The CV axle is very important to your car. Without it, your vehicle would not be able to move forward or turn. The CV axle provides the flexibility that your car needs while you are driving. You can drive with a bad CV axle for a while, but you need to get the part replaced before you cause severe damage to your vehicle. As long as you keep an eye on the joints, they can last almost the entire life of the vehicle. When you get your tires changed or rotated, have the mechanic look at the axles to make sure they are properly greased and there are no tears.
One of the ways that you can tell your joints might be going bad is if you hear a loud grinding or clicking noise when you turn your wheels. While you are driving on a straight road, you usually won’t hear anything wrong. As the joints gets worse, the noise you hear will get louder. Sometimes, dirt can get trapped in the rubber boot. This can cause grinding, and you might be able to get by with cleaning the boot and greasing it.
A common issue with the part is when the boot gets torn. If the boot is damaged, it cannot keep the grease on the joint. Without the grease, the part will fail. The outer boot normally is the first to break because it is subjected to more wear from driving. If you see grease splatters on the inside of your rims, then you should have the part looked at. At times, the joint could disintegrate and the car could potentially stop moving. If this happens while you are driving, you need to slowly pull the car to the side of the road. Have the car towed home instead of driving it.
