Shock bushing failure in the rear can allow the shock absorber to contact the body and cause a squeaking noise over bumps in the rear. The faulty rear shock absorber bushings should be replaced.

2007 Mercury Mariner Reviews
Bought my 2007 Mercury Mariner LX V6 4WD, used in 2009, with 24,000 miles. For the first year, I believed I had made a good purchase, however having to replace brakes (pads and rotors turned) at 30,000 miles. I didn't give this a second thought as the brakes may have never before been serviced. Then at 37,000 miles I had to replace them again. At 44,000 I had to replace the rotors, as well. The car "eats" brakes. OK, so now we're at 71,000 miles. The transmission has gone and needs to be replaced. $4,000.00 bill. No car should require a new transmission at 70,000 +/- miles. I had owned a Ford Bronco (1986 V8, 4WD, Eddie Bauer Edition - purchased brand new) that was such a mechanical-failure-nightmare, I swore I'd never buy another Ford product again in my lifetime. Well, I bought the Mercury Mariner (first Ford failure... shame on them; second Ford failure... shame on me), and my vow has been re-established. Never again will I buy a Ford product. I've had three Jeeps and not so much as a single major repair. I have now had two Fords and they are nothing but mechanical headaches. No wonder the Japanese, Germans, and Koreans are taking over the auto industry, huh? They build quality and reliability. Something the American car makers don't understand.
