934 CV Cage Wear Question

[Dave04]

So I have 934s that have about 8 days of total use (over two years) here at Silver Lake in Michigan. I ripped a CV boot last trip and am cleaning/regreasing them for the first time now. 
 

I noticed that the cages have some witness marks in them from the balls. Is this normal, and if not what causes this? I had a shop put these ones in when I bought the car, and so far as I can tell everything was installed correctly. They weren’t clocked inner versus outer exactly, but otherwise appeared fine. Balls/Stars/Bodies look fine, so wear. Figured I’d ask you guys for opinions…. Car is a Desert Dynamics  with an NA LS7/S4S and Pro Am stubs in case that matters. Thanks!

Totally normal. The longer you run them the more they will 'mushroom'. That's the clicking sound people sometimes hear from their CVs. The sharp edges catch and click. You can take a Dremel and polishing stone to knock down the high spots. I do it all the time on CV cages, stars and bodies.

Thanks for the info! You guys are awesome.
