2011 GL 450
@rbarnett2149 Wheel bearing. Easy in principle to replace, if you are familiar with this job. High torque and must-replace/single-use nut on the half shaft. A couple of hours job of you have the time, tools and willingness to do it. Or have an Indy shop or dealer do it.
If your front brakes are near replacement, it’s good to do them at the same time because “you’re in there”.
