Front-wheel drive and all-wheel drive cars typically use CV joint at the end of the rear axle halfshafts. A CV joint allows a rotating shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction. In the early front wheel drive systems, where a cross-shaped metal pivot sits between two forked carriers, the CV joints employed are actually not strictly CV joints as they result in variation of transmitted speed except for certain specific configurations. While they are simple to manufacture and can be tremendously tough as well as capable of providing a flexible coupling in the propeller shafts, they can however be hard to turn during an operation at extreme angles. Hence they need regular maintenance as they are more complicated support bearings when employed in drive axles, and usable only in rigid axle designs.
This is not however true with your Ford. As a distinctive vehicle brand, Ford has superior support bearings to withstand the test of various road conditions. The Ford CV joint is made superiorly strong and largely trouble-free. It is highly specified for a given application and is very reliable. Yes, there is something about being a Ford rider when it comes to transferring the torque at a constant speed to steer wheels and to accommodate up and down motions of the suspension. Here, the transmission's output shaft connects to the inner CV joint. Having the ability slide in and out, this inner CV joint makes minor changes in the overall length of the shaft assembly. This is significant in order to allow for changes in suspension travel and ride height.
Now, the main portion of the axle shaft connects the outer CV joint. Know that both the inner and outer CV joints are shielded with protective boot. The latter has the inherent ability to provide even torque transfer even while the wheels are turned sharply. The CV joint is then connected to a stub shaft joining with the wheel hub and bearing assembly. There is however a thing called a "torque steer" as a result of using unequal length shafts. This commonly occurs in older front-wheel-drive cars. Hence, today, most cars have equal length shafts on both sides to neutralize the effects of torque steer.
It is expected that your Ford CV joint will need to be replaced in the long run. And you should not rely on the CV joint sale on dealers you haven't known about yet.
