why is my car making a clicking noise
This Site Was Built With You In Mind! Car Clicking Noise, What Is It? The CV joint allows flexibility
in each end of the axle shaft as the vehicle is going down the road. A CV joint on a car is similar to the ankle
and wrist on the human body. The CV
joint is what allows movement at each end of the axle shaft while the
suspension is moving up and down and the wheels are turning in either direction. Imagine trying to walk with ankles that are ridged and had
no flexibility, or try doing anything with your hands if your wrists were
stiff. Your wrists and ankles allow
movement in any direction to the hands and feet, if you didn't have ankles and
wrist, eventually you would end up braking your arm or leg, it's the same with
axles, if you didn't have a CV joint at each end, the axle would brake because
there is no flexibility. What Do the Letters CV Stand For? CV are initials, it stands for "Constant Velocity,"
no matter what angle the axle is at, it will supply the same amount of force to
the wheel from the transmission, without any extra energy from the engine.
joint consist of ball bearings mounted on an axis or wrapped in a cage,
assembled at the end of a shaft (axle). A
large rubber boot completely seals the CV joint from external elements, (moisture,
and dirt) and seals in axle grease. When Do You Change CV Joint Grease? The grease that is inside the CV joint is permanent grease,
there is no reason to replace the grease inside a CV joint
unless the joint has been exposed to the elements. The joint could become exposed to the elements if the boot rips open or if the boot becomes punctured from debris or human error. Also, the boots bands can become loose over time and could leak grease. At this point, if the CV grease leak is caught in time, and the joint is not making the clicking noise, it is possible to replace the boots and bands, repack the joint with new grease, and extend the life of the joint for another 100k miles, but only if the CV joint is not making a clicking noise. A Car Clicking Noise, Equals CV Joint Failure A car clicking noise from the front of the vehicle, while turning and accelerating, is caused by CV joint failure.
Check out this great article, " " for some great advice on how to diagnose whether the solenoid is the problem. Corroded or Loose Cables Sometimes it's as simple as having some corroded or loose wires to take care of. If you notice that some of your battery terminal connections are corroded or worn down you can test whether or not this is the issue by placing a screwdriver (with an insulated or wooden handle) between the connector and terminal post and twist it to keep it firmly in place. If you try and start your vehicle now and it works then you'll know your battery is fine but your cables connections need to be replaced or tightened. Still Having Problems?
