hey guys,
I have a 2000 Civic EX coupe and just lowered it on Koni Yellows/Eibach Pro Kit springs. The ride is awesome but i hear a lot of rattling from the rear shock/springs over the slightest bump. It sounds like a blot that is not secured down, rubbing in and out of a hole. I've checked the top nuts to ensure they are tight though. Any idea where the sound may be coming from? Extras include CTR rear sway bar and ASR subframe brace.

Thanks in advance for any help

 

Have you installed the isolators when installing your springs? Sounds like it might be that or a balljoint.

Was the CTR swaybar and Subframe installed the same time as the suspension?

Here is where the isolator is:

 

the isolator is the rubber cap that goes on top of the spring right? I'm pretty sure those were there. Where is the ball joint? is that usually included in suspension parts?

 

The isolator is not really a "cap" but more of a rubber washer. It's the big black shiny "washer" that the spring rests up on. That back lip around the isolator is part of the top hat I believe.

As for balljoints. There are many of them. Look under your car by the wheel and basically anything with a rubber boot around a joint is a balljoint.

My car used to make a lot of noise, especially in the winter. This fall I sprayed white lithium grease all over the bushings and balljoints and now I have no noise other than the springs squeaking against the isolators. Check that out maybe. Maybe someone else can come in here and suggest something as I don't know if the grease I put on is the best thing to use. It was just all I had around so I tried it.
