chasing rattle sounds
I have two rattle sounds on my C5, both from the rear and are separate from one another.
#1 is brake related. I took my brake calipers off and detailed the entire rear wheel wells of the car. I noticed that the RR caliper has either a heat shield or a tension clip in the middle of the caliper that touches both brake pads. There are three total, one small one on the top, a small one on the bottom, and a large one in the middle. The middle one was loose and was making noise just by being moved.
I bent the clips to hold the metal piece securely again and put everything back. Went out for a test drive and it seemed to be about 99% fixed.
While out driving today, the problem is back and just as bad as it was.
I have not taken the wheel off again to see if that shield is loose again. Is this something that is required? I specifically remember taking them off of my truck one time because I forgot to put it back in while changing out pads and didn't want to get all of my tools back out.
#2 is also on the rear, but sounds like it's in the center or maybe center left.
I don't always hear the noise as the car has to be warmed up in order for it to sound. I have also figured out that the issue can be reproduced while not moving. It seems to be while pressing in the gas around 1k - 1100 rpms, it is a fairly high pitch rattle, but I can't hold the gas and chase sounds at the same time.
I'm thinking that it could be exhaust or heat shield related.
#3 (optional) - my hard top "joint" area right above the driver's seat squeaks with the body flex. Is there anything that I can put either on the seals, or in the crack to reduce the sound? This one isn't a huge deal to me as I know the body is going to move.
