Hi, I have a 2006 that makes a fairly loud creaking nosie in the rear when I go over a speed bump and it's cold outside. When it's warm, it doesn't occur. I've read the other posts about brake cables on the 2010 models but am not sure if this could be the same issue or not. Since the issue only occurs when i go over a speed bump and the rear of the car moves up and down dramatically, i have been thinking suspension. I sprayed wd40 on all of the suspension bushings and made sure that it was not the spare tire. Still creaks. It definately sounds like rubber on metal. Has anyone else experienced this in an 06 and resolved it?
