If you drive a car with a damaged CV, the joint will disintegrate further, making driving impossible. You'll not be able to control the vehicle and may get involved in an accident.

How long do CV joints last?

They carry the whole weight of the vehicle, plus passengers and cargo. These joints can generally last up to 100,000 miles. However, because CV axles are constantly rotating and flexing to accommodate the condition of the road, they can wear out and fail, resulting in a costly CV joint repair.

How do I check my CV joints?

Can a CV joint be repaired?

What Happens When CV Joints Fail. Unfortunately, broken CV joints are not repairable—only the CV joint boot is. If your CV joints ever fail completely, the car will suddenly not be able to accelerate, since it won't have the means to transfer torque to the drive shaft or the wheels.

Do CV joints leak oil?

Is it best to replace both CV joints?

On a high-mileage vehicle with a bad CV joint or boot, it's often a good idea to replace both shafts at the same time.

Are CV joints expensive to replace?

The cost of parts ranges between $760 and $1,030, while labor cost is between $170.00 and $180. Replacing a single axle usually takes about 1.5 to 3 hours, so replacing all four others can take up to 12 hours, which increases the cost if you factor in both parts and labor. However, replacing all four axles is optional.

What's the difference between a CV joint and a CV axle?

CV joints. Typically, CV joints are parts in the CV axle. A CV joint is an assembly of bearings and cages that allows for axle rotation and power transmission at a number of different angles.

Where is CV joint located?

Constant velocity joints, commonly known as CV joints, are located at each end of the drive shaft. They connect the wheels to the axles as well as to the transmission. CV joints shift torque at a controlled speed to the wheels.

How long can you drive with bad CV joints?

The answer will be relative from one CV axle to another. It could take weeks, months, or years. But the average lifespan of a bad CV axle is around five to six months. Knowing this does not merely mean to stretch the deadline a little bit.

Do CV joints need maintenance?

As long as these boots aren't torn or leaking out the grease, CV joints don't need maintenance and will last for many years and tens of thousands of miles. However, if the protective boot is cracked or torn, the grease will leak out and ultimately cause damage to the CV Joint, due to lack of lubrication.

Is a CV joint a serious problem?

Failing CV joints pose a serious risk so be sure to get your car into your auto shop as soon as possible.

Can a bad CV joint cause vibration when accelerating?

CV joints are located at the end of each axle. There is both an outer and inner joint. When the inner CV joint is damaged or begins to fail, you will notice your car vibrating under hard acceleration. As it gets worse, the minor vibrations turn to violent shaking when under load.

How do you prevent CV joint damage?

Your best course of action is to replace CV boots as they wear out. This maintenance prevents most CV joint damage and will keep you driving smoothly, whether you are driving to the grocery store or driving on gravel roads.
