My car sounds like a tank. There is a rattling coming from all four corners at low speed. No sound at all while on the highway. Of course the dealer was unable to find or solve the problem. I have lowering springs and they say that is the source. The car is now out of warranty.I have since had the car inspected elsewhere. They believe that the strut bushings need to be replaced. I will do so with the front first next week. A second opinion was the sub frame may be the source of the problem. 2004 G35 sedan. Any suggestions?

I Also Have The Same Problem, I Ordered The Tein Type Basic Coilover Kit For My 03 Sedan. I Still Have Warranty On My Car, But Alot Of People Warned Me The Dealer Would Not Want To Fix The Problem Do To The Price Of Parts And Labor. I Was Given An Estimate And It Would Be About 1380.00 W Labor. I Bought This Tein Kit On Ebay For 747.00 And Im Paying 150.00 To Get Them Installed. I Spent Alot Of Time Debating To Go With The Tokico D-spec Or The Tein, A Must Are Your Shock Mounts They Probably Need To Be Replaced. The G35s Have Rubber Shock Mounts, These Newer Mounts Are Offered In Polyeurethane Which Is More Durable. Hope The Mounts Help Ypur Problem.

Make sure that all the bolts on top of your stocks are tight, this is the source of 99% of the rattles.

I had a rattle in my suspension (rear driver's side). It ended up being a loose e-brake cable or something like that. It was adjusted and now no rattle and the e-brake works better.

Thanks, I'll try the easiest route first. I'll you know how I make out. The dealer will be looking at it again next month as my car is in for a recall for the gas filler line. Thanks again.
