That answered my next suggestion/question.
If you moved various wheels to that corner and only the one makes the noise, then that should rule out the CV, and rule out the bearing, since those would sound no matter which particular RW was there.
What I wrote was worded poorly.
I was trying to say that I've rotated 3 times and the noise stays at driver front.
Try removing the ring and see if the sound changes. Mine had markings on the back as though they have been moving around slightly on the wheel.
Also these forged wheels can fail.. especially if powder coated. Though if a crack was forming I'd expect some air loss.
Check the usual stuff.. how flat the mounting face is, condition of lug seats, whether any of the lugs tighten at a different rate than the others (if one feels "soft" it could be a sign of bad stud/lug/something)
I do have one or 2 rings that's rattle even when fully tightened, but the noise should have moved locations with tire rotation.
Wheels have never been powder coated, just beat up a bit on trails. All lugs seat perfectly thankfully.
I'm leaning towards being temperature related, as the more I think back to it the noise is always there in the summer then when fall comes around I stop hearing it and forget about it before swapping the stock rims on for winter. Come back to RW when weather gets nice and noise comes back.
Thinking of this as my plan of attack let me know if I should move the order around:
1. Chassis ears from a friend to see where the noise is loudest
2. Depending of where noise is, swap back to stock rims and test again.
3. While doing tire swap, check for play and closely examine RW in case something is hitting that I can't see the markings of while rim is on car.
I'm hoping for more cool days between now and then to see if in fact it is ambient temp related.
