The starter motor is supposed to be sealed. I read that the seals aren't available anymore. Then I searched eBay and found a kit. I am waiting for an answer that it will specifically fit my S60XL. I have the full service manual and it has an exploded view of the starter and I don't see enough seal in the image to totally keep the fluid out. I'll report back if this turns out to be the fix.
