About a month ago I started to hear a squeak coming from the rear of my car. This squeak does not happen all the time though, only over certain bumps and when the car shifts gear. My stang is a 2007 v6 incase that has anything to do with the problem. I really need help the squeak is driving me nuts. Thank for any help you can give.

 

Squeaks and rattles drive me nuts. Can you approximate where it's coming from? Maybe have a friend drive while you crawl around in the back seat and listen. Try and find out if it's coming from outside or inside the cabin or in the trunk.

 

muffler hanger bouncing maybe? suspension link? brakes?

 

The squeak is definitely coming from the outside of the car and it sounds like it is underneath the back probably near the axel. Other than that i don't know where its coming from and its really annoying me.

 

What kind of squeaking noise is yet? I periodically hear what sounds like a hanging chain coming from the passenger side rear end, and have yet to find out. I've also recently been the recipient of a very obvious "bed spring" squeak coming from the rear driver's side wheel well when people get in and out of it. Still trying to figure both out.

 

The noise is coming from the rear lower control arms and check the diff bushing as well.
The upper control arm will do as well. Normal wear and tear after 50k.

 

The seats will make a squeak noise if interior. Exterior just check the rear bushings, rear lower control arms and the rear upper control arms.

 

It's definitely coming from the exterior. It sounds like I have a goose trapped in the wheel well whenever someone gets in or out. I'll check the above this weekend and see what's going on.

 

Is it a pony package? If so check your rear sway bar end link bushings, as well as all the other bushings LCA's, etc.
