Axle shafts on the front of all-wheel drive vehicles connect the transmission to the wheels, allowing the vehicle to be driven. In order for the suspension to move up and down, the axles must be able to flex.

As a result, the front wheel can also bend the axle to the left or right, making it easier to steer. In addition, it is responsible for transferring engine power to the wheels. The drive axle joint or a constant velocity provides the driving power that allows the axle to flex (CV).

In order to prevent water from damaging the joint and the specific grease within, CV Boots are made of ribbed rubber and are both flexible and water-resistant.

You should never drive a car with the grease exposed, as it will be flushed out of the joint by the rotating axle, contaminating it with dirt, rocks, sand, and other debris.

The axle shaft assembly will have to be replaced if this persists. This is more expensive than buying new CV boots. As an alternative to driving with grease exposed, it is preferable to utilize a split CV boot because it is less expensive and easier to fix.

The axle shaft is covered and the seam is joined with a split CV Boot. If your CV boot is leaking, you have two options: fasten the seam with screws or tape it up. Although this is a temporary fix, the split CV boot will not last as long as the original one does.

You can use a CV joint for a long period without having to replace it if it is properly lubricated. Providing the protective CV joint boot is not damaged, this is a viable option. Having a cracked CV boot is the only time you’ll have any issues with the CV joints.

Because of corrosion and lack of lubrication, the joint will deteriorate as long as it is exposed. Check your CV boots periodically to make sure there are no cracks, tears, or loose ones.

Although inner CV joint failures are rare, you’ll sense a vibration or shaking as you accelerate up if you have a problem. Also, if you’ve been speeding up, and you’d like to slow down, you may notice some clunking when shifting from drive to reserve.

CV Split boots, on the other hand, are useless and will eventually crack even if you install them.

How Long do Split CV Boots Last?

Since they’re composed of rubber, Split SVs can go for up to 80000 kilometers or 50000 miles before they need to be replaced. Because of their durability and resilience to heat, work boots can last for several years before needing to be replaced.

Why do My CV Boots Keep Splitting?

Because of friction and movement, the outside CV joints are more susceptible to cracking than the inner ones. The location of a minor crack near the vehicle’s brakes can result in an issue with the vehicle.

There is a risk of contamination of brakes when grease is exposed.

How Do I Stop My CV Boots from Cracking?

Because your CV boots are rubber, you must take care of the rubber to ensure that they last as long as possible. Because direct heat will cause the rubber to become brittle and eventually break, it is advisable to avoid it. As a result, it doesn’t use heat to dry things; instead, it relies on air.

After a distance of 40000 to 60000 kilometers, or 25000 to 37000 miles, you should inspect your footwear. After traveling this distance, be sure to replace your driveshafts.

In order to ensure that the CV boot lasts for a long time, you should inspect your boots and replace the driveshaft. As long as you take proper care of your boots, they can last as long as your car.

How often should cv boots be replaced?

As soon as you identify an issue, you should replace the CV joint boots and the CV joints. When the crackling isn’t a problem, that is all you need to know. When you find a problem with your CV boots, you should replace them immediately.


Keep in mind that if your cv boot is cracked, you’ll need to get new ones right once. The next thing you’ll notice if you drive for a long period without replacing them are the broken boots. Breaking them will cause the grease to leak out and lubricate the joints, resulting in a buildup of friction and wear on the shafts.

In the end, you’ll have to spend a lot of money to replace the entire axle shaft assembly.
