Is that something that can be changed easily? Or does it require the entire AOS to be removed?  
 
I don’t think I have a bad AOS. It was changed at the dealer 2 years, 15k miles ago. I have no symptoms of AOS failure.

Yes, these boots can and do leak.  If yours is leaking, yes you have to remove the AoS to get a it, and I would HIGHLY recommend replacing the AoS along with the boot, and ONLY USE THE FACTORY AoS, NEVER AN AFTERMARKET UNIT.
