Signs You Have A Bad CV Axle

The front end of your car is actually quite an engineering marvel. The fact that several complex systems all work in tandem with each other in close proximity is remarkable. In fact, one of the most remarkable accomplishments is the transfer of energy from the engine and transmission to the wheels themselves. The way this is accomplished on front-wheel drive vehicles and others is with the use of the constant velocity (CV) axel -- also sometimes referred to as the halfshaft. This is what transfers power to the wheels, so a damaged CV axle is kind of a big deal. These are the 5 easiest ways to identify if you have a damaged CV axle.

Your CV Axle is Very Important for a Smooth Ride 

5. Vibration While Driving

Because the CV Axle joints are located right next to the vehicle's wheels, any damage to them can directly affect your driving. If you suddenly feel as though your vehicle is vibrating more than normal, it can mean that you have a damaged halfshaft. However, there are many other problems that could cause extra vibrations, so if you do experience this symptom, it's important to look for other tell-tale signs of a blown CV Axle.

4. Clicking While Turning

Part of what the halfshaft does is allow the wheels to turn while giving them power. The rubber boot on the CV Axle Joint protects the joint that allows the wheel to turn. If that boot is damaged, it could affect your turning. If you suddenly hear loud clicking while turning- whether just in one direction or in all directions- that is a good indication of a blown CV joint. Again though, there are other possible reasons for a clicking, so best not jump to conclusions and instead let a professional officially diagnose the problem.

3. Knocking Sound

Similar to the point above, if you suddenly start to hear a knocking sound while driving, your CV axle is a potential culprit. Even if the knocking isn't the fault of the halfshaft, there's rarely a minor cause for sudden knocking. Should a knock suddenly appear, it's best to have a professional take a look as soon as possible. Our team at Capitol Toyota would be happy to schedule you an appointment and take a look for you.

Grease Leaking Out of Your CV Boots Means They Need to be Replaced 

2. Grease Found on the Inside of Your Wheels

The boot of the CV Axle is heavily lubricated to ensure full-performance. If any damage is done to the boot, that lubricating grease can leak out onto your wheels. This isn't as obvious as a sudan click or knock, but it is an easy way to confirm any suspicions regarding the health of your halfshaft. If you suspect you have a damaged CV boot, be sure to check the inside of your tire for grease- if none is found, you may have an entirely different problem on your hands.

1. A Tear in the Boot

This is fairly obvious, but most of the other symptoms here could potentially have alternate causes; however, if all signs point north, it's best to walk north. In other words, if you exhibit several signs of a blown CV axle, there's always one sure way to find out: inspect the axle. In order to do this, you'll need to crawl under your vehicle to inspect the CV axles that connect to your wheels. Or, you can always call us at Capitol Toyota and schedule an appointment so we can take a look for you. If a tear in the rubber boot is found, it will need to be replaced. Often, that's all that's needed. However, if a torn boot isn't addressed quickly, the joint can run without grease and be damaged as a result. At that point, replacing the entire CD axle is typically best.
