The main causes of CV joint failures can always be avoided with preventive maintenance carried out at a reliable workshop. The conditions of the roads on which the vehicle travels are an important factor to be taken into consideration when determining the frequency of maintenance of systems that are highly dependent on sealing quality, such as the constant velocity joint.
Hood seal failure
The most common cause of CV joint wear is Chinese Singapore Phone Number List contamination of the grease with dirt. Mud, dirt, sand and small particles can penetrate the hood seal, causing the grease to become an abrasive paste. Abrasion damages the working surface of the bearings, compromising the joint’s function. But joint damage can also be caused by incorrect maintenance.
Applied torque
Problems caused by excessive torque during the application of the joint, for example, can cause fractures in the thread or in the notch region of the part. It is recommended to use a torque wrench to apply the correct torque to the fastening nut.
Damaged or incorrectly positioned axle
Over time, flaws in the CV axle begin to appear more frequently. Warping of the shaft, wear in the notched area and damage resulting from an accident are some of the most obvious signs that the part needs to be replaced. In these cases, care must be taken to ensure that there is no difference between the new axle and the factory axle, so as not to damage the sliding joint.
If there is a difference in size between the constant velocity shafts, the bearing balls will be decentralized in the joints, generating an imbalance of tensions that reduces their useful life. These geometry flaws are fundamental causes of cage breakages, inner ring breakages and other joint components. Therefore, it is important that, at the end of maintenance, the suspension geometry is checked.
Lubrication
The recommendation for the use of grease in the CV joint is 40 g on the part and 40 g on the hood. The grease used in this type of joint is normally composed of molybdenum disulfide, a compound that allows the grease to maintain its lubricating properties at high temperatures and high loads. It is important that the type of grease is suitable and its application is correct to extend the useful life of the joint.
