Edit: Found source in post #7
I've been hearing this ticking noise for over a year. When I was in warranty, the dealer said they couldn't hear it, I can't not hear it now. Now I'm only covered by CPO and Powertrain, and from what I've been told, CPO won't do jack for this.
Happens while cruising if I'm giving it slight gas or hitting bumps. This also happens when the vehicle is at a standstill and in drive if I creep forward and then hit the brakes, I can make it tick once or twice. Doesn't tick in reverse and doing the same thing.
You can hear the ticking throughout the video; here is the timestamps to the most audible point. You will hear it in the first second of the video as well.
0:25 - 0:31
This video was taken in March, and it's the same noise today.
I'm going to take the wheel off tomorrow and look around/clean the mating surfaces, and will also be ordering rear diff fluid to do a fluid exchange.
If I can't find the source, then probably crawl back to the dealer and have someone sit in the car with me.
