"Here's a ball path in terrible condition, it's been ground out before..." near 1:17.
And I just love how he hammers in the balls with a steel ball-peen hammer. (Hell, I guess they went by the name of the tool!)
On a serious note, I found out today that swapping your CV shafts from side-to-side after 50k miles will actually double their wear-life. Turns out the balls skid (not roll) along the paths on the thrust side. Swapping sides changes to a new wear path. Does not help prevent breakage, which is where we tend to lose ours.
But swapping sides is easy and free if you are pulling the front diff for any reason.
Can you tell I'm trying to learn about CVs this morning? I never had a vehicle with 'em before...
