Well as you all know, I installed some Eibach springs made for a 08-09 CTS on my 09 CTS-V. Well after the installation I started to hear squeaking noises from the car. Come to find out, it was the front springs binding up due to the extra weight from the CTS-V. The noise only was there when I slowed down, or when I was going over some bumps at low speeds. Being this is a brand new car, the noise was really annoying me.
So I decided to try and find a way to prevent the noise. First I tried putting some grease on the springs and seeing if that would work. I drove around the block and it sounded like it went away, but after driving a little bit more the noise was back.
After some thinking, I decided to put some rubber hoses around the coil of the spring. Looking at the spring, I think the noise were coming from the top of the springs because the space with the top coils were very close and I think that was where the extra weight was putting more stress on the springs.
I went to AutoZone and got about 5 feet of 3/4" rubber coolant hose and split it in half for each front springs and started to put them on. I had to grease up the spring to help slide the hose over each spring. Without the grease there was no way of putting the hose over the coil. Each spring took about 2 feet of hose for the top part, and I put 6" of hose on the bottom of the springs. After I did that, I greased up pretty much every part the spring came in contact with on the strut, including the rubber hose I had just put on.
The result: After a couple of days of driving! No more squeaky noises! I'm so glad I found out where the noises was coming from. It was annoying me pretty bad. I was about to go and cut my stock springs and put them back on. Also I think the extra hoses raised the front of the car up about a 1/2 inch. Overall the car still sits evenly with the back.
So just a warning for people who have bought these springs for their V. I would strongly suggest doing this, or wait for another company to come up with some springs made for the V.
Here are some pictures of what I did.
