When Dave did his boots, they came preinstalled on that flange thing.
When you order JUST the boot, how do you secure it to the original golden flange?
It fits into a groove, so do you need to crimp the metal?

mine had clamps.
you can see the clamps in the pic with the entire shaft. they look white in the pic
there is a special tool they sell here for $1,000,000. you can get one at advance for about $10.
it crimps the clamp.
I am going to try just putting the big end clamp on.

The clamp seems like a jerry rig, since the OEM does not have a clamp.
There is a channel the boot sits inside, and that channel is crushed in places.

To use a clamp, I guess you'd have to put the boot over the outside of the channel part.
I guess it can work, but that's not how the OEM stuff was assembled.

See here how the outside of the boot is tucked in, and not pulled over.

With a clamp. DIY ?

I've never seen a flange with the boot on the inside with no clamp in person. I know they exist but I have no idea what car they are for. Most cars use a flange that has the boot on the outside held in place with an Oetiker clamp.

Clearly Porsche did not like the design you show because they no longer use it. In fact, the design Porsche uses on the 997 is the design I like best. The boot flange has a channel and the the boots have a rib that goes in the channel to locate and keep it in place. I didn't even know about this new design until I bought a CV joint from Pelican that came with the new style boot. These new flanges and boots work great. I don't have to worry about the boot slipping off the flange so I don't feel the need to tighten the Oetiker clamp as much as I did with the old style flange and boot.

If you have a 10mm bolt CV joint setup, here are the part numbers I use:

CV Boot: 928-332-293-02 (GKN Loebro) - From Pelican
Flange: 911-332-259-02 (Porsche) - From Porsche
Oetiker clamp: 999-512-486-00-M395 - From Pelican

The issue I'm finding is that clamps being sold are too big (same part number as above - no coarse adjustment so not snugging up properly. What clamps are you guys using?

i think the clamps I used last time are like the small one in the pic above.
there was a course adjustment by the little tabs sticking up and slots in the clamp band. (pic above). I have one more clamp at home I can take a pic of.

mine had clamps on it when I changed it last time.
have not gotten around to the CV boots yet.
car is on stands but I was putting AC back in.

I will take a closer look to see if they can go on the inside or have to go on the outside.
pissed! I had all the coils pressure tested for leaks and my rear cond has a small leak in it,
don't really want to spend 500 on an upgrade.

well here is the deal with the boots.
the KN(?) boots are the ones to get, at least for my car.
the KN boots have a little ridge on the inside of the big end, that ridge fits in a notch on the metal flange on the CV joint, the OEM boots I got don't have that notch and don't seem to look right stretched over the flange, they actually look more like they should fit inside the flange but there is no way to clamp it.

so I ended up getting 2 more KN boots and only clamping the big end of the boot.

That's very helpful 911S. Appreciate an informed opinion

You're saying the KN boots snapped into place inside the flange gap, BC of the ridge?
No clamp needed?

What is the part number of the boot you are talking about? Is it 928-332-293-02?

Does your flange have a groove (notch) like this flange?

The GKN OEM boot with part number 928-332-293-02-M60 from Pelican has the ridge that fits in the groove. The price is $5.00 these days.

You still need the clamp. Look at the flange picture above. It holds the appropriate boot (928-332-293-02) in place well. But not well enough to forego the Oetiker clamp (999-512-486-00-M395 from Pelican).

I went back to this one

928-332-293-02-M60

the boot goes one the outside and I put a clamp on the big end only. I will see how it works with no clamp on the small end, little worried about grease coming out.,

mine are 930 CV's so not sure if it that same but yes, it did kind of have a grove on the outside of the flange for the boot to fit in,
if it is right you will know it because the boot really fits nice into the groove.

the OEM boots seemed to be stretched when put on the outside but really seemed like it should go on the inside, but of course no way to clamp it.

one other thing. line the crimp of the clamp up in between bolt holes or you will not get the bolt in.
you can rotate it after but its easier to do it right from the start.

What is the word on CV boots in 2023?

I see OE is $19
GNK for $15
and now Rein has one for $9

I'm wondering the same. I had the boots replaced last year on my 993 by a well known Porsche shop here in Denver (I did not want to do the job, looks like more of a headache on a 993). I remembered this thread and asked him about the brand. He couldn't think of the name so I assumed he got them from World Pac or something. They were $30 each. They don't seem low quality but it's difficult to tell once they're on the car.

I am changing the boots now. I went through this thread and got confused about the best method. I purchased the replacement boots and they have the thin sheet metal end instead of the beefy flange that is stock. Do I just chuck the beefy stock flange assembly (not insert a new boot on the ID and crimp) with the thin flange that cups the housing? Is there a way to replace the boot only? I see pics here of new boots that look like they install with a clamp. Thanks

GKN makes the CV joints and axles, so I would trust their boot over the others if I had to replace one today.

Rein is a lower tier parts brand of Continental -- some stuff is ok, and some is not. I wouldn't roll the dice over $6.

Timely post - I'm replacing "OE" I purchased from Pelican five years ago. Three of the four are torn on the big end. I'm going to try GKN.

Seems unacceptable.
How many miles driven in those 5 years?

I installed them at 179k and it has 239K now, so 60k miles. I guess that negates the "you need to drive them to keep them from wearing out" argument.
