Torn CV boot
 

Hey!

I got a torn outer CV boot on the drivers side. I would prefer to wait until winter to fix it since I'll be tearing everything down for upgrades during winter. Also I would prefer to avoid messing things up now in the middle of summer..

So, how bad is it to continue driving? Can I maybe try to clean/add grease to the exposed joint as a temporary fix to avoid destroying it? Any advise would be appreciated!

There are universal split boots like this

or try this tape

I haven't tried either of these but they would be better than continuing with a torn boot IMHO.

Thanks, very good idéas.. I actually have that tape at home, I just might give it a try! :)

Well... Did this yesterday took the whole of 20min. havent dared to check if it´s still there.. ;)

Sorry for the huge pics..

dude sorry but thats bush league as ****************. I get replacing it is an ass pain, but do it properly, its not hard and it doesn't take that long.

😁👍

I don't have time for a proper repair until about three weeks from now and want to keep the car on the road.. 50/50 it will hold up.

50/50 it takes out the wires for the brake wear and speed sensors. ...but I did something like that on an old Honda once and it didn't kill me.

Good point it just might take those wires out.

But seriously, if I would try to adress it properly, is the easiest way this:

1. Jack up car etc, remove the protective alu plate and the alu cross bar on the drivers side.
2. Remove the catalytic converter.
3. Unbolt the inner cv joint from the transmission
4. Fold down the axle (outer part still attached)
5. Remove inner cv joint
6. Remove outer broken cv boot & MacGyver fix :-)
7. Put on the new outer boot from the inner side of axle. (new grease first)
8. Reattach inner cv to axle
9. Bolt everything back

Is this doable or do I need to remove the whole axle?

Just did both of mine that way. And if you get the GKN kit, it includes grease and the pinch clamps.

well, you should remove the axle so you can clean & re-grease the CV.

Would I do it? No, I would just replace the whole axle, not expensive and quicker, but that is just me.

Once you have the axle disconnected from the transmission all you need to do is remove the axle nut and the axle can be removed. If you are lucky you don't even have to remove the wheel, just the center cap to get to the nut. I was unlucky and had to remove the wheel and brake disk and use a puller to get the axle out of the hub. On the other side the axle came out with a few taps of a hammer.
I like your temporary solution... I would perhaps add some backup zip ties.

Yeah, I suppose it might "hold up" but I think the only thing it accomplishes is to keep CV grease from slinging everywhere. It can't see how it will keep grease IN the joint. I think you'll find a bunch of it lining the patchwork sleeve that you've applied. But that grease hasn't been doing the CV any good. I guess it'll also help to keep dirt OUT of the joint, so I suppose it's helpful in that sense.

A related question: Anybody out there acquire any sort of sense as to how much superior OEM Porsche boots are compared with the aftermarket ones that most people seem to gravitate to? I mean GEEEZ, the Porsche ones are 10x the price. I'd bet the farm they don't last 10x as long. That said, if they lasted 2x or 3x as long I'd be perfectly willing to make that investment just to delay the labor involved with replacing them.

I tnik additional grease would be ok. But it will gather dirt and grit.on.my Vw i used a bicycle onner tube and gorillal glue it workef for quite awhile
New boot is not that hard to do

Innovation at its best! I guess necessity IS the mother of invention! :cheers:

If you had just a small tear in the boot, I wonder if you cleaned up any leaked grease (with a solvent...brake cleaner, denatured alcohol, Goo Gone, whatever) and roughed it up a little (coarse sand paper), then used your section of the inner tube with some tire patch adhesive. Probably wouldn't work, but who knows? Obviously a temporary solution at best, but it's pretty easy...and temporary is all the OP was looking for in the first place.

Sorry alll about my typos.

Cool, my quick fix is also made of a bicycle inner tube! I added new grease to the best of my ability before I put the tube on.

Approx 250 km driven now and it still holds up, next week is the big test since I'm off for a roadtrip, approx 1500km.. Then I'll have time for a proper repair.
