Compare prices on CV boot replacement

What does a CV boot do? To answer this question, you need to look at the drive shaft of your car. The drive shaft connects the transmission to the wheels and its most important part is the constant velocity (CV) axles. They have joints that allow them to move according to the road conditions. The joints are covered in grease and a drive shaft joint constant velocity boot, or CV boot for short. 

The drive shaft boot is made from rubber and is in charge of keeping the all-important grease in and any dirt out. If it wasn’t for the CV boot protecting the joint, it would wear out quickly and lead to problems with the axle. 

Signs of a bad CV boot

CV boots are quite durable and usually don’t need to be replaced regularly. But since they are made from rubber and have quite a tough job, they can wear out or even tear. Therefore it is important to have them inspected at least once a year. 
If your car has a lot of mileage or you are driving in more severe conditions, like off-roading, it is advisable to check them more regularly. While you can drive with a cracked CV boot, there is a high chance that your joint or axle will be damaged due to a lack of lubrication - that is dangerous and can lead to a very costly repair. 

Here are some signs to look out for that might indicate a torn CV boot:

• A clicking noise when turning is a sure sign that your drive shaft is about to fail due to loose joints. 
• Grease above the CV joint or on the tyre can be a sign for a leaking CV boot. In particular, the outer boots closer to the wheel should be checked carefully. 
• If you notice more vibration while driving at higher speed, this can also indicate an issue with the CV axle caused by leaking boots.
