Trying to find the part number if anybody knows it for the foam insulation that was on the rear springs. I replaced the rear shocks for a friend on his 2009 hhr and it is creaking now only when driving. Put old shock back on and same sound. I noticed that the foam is missing, I thought it was the battery since it is in the back but it won't even budge when I try to move it.
Any help would be nice.
