Brennan, you and i live in similar weather conditions so i'll tell you.
In temperatures below 5 degrees it CLUNKS loud, espcially when the car has been outside overnight and when the car is still cold. After driving for at least 10 minutes and everything has warmed up, the clunk may not be as noticable even if the temperture outside is below 5 degrees.
Over 5 degrees, the clunk is no longer audible or it doesn't even clunk at all. I guess the bushing has gotten warmer so it's more flexible.
