Are you wondering what Happens When a CV Joint Goes Bad?

Many drivers are not aware that the performance of their car's wheel system is basically dependent on the condition of the CV joints and car axles.  These components are involved in the steering, driving, and braking of the car, linking the power from the engine to the wheels. They must be able to carry the whole weight of the vehicle, plus passengers and cargo.  If undamaged, these joints can last up to 100,000 miles without want for a replacement.  Preventing CV joint failure is probable by knowing what to listen for and where to look. 

What are CV joints, you ask?  Simply stated, CV joints are an intricate ball and socket joints, connecting the axles to the front wheels, essential for transferring the torque from the transmission to the drive wheels at a stable speed.  To ensure smooth operation, a CV joint is packed with grease and sealed with a rubber "boot".  So long as this boot stays intact, your joints are secure and power is supplied to your wheels. But what happens when it fails?  If CV joints fail, the effect is instant and at times risky, since power will no longer transfer from the engine to the tires. 

What happens when a CV joint goes bad?

If a CV joint begins to fail while driving, your car will start to pull to one side as one wheel loses power. When the joint breaks completely its corresponding wheel will no longer turn and although the engine may still run, the car won't move.  You may see smoke coming from the broken joint and your front tires won't point in the same direction since one will be completely disconnected from its drive axle.  You may feel vibrations or a loud clunking sound when you accelerate, along with grinding or clicking noises when you turn.

Failing CV joints pose a serious risk so be sure to get your car off the road as safely as possible and then call a tow truck.   If there is only a small crack in the outer CV joint, it may be possible to simply replace the CV boot and repack the grease.  For any major damage, a totally new joint is compulsory.
