DB9 Rear Suspension Creek / Squeak. Any idea on causes??

[spmcevoy]

I have a 2005 DB9 Coupe with about 30K miles on it so far (and loving it)

I have a rear end noise that sounds like a creek or squeak or groan from the rear suspension when I go over speed bumps. It's most pronounced when I go diagonally up a driveway ramp (to avoid noise scrape) and each wheel on the car climbs the bump independently.

Is this a suspension bushing noise? I've been searching the forums and see the occasional mention of bushings freezing up in mounts, etc. Are there replacement bushings? Aftermarket options? Not a lot of aftermarket DB9 suspension stuff on the Internet that I've found so far.

Any advice you might have to share would be appreciated.

Quite often the rubbers in the anti roll bar "U" clamps can produce noise as they start to age. Easy way to find out is to slacken them off and then bounce up and down on the rear of the car.

Thanks for that, will give it a try.

Does anyone have any details about the notion of the control arm bushings seizing up?

How about sources for bushings (roll bar or control arm) that are aftermarket?

Thanks in advance!
