Make sure your vehicle is ready for adventures, get your CV joints checked. Golden Rule Brake can service any make and model vehicle in our three locations in Spokane, WA, and in Post Falls, ID.
Constant-velocity (CV) joints are important part of the suspension system. They connect two rotating shafts that meet at an angle, allowing for power and torque to be transmitted from the engine to the wheel without causing too much commotion. They are most commonly found on front-wheel drive and all-wheel drive vehicles, and help power transfer more fluidly across wide angles.
What Are CV Joints?
Constant-velocity (CV) joints are part of the suspension system. They are part of the assembly (drive shafts, axles, CV joints, U-joints, transfer cases, differentials, and wheel hubs) that transfers the power from the engine and transmission to the vehicle wheels.
The CV joints are used to connect two rotating shafts that meet at an angle. They are usually found on front-wheel drive and all-wheel drive vehicles, helping power transfer more fluidly across wide angles. Most four-wheel drive (FWD) and all-wheel drive (AWD) vehicles have four CV joints associated with the front axle, two inner joints and two outer joints. CV joints are encased in rubber boots that protect them from dirt and keep the grease that lubricates them from running out.
Common Symptoms of Issues:
Excessive vibrations during acceleration,
Humming or clunking sounds when speeding up and slowing down,
Grinding or clicking sounds when turning.
What Maintenance Do CV Joints require?
While CV joints are built to last a long time – around 70,000 to 100,00 miles depending on the car model. The axle assembly bears the weight of the vehicle (plus any cargo) along with the acceleration forces between you and the ground, which is why periodic checks are needed. A vulnerable part of the assembly can be the protective boots. Visual inspection is the best way to determine if the boots are in working order. They should be replaced if any cuts, cracks, or damage is noted. A leaking boot will allow the grease to run out, resulting in very rapid failure of the CV joint.
Electric Vehicle (EV) Shocks Tip:
If you are driving an electric vehicle (EV), regular front-end check ups are very important. Due to the build and working parts of EVs, they can be 10% to 20% heavier than regular internal combustion engine cars. This puts extra weight on the tires and the suspension.
Because of that additional stress, experts recommend that EV drivers get their suspension system checked periodically. CV joints could be a vulnerable part of the suspension of some EVs as the axle nuts holding the joints might come loose due to high torque reversals.
