I've had my pinks installed for about a month and a half and about a couple of weeks ago I noticed a rattling noise coming from the right rear. I hear it when I go over bumps or at slow speeds over uneven terrain... I'm trying to figure out what the problem is and it is only coming from that side. This is a 5-door wagon and I had the springs installed by another person, the noise is annoying and I don't want to take it into the dealership just yet. Is anyone else having this problem?
