CV JOINTS

Inner CV joints connect the drive shafts to the transmission, while the outer CV joints connect the drive shafts to the drive wheels. The CV joints are needed to transfer torque from the transmission to the drive wheels at a constant speed, while still accommodating the up-and-down motion of the suspension. Problems arise when the joint boot gets damaged. This allows grease to escape and dirt to get inside, which wears the joint out.
