This is a way of marking territory if they are rubbing the sides of their faces on the object. Cats have scent glands around their lips and on their chins. The facial pheromones that they mark with are signals of a happy or calm cat to other cats.
The part that simultaneously enables the axle to flex while transmitting the driving force is called a drive axle joint, and is also known as a constant velocity (or CV) joint. The CV Boot is a ribbed, rubber flexible boot that keeps water and dirt out of the joint and the special grease inside the joint.
There are 3 different kind of cv joints, but â¦ that's besides the point. The half shaft transfers power from the tranaxle to the wheels. If one goes, the car don't. You probably mean cv boot. The boot is what protects the cv joint from dirt and moisture etc. I have seen a cv joint fail anywhere from a month to a year and a half after seeing a torn boot.
