    I have a low vibration coming from...

    ...the rear of the car. I only happens at low speeds. I've checked the suspension, tranny mounts, exhaust pipes and everything seems tight. Any ideas?

    Only major vibration/rattle I've had from the rear was a U bolt coming loose on my exhaust, the guy putting my cut-outs on spotted it and fixed it. Does it sound like it coming from inside the car, plastic maybe, or from the exterior?

    Exterior of the car. The sound is more so while backing or turning at low speed like in and out of driveway.

    Hey 01LS1,

    Can you describe the noise with a little more detail please. Like, is it a clunk, rubbing sound, or maybe a metallic sound? Is it rotational? Etc.. Also, do you notice it changes over bumps or on turning - regardless of low speed situation?

    I think I know what you're talking about, mine does that too...
    I can't really explain it, it's a very... solid, low vibration.
    By solid I mean it's more like a heavy buzz than a swaying vibration. It doesn't pulse, it's just a persistent vibration.

    I had a vibration/buzzing sound and it turns out that when i had the rear diff serviced, they didnt put any posi-lock in the fluid and the clutches were making noise.

    any kind of rear end vibration while turning is usually diff clutch chatter. gotta use the friction modifier.

    when was the last time you checked the tightness of your lugnuts? it could also be that one of your tires is unbalanced
