Boot clamps CV joint drive shaft

Recommended Posts

Hi,

 

I have replaced the boots of the front drive shafts of my 996 4S. 

 

I have not used the Porsche clamps but standard boot clamps.

 

The crimped part is very high and close to the boot of  the inner joint. I am concerned that under certain conditions the boot will be damaged (this joint has also axial play).

 

Has anybody used such kind of clamps before with no issues and my worries are not necessary?

 

Does anybody know how to fix/crimp the original Porsche clamps? They are much more flat...

 

Thanks for help!!!

You can tap the crimp down slightly to gain more clearance.  The factory clamps use a standard clamp crimping tool, they just lay flatter.

Can you link me to such a crimping tool. I have searched for it, but only find the pliers required for the universal clamps, such as I used now! I have attached a photo of the genuine clamp!

 

I guess tapping on the crimp will loosen it slightly and the clamp is not tight anymore.

 

Do I really need more clearance or are my concerns not necessary?

They are called "earless" boot clamp pliers and are widely used on GM cars, Amazon sells the Lisle version which are quite good for around $20:

If you tap down just the crimp itself, it will not loosen the band, we do this all the time.  Just don't go nuts on it.
