Annoying squeaky rear noise

Anyone else experiencing a constant rear end squeak? I thought it might be a dry bushing, had the car up on a lift and spray lubed every possible location. Any suggestions? Could it be inside air suspension?

Ironically, I have a 2010 Shelby GT500 with a similar rear end squeak.

Since yours is a 2008, according to your signature, and covered by warranty why don't you let the dealer take a look?

That's my next move...I thought someone else on the forums may have encounter a similar problem. It's definitely in the rear suspension...but nothing major.

Closest MB dealer is 40 miles away and was hoping to take care of it locally. Thanks.

Just had rear ball joints replaced on our 07 last week for squeeking noise under warranty. Not sure if your 08 will have the same issue but there is a service bulletin on the 07.

Thanks for feed back, Pesky squeak is very noticeable when you get in and out of vehicle. I'll get it checked out at dealer.

Did you get this fixed by the dealer? I have the same issue with out 07 and they have lubed some bushings, but it comes back. I figured I would check before I take it to the dealer.
