Hey guys, 2007 4R here, just passed 30K, and I'm having the same problem. Has there been any resolution on your end?
Mine is fairly evident making a u-turn and going above 5 MPH. It's no so much a clunk as it is a large, but dull squeak. Like metal to metal rubbing on something. Does this sound familiar? I've also thought about taking it in, but would prefer to diagnose it myself and fix it.
I should add that it doesn't happen when at a stop. I can turn left and right all the way with no problem. It's only when doing a u-turn and it almost feels like that when it happens, the front end shakes just a bit. Almost like something is rubbing, then breaking free. Very hard to explain. With this day and age in tech, maybe I'll try and get it on video.
Just saw
this thread and picture. I'll give this a shot this weekend and see if it fixes the problem.
