I noticed this noise last year, only when it is approximately 70/75 degrees outside. Winter came, I live in the Midwest, and the noise went away. Now it is coming back. My chilly/cool morning commute to work (04:30AM) the suspension is silent, but the minute I drive in the late afternoon heat the suspension starts making noise.
The creaking popping type of noise happens over small bumps, bouncy roads, when coming to a stop and taking off... I guess basically when the suspension is working. I've jacked the car up and found no play at the wheels, I find no visual issues, using my prybar I can't find any play; I even tried loading the suspension by jacking it up a little. I step on the doorsill with the door open and rock the car but can't duplicate the sound.
This isn't a light sound, I actually feel l like people may notice the sound if they are standing/walking near my car as I drive by.
Anybody have a similar repair? Suggestions welcomed.
