The inner CV joints (tripodes) on my V6 are running at a small angle and it seems that when road speeds get 'enthusiastic' the CV boot starts to wobble and very quickly splits, letting all the grease out into my engine bay

Does anyone know of a more rigid type of boot which will not go out of shape so quickly?

I can't remember which book I read it in, but a trick of the racing types is to put a cable tie around the center of the boot to stop it expanding and wobbling at speed. This might help you out?

GKN do 'fast boots'

We run something similar on our Formula Ford two litres to the piccy shown above (except we run cv's at both ends.) I hadn't had much to do with them until the other day when I stripped and reassembled both driveshafts. An old boy that has worked on then for years told me to push the small diameter end of the boot (the bit in contact with the driveshaft) in towards the joint to stop the boot twisting. (we don't run oetiker clips or cable ties on any of our boots on the Formula Fords either) Might be worth a try as we never have any problems with ours. I'd never seen the above done before until this old bolty pointed it out to me.

Aha now that makes some sense - it should encourage the concertina sections to keep a little closer and making the whole boot more rigid.

Russ, when you say that you don't use any clips or ties, how do you keep the boot in place on the driveshaft and tripode bell?

Too much grease ?

Did think about that - I used the sachet of grease that came with the boot kit so I doubt they are overloaded. I will make sure when I get time to replace the boot - it seems to only leak above 120mph (on a private track of course)

I would imagine it would be ok to whip off the old boot with the excess grease and just pop on a new boot without adding any extra grease - any more grease than can fit inside the tripode bell is useless anyway right?

Sorted!

Mike, you are spot on I have been using aftermarket boots so this time I went to my local Ford dealer and ordered genuine parts. They are more like the 'fast boots' pictured above and are really stiff compared to the concertina style aftermarket ones which are very floppy.

There's a moral there somewhere ....

I decided to get the 'fast boots' for the outer joints too (might as well while its all stripped down) £65 for all the boots Ah well, its only money

Here is a pic of the quality boots - far superior to the aftermarket jobbies.
Tridod boot is front left and Lobro boot is front right.
