Vibration coming from rear of 2003 Infiniti I35 - not rear parcel tray.

[brahmabull]

Hi guys,

I'm new to the forum. I'm a regular at twinturbo.net, but this is the first time that I've ventured over here.

I have a 2003 Infiniti I35 that I just bought for my father.

At idle, there is a noticeable rattle/vibration coming from the rear of the car.

It's not the parcel tray/rear deck where speakers are, but it's something mechanical.

I went through the FAQ and did a search, but I found nothing.

I'm thinking it is the differential bushings that are shot, or something loose in the rear suspension.

Has anybody else experienced something similar?

Thanks,Raj
