"Squished-out" CV joint gasket, what is happening to my new CV joints? Options

[astronomerdave]

After installing brand-new CV joints I happened to notice that they looked like this after about a week of driving.



They're rusty (the original 40-year-old CVs never rusted) but more importantly is the gasket is broken and coming out. New gaskets, torqued to specs. I've had the trans out of this car on about 3-4 different occasions, so I've removed/installed CVs at least that many times on this car without ever seeing this.

Any idea what is happening and how I might fix and prevent it from happening again?

Thanks,

I'd like to revive this old post to see if there is new advice on how to handle the CV gasket. I just did this job on my car. I was a bit pressed for time since my garage is up a slope and couldn't figure out to tow it inside, so did this in the street over the weekend and didn't quite think through the result. I couldn't get the gasket to stay in the grove since they were too tight for the machined grove (set from PMB). So all four joints are now pinching their paper gasket. I maybe could have done a better job where the shaft stubs are, but moving the joints around the trans and suspension, it's impossible not to knock the gasket out of place. As it was one side lost a ball which I had to refit while greased up under the car. That probably shouldn't be possible in new quality joints but...
Now that the car is in the garage I can try to mediate this. Duct tape sounds good. Or pull the joints apart? Then what? I don't see how I'd get them clean enough for a sealer to grab. How much does the gasket actually do? I wonder why the boot side get's away without one.
Maybe just figure on checking the bolts every year. But then I wonder if a lot of grease will get by the bolt spaces since it doesn't pinch there.
