Hello. Does the noise only occur when driving or also at a stop ?

Customer: replied 2 years ago.
Only when diving forward or reverse.
Expert:  Lou P. replied 2 years ago.
Does it change with speed ? Does it get louder or just faster ?
Customer: replied 2 years ago.
it's affected by speed of vehicle. Speeds up and slows Down. Just like a playing car pinched by a clothes pin on a bike front tire. Turning does not matter...clicking is present in turns and straight aways. Also is present when car is in neutral, and coasting. Is present even When brakes are not applied. Temperature does not matter.

Ok, that is great ! Your info is very helpful in ruling out a lot of issues. Couple more questions.
How new are your tires?
What kinds of roads do you drive on , any gravel roads , or gravel driveway ?
Can you roll down each window individually and tell which wheel area it is coming from ?
Customer: replied 2 years ago.
Brand new - OEM graded tires. asphalt roads w/bumps. Many bumps...It's michigan! 😀 so rough roads.
Customer: replied 2 years ago.
the dealership claims lca are good.
Customer: replied 2 years ago.
I suspect bad ball joints on lca..but they do no.
Expert:  Lou P. replied 2 years ago.
Ok hear me out on this. With new tires and gravel roads you will get rocks stuck in the tread. And they will give you that noise. That's why I ask if you can locate a corner of the car by lowering each window in until the noise gets loud. It has to be a rock in a tire tread or nail but you would have a low tire message. That is the only thing that makes sense. Ball joints only make a knock over bumps. Same with all suspension. Brakes and bearings will never make a click noise. Lower control arms on your model are very stought and will not make a rotating click noise. The only thing that makes sense. Especially from all the info you have given me. I know this may sound far fetched but new tires have the greatest amount of tread. Therefore more space for rocks to get caught. Happens ALL the time. Not all technicians are smart enough to think outside of the box. Let me know if this helps. Usually the shiniest rock in your tread is the one that is making the noise. Hope this information helps. Let me know. Lou

I used to live here in Michigan .......👉🏻✋🏻😉
I know you know what that means (as long as the emoji went through proper lol)
Customer: replied 2 years ago.
Unfortunately it's not that simple. No rocks are found in thread. I ensure I pick them out a test drive. Noise still exists.
Expert:  Lou P. replied 2 years ago.
Ok , so you work on your car yourself ? Or always take to mechanic ?
Customer: replied 2 years ago.
Knowledgable on simple things...mechanically I will always take in for observation and recommendation. But things like stones in tires, or mud caked on rims causing out of balance conditions, tire rotations (cupping) and balancing all the more common sense things that cause road noises and vibrations I know all about. His is definitely a mechanical issue but hard to diagnosis. Like I mentioned the dealership can't even determine. I thought perhaps you would have a different viewpoint
Expert:  Lou P. replied 2 years ago.

No something like this is not common. Maybe a u joint , but to check the rear would have to be raised. Yeah from everything you say it's going to be something that rotates with the tires. Tires , brakes, rear diff, rear axles, u joints , something to that effect. That's all I got. Sorry I don't have s quick answer. Please let me know the outcome. I won't waste any more of your time.
