Brake Grinding Noise problems of the 2002 Ford Escape

On August 26, 2014, I went to fair oaks Ford Lincoln dealership service in naperville, illinois for safety recall notice 14s02 / NHTSA recall 14v-165 repairs, and I asked them to check an issue where when brakes are applied, there is a scraping/grinding noise, followed by a knocking noise, which can affect reliable stopping and the vehicle steering stability. Safety recall repairs were completed, then it was reported that the mechanic "pushed back" the vacuum plate cover for the rotor on the driver's side to resolve the scraping/grinding/knocking issue when applying the brakes. The issue with the braking action and subsequent noises and response of vehicle exhibited itself again by the second stoplight away from the fair oaks Ford dealer location. Two days later, on August 28, 2014, I took my 2002 Ford Escape to gearhead auto sales & repair in glen ellyn, illinois for an inspection and repair cost estimate. On the lift, the issue was apparent to the mechanic at gearhead to be the right front axle being faulty, and he replaced the right front axle, with boots, clamps and grease. My issue is that the Ford dealer mechanic inspected and repaired my vehicle for the Ford safety recall notice 14s02 / NHTSA recall 14v-165 in the same proximity on the passenger side of the vehicle when it was on the lift, but he failed to find and report the easily seen faulty right front axle problem the gearhead mechanic promptly reported to me. Instead, the Ford representative falsely pointed to the driver's side front brake rotor vacuum plate being out of place as being the issue causing the scraping/grinding/knocking noise when applying the brakes. Is there any tie to the "corrosion-related separation" safety recall issue that led to the faulty right front axle condition? since my unemployment over the past 3 years, my Ford Escape has rarely been driven, and only in my local area.
