Inner CV joint boot clamp diameters

The rubber gaiter does not need any real pressure as it can go nowhere it just has to seal.

Makes Antz "ziptie" sound even better!

Worth mentioning that most (if not all that I've found) jubilee clips fit a 7/16 socket. Some newer ones use 7mm, but most are still 7/16.

Means you can hold it in place with one hand and tighten with the other. The socket tool won't slide off like a screwdriver does, so tightening it much easier.

All of this makes sense. So as always, the answer is boring: use the correct clamp with the correct tool. Got myself some universal trimmable crimp clamps, we'll see how they work out.

One other thing that makes sense is the fact that the original clip is flat when fitted with no raised part also in the direction of rotation......with a jubilee clip stones or whatever can hit the raised slotted part hard and it may break or be dislodged and so back where you started a damaged leaking gaiter?

Hi, On a previous car I needed to dissasemble a driveshaft to check a universal joint. I didnt have the crimping tool or any knowledge of these clips or how they worked, so I took my driveshaft down to my friendly local tyre fitter garage and they put one on for me. It took about 30 seconds and they didnt charge me. I determined to buy my own tool and Im so glad I did. A few months later while replacing my front struts on my V40 the weight of the wheel hub pulled the drive shaft out of the inner gaiter and I lost my gear box oil. I removed the driveshaft complete, nipped down to my local motor factors, bought a clip, which cost about 40p. Once home I used my new tool and the clip was fitted in less than a minuite. Its so easy when you have the right tool and you never know when your going to need it.
A wise man once said "if you need to borrow a tool more than once, you need your own."

Just realized i forgot to update this.

I ended up using the universal trimmable hose clamps. I snipped them to the required length and clamped with carpenters pliers - they were soft enough and everything went smooth.

In a perfect world the boot would hold much better if there was no grease between it and the cv joint.

Might be possible on the bench but working on the car, not so much.

Always best to use crimp on clamps.

I usually use bailcast stretchy boot replacement cv boots and the slightly crappy (but adequate) clamps can be crimped with side cutters if necessary.

OEM type clamps will probably require the correct tool due to being beefier.

I've been loaned a set of knipex crimpers which I believe can be used side or end on. Before that I used to use a set of knipex nipper things which were very similar but designed for cutting wire (fence type).

Jubilee clips are awful things and unless you buy the super heavy duty ones they just break when you do them up. They are really bulky as well.

You can use those crappy stainless steel cable ties but you need the special tensioning tool otherwise it's nearly impossible to get them tight.
