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.
The drive axle consists of two constant velocity (CV) joints, each with its own rubber boot. Whenever a CV joint boot is damaged for any reason, water and dirty will get into the CV joint causing it to wear out prematurely and fail eventually.On this car one should replace the entire drive axle, instead of trying to replace the CV joint or boot itself. I bought the drive axle for about $60 from Pep Boys.It might be a couple of bucks cheaper at NAPA Auto Parts.henever a CV joint boot is damaged for any reason, water and dirty will get into the CV joint causing it to wear out prematurely and fail eventually.
