Hey everyone! I'm new here. Own a 2011 Range Rover Sport HSE and I've had this odd noise coming from the passenger rear. It sounds like a chirping or pumping sound accompanied by grinding on occasion. Sometimes it's more prominent than others, sometimes I can feel the grinding underneath my feet, sometimes it doesn't do it all. The type of road, speed, or terrain doesn't matter. There is no pattern to it. This off brand Rover shop can't seem to find the issue as it wouldn't duplicate in person 3 days in a row and I'm hesitant to take to the dealer for the same reason. Any help? Link below for video, please watch whole thing - multiple times, same noise, only 1 minute.
