I have a 2000 X5 4.4 with about 61K miles. i took it to my mechanic
for fixing coolant hoses and some other 60K maintenance work. He
reports one CV Boot is leaking and another one cracked and has
quoted about $550 in labor charges (6-7 hours) for both boots and
about $100 for parts.

I am seeking experts' opinion if CV Boot failure is common at this
mileage and if the labor charges sound right.

Thanks,
Ajit
