CV joint maintenance
#16
The bolts are $.55 each from Paragon. If you are cleaning the cv's you may want to change the boots while you are there. The boots sold by Paragon are the same brand/part number as the factory. Just make sure you order the large clamp if you are changing everything. The boot kit from Paragon has the grease in it.
EDit/correction: make sure you order the small clamps. The kit comes with the large clamp.

On the rotation issue......When swapping from left to right does the Right CV transmission side go to the left CV transmission side?
Sorry for the silly question just want to be sure, seems to me that that arrangement would place the wear pattern in the same place only change the direction. What needs to be done is move the right side to the left side and place the CV that "was" next to the transmission next to the wheel side? Correct me if I'm wrong!!! This would keep the direction the same and move the wear pattern to the opposite side of the CV joint inner and outer races.

It doesn't matter which end you put on the tranny or the suspension. The outside and inside joints have opposing wear patterns. So when you flip outside to inside, the wear patterns will end up being the same.
What you want to do is take the entire axle and simulate power-transmission. With one hand, twist the inner joint forward to simulate power. Then twist the outside joint backwards because that's going to be the tire resisting the twist.
So it's not a simple matter of rotation but of twist, which leading or trailing edge of the CV-joint and cage experiences forces. Starting from the inside, the power is transmitted from the flange to the outer cage. This twists the outer cage forward which then pushes on the ball which then pushes on the inner races. So on the inside joint, the wear is on the trailing edge of the outside cage and the leading edge of the inner race.
Then the inner race twists the axle forward which twists the outside inner race forward. This then pushs on the ball, which pushes on the outer cage, driving the hub. So on the outside joint, the wear is on the trailing edge of the inner race and the leading edge of the outside cage. A mirror image of the inner joint.
So if you swap inner-for-outer on the same side of the car, the wear pattern remains the same (the twist of the axle remains the same). Only swapping the axle from left<->right will you reverse the twist and the wear pattern.
