Front Suspension Wheel Bearing problems of the 2008 Ford Edge

Rear wheel bearing failure, have to replace bearing and trailing arm.

2008 Ford Edge, right rear suspension system, needs rear controlling arm and wheel bearing replaced. Noise from rear right of vehicle noted. Had tires checked (referencing tread), rotated, and balanced. The business noted the wheel bearing malfunction/issue and advise to take to Ford. Contacted local Ford dealership. Per phone call, was advised this had been occurring on several Edge vehicles. Once taken to shop, confirmed and advised both the wheel bearing and the controlling arm must be replaced as one. Advised back order for controlling arm, but not information available on how long it would take to receive. Asked Ford if safe to drive and was advise "yes, it is safe to drive; it just may be more noticeable/make more noise". Incident date is listed as the date taken to tire shop. Noise seem to appear approximately 1 to 1/2 months ago.
