The front wheel drive cars (FF drive), the drive shaft is the use of constant velocity universal joint, universal joint are sealed with a rubber sleeve, a rubber sleeve attack if damaged, the vehicle will run into the sand when traveling the cardan joint, accelerate the wear, shorten life. Therefore, should normally see rubber sleeve is broken. A rubber sleeve break when the picture is clear: in the rim and the engine will have extremely thick floor near the oil (the oil for butter), if in the period of moving the steering wheel when killed will have a "flap" sound, also said that the universal joint is damaged, should be replaced. The usual view that often rubber sleeve, and prevent the vehicle hit the steering wheel in place (due to the formation of the cardan joint due to overload and short life).

The rear wheel drive vehicles, the use of the drive shaft two of constant velocity universal joint, if the owners relax in the clutch, or in emergency, accelerate the rapid deceleration when the car came "KaKa" sound, said no CV joint has to replace the standard. And the way to catch the static view drive shaft center range under the car to do at the mercy of swaying movements, if the rotation of the view is too large (more than 45 degrees), that is not void CV joint is too large, the demand of maintenance.
