evidence of a split CV boot?

[Alistair C]

Can anyone tell me what CV grease looks like when a boot has split? ....

Just taken off my near side front wheel to change the tyre & saw a concerning amount of goo splattered around the inside of the wheel. It is a dark green colour & has a paste like feel to it where it has gathered on one of the brake lines....

Looks like it has come from the big end of the CV boot but I can't see any obvious splits....
Thanks

That is def CV Greese!! Nasty stuff, dont get it on ya hands cos it never comes off!!

Best way to check it put ur car on full lock whilst jacked up and rotate the wheel cos it should stretch the boot and show any spilts there might be.

Do it sooner rather than later if its split tho, cos the CV Joint is specific to the S2 and are something like £150+vat each!!!!!!!

A boot is a fwe quid!

CV Boot for the outer is a piece of cake to do, done mine in about an hour.... Never attempted inner on the S2, have done them on other cars and are just as easy.

By the way to do it, the hub bolt is 27mm and you will need a length of scafold pole to undo it and do it up after!

The rest is simple!

That sound about right, I have swapped several CV Boots in my time and they require a knack in knockng the CV off the drive shaft. For this you need a copper faced mallet or similar.

The boots are only cheap: 5-6 quid.

sometimes a bearing can lose it's grease but I feel that it is the CV boot.

There was a better way (i think), something about redoing up the bolt and you can pull it off the shaft in that way..... but cant remember how it was done.....

You undo the big bolt that goes in your sdrive shaft, then undo the shaft from the hub. Then take the big bolt (you removed in order to take the shaft out) and wind it back in the shaft. Drive it all the way to the end and then gradually you'll notice that the CV comes off the shaft. I reassembled it by tapping on its head with a PVC hammer.

I didn't undo the hub nut, I undid the bottom ball joint, track rod end, cut off the old CV boot and by whacking the back of the CV joint with my copper mallet, I knocked it over the spring clip, replaced the boot ( Quinton Hazell) and popped it back. It really speeds up the job.

The hub nut is meant to be tightened to a specific torque and then rotated a certain number of degrees I believe..........

[Jeffer]

you're absolutely right about the hub nut. But i don't prefer to use hammers on driveshafts. In the end it has the same effect as driving the nut back in the shaft. And because of the nut hitting the shaft it'll drive off the cv.

Hi Jeffer,

are you saying that you can push the cv internals out by refitting the bolt? I have not had an Audi drive shaft to pieces so I don't know.

[Jeffer]

Yes, that's what I meant. It's very easy and effective.

How do you pull it back in?

[Jeffer]

you have to make sure the ch is in line with the shaft, then take a big pvc hammer or a hammer with a wooden block, and (gently) tap it back on the shaft. This works best with someone to hold it for you. But it'll work also if your just by yourself. Just make sure it's in line with the shaft. Then it pops on again.

I did a how to guide for this somewhere. Its dead easy to follow with the pics. DONT beat the CV off the shaft, thats just pure bodge work. I would get fired for doing that to expensive cv joints!

[Alistair C]

right looks like a job for the weekend...

Tom - is this the post you meant? Sounds fairly easy......

Just have to find somewhere to get a 27mm socket and a chunk of scaffold to fit over the torque wrench.and a pair of 'disposable' pliers.

All without driving anywhere


Do you need to use a new centre bolt each time?

My driveshaft bolts are socket heads on the rear and a feckin' great allen key head on the front, is this how it should be?
one of my front cv boots has started to crack:mad:
