@hammerhead2411 - Did you happen to figure out the issue? I have the exact same sound at low speeds from the front end. The dealer told me to replace the struts but I still have it after that.
Did you ever find out the problem or how to resolve it? My driver's side mirror has had this exact same problem since I bought it new over a year ago. I've had it to the dealer twice where they replaced and mirror and "reprogramed" the truck but it still opens slower than the passenger mirror...
