I have a 04 coupe with the Tein CS coilovers, installed for about a year now. The car is used for daily driving & has never been on the track.

I can live with the coilover rattle noises in the rear, however now the rear is creaking/squeaking alot, specifically when it rains. During the summer time I heard no creaks at all. A year ago (last fall) it wasn't so bad, however it appears to be getting really bad now.

On a dry day if I simply take a hose & spray into the rear suspension area, then push up/down on the rear I can really hear the creaking noise.

My question, is this a Tein coilover problem? Or an issue with the G35? Any help would be appreciated as I would like to get this fix asap. The creaking sound really makes the car feel cheap, plus the rattles....you'll really go crazy!

Thanks for your help!
