This is the first time I have had one of these apart. It might be difficult to tell from these pictures but can anyone tell me if these are in OK shape or not? I have no idea how much mileage is on them. These are from a spare axle I carry on long trips. What should I be looking for when I have one of these apart?
Cheers, Elliot

Check the cage for stress cracks. If none, put it back together.

I had a hairline crack on one of mine; pretty easy to see.

If everything snaps when you put it back together you should be good to go.

Uh oh, roll the trucks. Your in the toolbox again. Look for bluing of the metal, rough spots, pitting, any scratching/scaring. Smooth surfaces are good. When reassembled and on the shaft, put it in a vice and yank on it while sliding the axle. When mine were toast they made a distinct loud clunk when yanked. Don't hurt yourself getting that beveled washer back on.

As stated above, smooth is the ticket. Truly deep grooving is on the edge and galling is the kiss of CV death. Darned messy job no matter how you cut it.

In case you haven't considered it it, use good synthetic grease on these. Massively increases CV life.

Good luck
