27 October 2023 What a CV boot is on a car and symptoms of malfunction
Have you ever wondered about the intricacies of a car's driveline and the components that make it all work seamlessly? One such vital component is the CV joint. Found in both front-wheel drive and four-wheel drive vehicles, it plays a crucial role in transferring power from the transmission to the wheels while allowing for varying angles. Consisting of the CV joint for car and its protective boot, this assembly ensures smooth operation and protects against contamination. Let's take a closer look at this critical component in your vehicle.

What is the function of a CV boot?
The CV joint is a critical part of your vehicle's driveline system that allows power to be transferred from the transmission to the wheels while accommodating varying angles. The boot surrounds the CV joint and acts as a barrier to prevent dirt, debris and moisture from entering and damaging the joint. It also contains grease that lubricates the joint, ensuring smooth operation and minimising wear.
Symptoms of malfunction
Over time, the boot can deteriorate or become damaged due to various factors such as exposure to the elements, road debris or age. When the boot fails, it can lead to loss of grease and the ingress of contaminants into the joint, causing accelerated wear and possible failure of the joint. Common signs of a failing boot include clicking or popping noises during cornering, grease leaks, or excessive vibration.
If a boot, such as a VW Golf CV boot is damaged or shows signs of wear, it is important to have it replaced with a stretch cv boot or repaired immediately. Ignoring this can lead to more extensive damage to the joint, most likely resulting in a loss of power to the wheels or even complete failure, rendering the vehicle inoperable and also putting you and your passengers’ safety at risk.

What is a stretch CV boot?
Stretch CV boots are often used as a temporary or quick fix for damaged or torn boots, providing a cost-effective alternative to replacing the entire CV joint or axle. They can be fitted without special tools or dismantling other components, saving you both time and effort.
The Stretch CV boot is made from a durable, flexible material that can expand and contract to accommodate different joint sizes. The boot is split along its length so that it can be wrapped around the joint and then secured with clamps or zip ties to hold it in place.
TIP:
Heat your stretch boot with a blow dryer. This will allow it to become more pliant and makes it easier to fit over the joint.
However, it is important to note that stretch CV boots may not provide the same level of protection and durability as traditional one-piece boots. The split design makes them more susceptible to moisture and debris ingress, which can lead to premature wear or damage to the CV joint. As a result, they are usually considered a temporary solution until a proper repair or replacement can be made.
How much does a boot joint cost?
This small component also comes at a small price. Depending on your car’s make and model, the CV joint boot price starts at around £8, making it quite affordable to replace.
