Power from the transmission is transferred to the rear wheels of your Nissan by a single driveshaft. In the front, however, there is a separate driveshaft for each wheel, called the Nissan axel assembly. This device must transfer power to the wheels, no matter what position they are in, relative to the transmission. The power must also remain at a constant speed at each end of the Nissan axel assembly, to minimize vibrations and component damage. Using a set of unique joints, the Nissan axel assembly accomplishes this task well. A slip joint is used to ensure that the wheels have power as the vehicle is steered around a corner. To maintain flexibility, the Nissan axel assembly also has two constant velocity joints, which allow the driveshaft to be at the correct angles to the wheel and transmission at all times. Like universal joints, if there was only one constant velocity joint on the assembly, a large amount of vibration would be produced, and the Nissan axel assembly would not be as flexible. The constant velocity joint consists of a system of gears that allow flexibility, and these gears are covered in a rubber shield, called a boot. If the boot were to suffer physical damage, the joint would immediately loose its lubrication, and dirt would enter the delicate gear system. Soon, the friction and dirt would render the joint unusable, and the entire Nissan axel assembly would have to be replaced. Fortunately, our online catalog has the perfect Nissan axel assembly for your vehicle, at a great price compared to the dealership. Ordering your Nissan axle assembly, or any other of our numerous parts and accessories, is always safe and secure, whether you use our online ordering site or our toll-free telephone number.
Nissan Axle Assembly: Some Diagnostic and Troubleshooting Tips
There are ways to tell if something's amiss with your Nissan axle assembly. It doesn't have to be a great mystery, although figuring this out can be a puzzle. You have to put together the pieces to paint a clear picture. Before the axle assembly fails completely, you have to gather the clues. Here are some hints and tips to properly diagnose the axle trouble and troubleshoot the problem:
Rumbling and vibrations
When you drive down the road and experience some rumbling or some vibrations as the vehicle accelerates or turns, chances are, something's not right with your axle assembly. The axle can be almost worn out or nearly broken. When accompanied by unusual sounds, you can almost be sure that something needs to be checked in that assembly. The problem could most likely be the CV joint. You have to check to find the right cure right away. Don't ignore even seemingly minor issues. Axle troubles can cause serious problems when driving.
Free play/excessive movement
If you suspect a fault within the axle assembly, you can always check it out up close and search for any sign of wear. Move the axle up and down. If there's free play or excessive movement, then you got your answer. The axle is probably too worn out and would need a replacement. If the vehicle has reached more than 100,000 miles, it shouldn't be a surprise at all. It's time to give the old axle some rest. As you take a closer look at the axle, also check the rest of the assembly. This will be a great opportunity for you to catch any impending trouble early on.
Those strange noises while driving can be clues to all sorts of axle assembly problems. The vehicle may turn into a chatterbox, for instance, with fast clicking that becomes a chatter as the car accelerates. There could also be some clunking from the driveline. The problem here is most likely a worn-out CV joint. Now, if there's squeaking or clicking and this is accompanied by vibration while the vehicle runs at slow speed, this could be the case of a damaged or an insufficiently lubricated U-joint. Whirring sounds as the speed increases can usually be blamed on the pinion bearings, while clunking, banging and jerking as the vehicle pulls forward could mean that the ring or pinion gear is missing a tooth or has broken teeth.
That low-pitched growl from the axle is never a good thing. This may seem like tire drone and might be unnoticeable at low speeds. But once this caught your attention, as this may also be accompanied by vibration, you'll have to check the axleshaft bearing or the differential carrier bearing. Search for any sign of wear such as leaks and scores. A damaged carrier bearing would usually require an axle rebuild. If it's the axleshaft bearing, you may have to replace the seal, bearing, and the axleshaft itself. Although it won't be easy to figure out which part of the assembly is acting up simply through the strange noises when driving, these shouldn't be ignored. Even if you have no idea which part of the assembly or the rest of system has an issue, these should be enough reason for you to have the system checked.
