i have an X5 4.4i sport week 46 2001 ,
a dealer recently fitted front right outer cv boot , they fitted part number 31607507403,
that is a inner boot , it squeeks when i turn steering whilst wheels rolling ,
dealer claims parts 31607507402 ( this is same as was already on the car ) would not fit at the larger end ,
they said the same of part 31607565316 although that is made of the same hard plastic as the part which they have fitted ,
dealer told me to contact bmw about the issue , i did this and as usual , bmw are not able to answer the question .
have you ever experienced any issue with cv boots for the X5 .

I dont think the factory boots fit very well, and the material is too rigid for long term use. I solved the problem by installing CVB boots made by EMPI. Better quality and more flexible.
