Constant velocity (CV) axles are important parts of your vehicle. Not only do they transfer power to the wheels, but they also allow for flexibility when driving. This is necessary for turning the vehicle at a variety of different angles as well as driving on bumpy roads. Almost all cars are equipped with these axles and some of them even have them in the driveline.
CV axles are made of bearings and cages, which allow for the axle to change its length as it moves up and down. They also help the joint to rotate and deliver power on various planes and angles. These bearings and cages are protected with grease that is contained in a very flexible rubber boot. Without this boot, grease would leak out of the CV joints, leaving them dry. In addition, it would allow grime and dirt to collect on the axles, causing permanent damage.
These rubber boots naturally wear out over time, and as a result, they will sometimes need to be replaced. When a CV axle boot is damaged by a crack, tear, or other deformity, grease will slowly leak out and dirt and moisture will make its way in. This will contaminate the joint and wear it down very quickly. As a result, it’s best to replace the whole CV axle instead of just the boot, since grime and other contaminates will likely have already made their way in.
However, if you inspect these boots on a regular basis, you may be able to catch the problem before it has caused any damage to the joint. This can end up saving you hundreds of dollars since replacing CV axles can be very expensive. The best way to see cracks in the boots is if you turn the steering wheel as far as you can to each side. You can also ask your mechanic to check them whenever you get your oil changed, as it will only take a minute.
If you are unsure if your CV axle or boot has been damaged, there are a few signs you can look for. You may hear a clicking, cracking, or clunking noise while you are driving, especially when turning, accelerating, or decelerating. If you hear any of these sounds, you will need to take your car in for maintenance as soon as possible. When the axle fails completely, the car will not be able to drive since it cannot transfer power to the wheels any more.
If you ever notice anything unusual happening with your vehicle, it is always best to have a professional look at it before anything worse happens. For more information on CV axle repair in San Diego, please visit this website.
