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.

Ford l/m will not repair my 2003 Mercury marauder based on this. It is the exact same vehicle, especially the rear end. Marauder is a limited addition with the police package mentioned in the recall.
The rear end makes a thumbing noise when the vehicle speed reaches 40 mph and faster. Tires were replaced,but the noise became worse. Vehicle is currently at the dealership, who maintains that there is major problem, and the rear end has to be taken apart. There is recall 04v328000 for the rear axle fracture that consumer feels might be the cause of the noise.
