You may need to tap the balls in a bit...

Back where I can freely type.....so you're actually able to remove them, eh? Interesting. I wasn't able to rotate the ball cage over far enough to do so. Even with a wooden dowel stuck in the middle for increased leverage. So I flushed it out, blew out with air, then re-greased.

My axles aren't Volvo though....they came from WorldPac. About 9yrs ago. I'll be needing to redo the outer pass. boot as my replacement has already torn!!

Thank you. I guess I should have looked there but last night after trying to put that cage together for hours I was completely out of rational thought.

Mine had water in the inner joint (light brown goo that flowed out) and small flakes off the edge of two the bearing grooves(I have a picture but its not in focus). I'm not sure its worth rebuilding with those flaws...

What do you think about the condition, worth rebuilding or no?

Its an extra an I have no immediate need for it, although the one on the car is going bad - it vibrates a bit and is slowly getting worse.

I see now how it takes up your time

and feel your pain..
I actually let my diy garage do this for me when a ripped sleeve came up at the latest yearly test.

As long as you HAD no noise (clunking noise) before the rebuild, I'd re-use the axle, even though it didn't look "perfect".
A few imperfections are fine, nothing to worry about.
Remember these are GKN quality axles, they are excellent in terms of engineering and quality.
Once you clean out the water, dry it and pack with new grease, you are good.

Thanks. Got the part at the junkyard so I have no Idea about its prior performance. I cleaned out as much grease as I could but had to leave some in on the side with water - I spent a good half hour doing it- not much left with water in it but definitely some left.

I've got a picture of the imperfection Slightly out of focus) - will upload after lunch.

If you have some water left behind, best is to place the CV joint near a space heater and let the heat evaporates the water before putting everything back together.

Your comment about drying out the side with water in the grease is a good one - I didn't think of that and that side is already buttoned up. I was pretty meticulous about cleaning out the watery grease but there was definitely some still in there when I was done, I'd guess maybe a tablespoon or so in the recesses.

The picture of the chipped spot is attached. It was difficult to keep it in focus and get enough light on it for the spot to show up. Its about 1/16 wide and maybe a little longer in the axis direction- circled in red. The other dark grey marks are just discolorations in the surface

I may have made the chip with the drift but I don't think so. I used soft metal for the drift and was very careful about where I placed it - always as far inward on the star near the splines as possible and never near the outer edge.

On a related topic my dealer has an internet price for the OE axle of about $430 which isn't that bad. I know that's a hefty price compared to aftermarket or a rebuild but I am tempted to just buy one since it should be the best quality available I'll never have to replace it again - at least in theory.

Excellent videos CN90...thanks for posting. I didn't realize you could bang on those balls like that without damaging them. Nor force the cage so far around. Great info!

I didn't see this earlier today. It made me LOL yet it is the key to getting mine back together. I didn't want to force it but if I knew I could tap the balls with a wooden dowel I could have gotten mine re-assembled. I actually thought about doing that and decided if I had to force it I wasn't doing it right. I'll give it a try later this week. I got in 4 out of 6 by moving the cage around but the last two just wouldn't go.
