the driveshaft and the driveshaft provides a single input into a differential. Inside the differential that single power input is split into two shafts, the axles, to supply power to both rear wheels.

The differential in your vehicle also provides another important drivetrain feature and that is providing the final drive ratio. Even with the gear reduction in your transmission, the driveshafts in your vehicle are spinning very quickly so you need one final gear reduction to reduce the speed. This requires a ring gear, pinion gear, spider gears and carriers to support them. This set of gears requires specific types of lubricants to make sure things stay cool during normal operation and that wear is kept to a minimum.

Along with the gear set, very specific bearings are used to carry the loads on the shaft and keep the gears at exact distances from each other so the gear teeth can engage properly. Like any lubrication, there are seals to keep the lubricants from running out of your differential. Some differentials put these seals just outside the bearings, while others have the seals all the way at the end of the axle tube. Due to different designs, your differential can leak from many different places making it difficult to determine the exact leak location.

However, many people find that rear differential leaks are the most common. Rather than searching for where your leak is coming from, simply add BlueDevil Oil Stop Leak to your differential oil through the oil fill plug and your leaking seal will be reconditioned and restored while you drive!
