What is going on here?
Seen 100s like that.:)
The question is how lucky you are, is it it just a case of slap a generous helping of CV joint grease all around the inside part of the joint and fit a new boot or is it a case of a new CV joint?
Usually this depends on how long it has been neglected for.;)
Although I am sure many drivers have gone to the Dealers and come away with an expensive bill for a complete driveshaft.:(

Thanks for the reply. It has driven about 100 miles like that, with the knocking becoming so loud I just stopped driving it until i could give it a proper look. Will i get away with just a load of new grease do you reckon? And how exactly do i put that in? It seems to have lost its cable tie/thingy so grease was ousing out.
 
To me that's a recent burst...if it's been like that for a long time the grease dries and there's no fresh left in the joint.

I'd suspect your knocking noise is elsewhere and you've found this while looking.

C3 did probably about 500 miles missing a boot at one point and the joint lived...and the noise I'd been chasing when I found it was a wheel bearing.
 
I already have some CV Lith-Moly Grease (NLGI 2) but it doesn't look like it will pour. The grease coming out of my CV Boot is definitely pouring.

Can I use the stuff I already have?

I presume there is some more viscous stuff that I don't know about?

Looking at your first photo the clip does appear to have come off the boot.
So if you take the wheel off, put the steering on full lock, put your "marigolds " on, then get a big handful of that CV grease from your tub and work it in past the knuckles of the CV joint turning the wheel and working even more in so you know that the actual joint is well lubricated, then straighten the steering, slap a little more of the grease in , get rid of the old useless clip, slide the CV boot back into place assuming there is no splits or other damage to it, after wiping any grease from the area the boot is going to fit over the joint, once it is correctly in place get a good new clip and securely fit it holding the CV boot on tightly.
You can use the plastic ties but only if you have the proper tightening pliers to match, I have some metal strapping that I can use , but other than that there is the proper metal straps that come in a CV boot kit along with the grease, however again you need the proper pliers to secure the metal strap otherwise the boot will slide off again with same results.
It is grease rather than oil and has a sort of "antifling" capability,it doesn't fly off once slapped all over the inside of the joint.
Some French cars used to use a type of oil in their joints from the factory, but from memory they were not exactly CV joints mostly on Renault 5s and Peugeot 104s etc.
We used to say that CV joint grease sticks like sh*t to a blanket, it is very hard to wash off your hands, hence the need for your "marigolds".;)
