RE: rear end is leaking
A TSB (Technical Service Bulletin) is one step short of a recall, meaning it is a manufacturer's acknowledgment of a known/common problem and it tells the mechanics the best way to fix it. But the consumer is fully responsible for payment, unlike a federally-issued recall that is covered by the manufacturer. Recalls are generally only for safety issues, like brakes/airbags/fuel system and stuff like that where there are documented cases of people being seriously injured or killed because of a manufacturer defect. Sad but true. You can always check for recalls of any year/make/model vehicle by going to NHTSA.gov and clicking on "Vehicles and Equipment" then follow the appropriate links.
