2003 Mercury Grand Marquis, the built date is 10/2002. Grinding noise at right rear axle and fluid leaking at right rear axle seal coating the rear brakes. Right rear axle bearing and shaft assy failure per NHTSA campaign id number 04v328000. The vehicle belonged to my 75 year old father whom passed away last year. I now own the car. I'll assume the problem has existed for quite some time. According to Ford motor company there is no such problem with this vehicle. However, Ford does sell a half shaft rear axle bearing repair kit part number 4a109 $618. 91 to fix the problem. Can't seem to get Ford Lincoln Mercury to cover cost of repair.
