Rear axle and bearing noises. Marquis bought new. Owner's son-in-law noted minor bearing noise in rear when visiting in 2004. Son-in-law received car after death of mother-in-law in 2012, car had 24k miles at that time. Noticed pronounced rear end noise at that time (a whaa-whaa-whaa matching speed changes). Left rear axle and outboard bearing found to be pitted and were replaced by independent repair shop. Research by owner indicates that axles for this, and other similar mercury and fords had factory axles installed that had not been properly heat treated. Now, nov. 2014, at 43.4k miles the right axle is starting to exhibit noise similar, so repair is up-coming. Will examine the federal safety agency recall 04v328000 as noted here in other comments posted. Also reference ford/mercury service bulletin 0355.

Premature failure of rear axle shaft bearing. Original the federal safety agency recall # 04v328000 in july of 2004. My car was not in the original recall, but I have just had this very problem with my car. If I hadn't taken the car in, I could have had a major safety problem if the bearing had gone out totally. Please force ford motor co. To expand this recall to pay for similar repairs even if not included in original recall. A car with only 50,000 miles should not have this problem!
