Noise Acceptability
WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
A gear-driven unit produces a certain amount of noise. Some noise is acceptable and audible at certain speeds or under various driving conditions, such as on a newly paved blacktop road. Slight noise is not detrimental to the operation of the rear drive axle and is considered normal.
