I can't tell you how easy and convenient Raxles made the whole procedure. It was so easy, I am looking around for another car to work on. With your assistance and your axles, anybody can do it. I will never replace a CV boot again and I will definitely spread the word about Raxles Inc. My daughter was delighted with the enclosed "gift" pocket knife.

Thanks, Russ Allen

CV Axles Fundamentals

Constant velocity joints because of their unique ability to overcome some of the design limitations of conventional Cardan style U-joints, have become a common component on many of today's drivetrains. You'll find CV joints used on many rear-wheel drive (RWD) and four-wheel drive (4WD) vehicles as well as on all front-wheel drive (FWD) vehicles.

 Some type of flexible coupling is needed on all open driveshaft to accommodate the up and down motions of the suspension. What's more, some means of allowing the driveshaft to change length or to "telescope" in and out must also be provided because the distance between the ends of the shaft change as the operating angle of the shaft increases


 What causes a driveshaft to change length as it swings up and down? The geometry of the suspension. In a FWD vehicle, for example, the arc through which the front suspension travels is determined by the length of the lower control arm (Figure 1). Up and down motions of the suspension cause the front tires to scrub in and out slightly. Since the driveshaft (which we'll refer to as a haftshaft) is almost always a different length than the control arm, it wants to swing through a longer arc than that of the suspension. This would create an interference angle between the two that would tend to bind up the motions of the suspension. That's why the driveshaft must be able to telescope in and out (Figure 2) because doing so enables it to follow the same arc as the suspension.
