CV Joint Grease?

[NV Zeno]

('83 Wagon)

 

OK, here's my situation, maybe this'll help explain where my question is coming from: My passenger side outer boot has a hole in it. Not a tear (I've seen plenty of those), but a puncture..sort of like something small flew up from the road and stabbed my joint boot.

 

Of course, I "caught wind" of the damage shortly after, who can mistake that smell:-p ?

 

Here's the question: If the grease inside is flinging around and outward to the inside of the boot, is there any grease that's actually staying on the actual working part of the joint? It seems the grease that's escaping through the hole is being done so with a lot of force and speed (which is expected), leaving the actual joint dry.

 

Do you follow me? I'd be happy to explain more if anyone has questions.

 

 

Thanks.

All of the CVJs I have rebuilt (over about 18 years) had plenty of grease on the working parts. Lots in the boot also. It must "circulate" around in there somehow. It's pretty thin at room temp, must get thiner heated up under load. I always buy used ones & rebuilt them, or get used ones off parts cars.
