Rear wheel grinding (not Cardan shaft)

[DirectLA]

I have a 2004 Cayenne S that just started making a grinding sound coming from the passenger side rear wheel that is most evident at lower speeds. It sounds just like worn pads but it is not as I have confirmed they have lots of life remaining. It also only makes the sound when I am turning left, possibly because the vehicle's weight is being shifted to that wheel. I did a quick check and the rotor doesn't seem to have any nicks, gouges or other indicators of the cause. Could it be suspension related or the brake shroud contacting on the back side? I appreciate any advice you can offer.

First thing to check is that your wheel is torqued correctly, after that you need to get the weight off that axle and check for stones and such caught in the rotor area and also any free play in the wheel brng assembly.

Are you on Springs or Air Suspension ?

As an update, the service was done at Stuttgart Automotive in Lake Oswego, OR and it turned out the car had some debris caught inside the wheel area. They went ahead and took care of a couple of things that were upcoming while it was in the shop so a 40,000 mile service, new wipers, clean the gunk out and $1,100 later she's back on the road.
