My RR wheel bearing went out at the beginning of this year. I noticed it when I rotated the tires & saw the start of drippings on the inside of the rim. Got it done under warrantee but the dealer wanted extra to change the fluid - parts and labor. Go figure. It should have been part of the job but whatever.
Pickup some diff fluid before you have the dealer do the work & change it yourself that night. It'll save you about $100.
