Mine is not leaking. But it definetly has a problem. The right rear started out as a slight popping/creaking noise when I would pull into driveway/over speed bumps/go under 12mph. Now it has gotten progressively worse. I can open the trunk and barely push down on the car and replicate it a million times. Now left rear seems to start to be making it a little too. I removed the right rear inspdected looks like on the top of the shock where it enters the body there are loose components that could result in these noises. There is a metal sleeve and a metal disc that pushes up against the rubber disc. I have never seen shocks with moving parts like this. The tolerances on the parts are like an 1/8th of an inch too so they can clank around all they want. I believe they are showas. Reinstalled extra tight. Check for the noise couldn;t really hear it thought was fixed. Jumped in later that night pulled out creak/creak, **** not fixed. Going to the dealer tommorow to waste more time showing them the noise, then they will order new shocks, take a few more days, then go back get them replaced so they will be warranty"reapired, that'll take a day, for a 15 minute job. Then they will still creak and pop until koni comes out with their product. By the way this is 07 si sedan.
