Looking for ideas on what this might be. Car is a 2001 GP w/ 3.8, non-SC, 120K miles, I've owned since 25K.
When coming to a stop, say from 5 mph down to 0, it makes a sort of low growling noise, almost a vibration rather than a noise you can hear. Also sometimes makes the same noise starting up from 0 until 5 mph. Been doing this for maybe a year or more. I've recently replaced the front hubs (they had some play), which made no difference in the noise. At the same time as doing the hubs, I replaced the front pads (rotors looked fine) and the rear rotors and pads, also made no difference in the noise. So I figured must be the rear hubs, but when I take off a rear wheel/caliper/rotor and rotate the hub it is not rough at all, and has no play. So what the could it be? The axle half-shafts were replaced about 50K ago, they were Card One (chinese?), could they be bad and causing it? Any suggestions appreciated.
