CV Joints & Boots


The maintenance of CV Joints is the perfect example of when it pays to have your car serviced regularly so parts that a close to wearing out and breaking can be identified and repaired or replaced before they actually do break and cause additional damage that is more expensive to fix. In this case, the CV Boots protect the CV joints. If the boots tear or break, the joints will start to wear away and eventually fail which is much more expensive to fix than just your CV boots.

If you haven't had your CV joints and Boots checked in a while, or you suspect they might be broken (typically you will hear a clicking sound when going around corners and/or see dark grease around the inside of the drive wheel and rims) then bring your car into our workshop in Sumner Park and we'll take a look at them for you.

The CV Joints (constant velocity joints) are needed to deliver torque to the wheels while the car is turning while in motion. There are several ways to achieve this, the most common being by using a Rzeppa joint.

The CV Boot is a rubber cover that goes over the CV Joint, seals at both ends using a metal clip and contains grease to keep the CV Joint lubricated. The boots also keep water, dirt and the elements out of and away from the CV Joint to prolong its life and keep it working properly. Since the CV Boot is made of rubber, it will break down over time until it eventually tears and lets the grease out and dirt and water in. Ideally, the problem will be identified before it breaks or shortly after to minimise the impact on the CV Joint. If the car continues being driven without a working CV Boot and grease, the joint will start to wear away, seize up and eventually fail. In worst cases this could happen while you are driving.
