Squeak/Creak from the rear!
For a good while now i have had a bit of a creaky squeak from the rear of the car and
it has predominately been from the passenger rear corner but is now, it seems,
in evidence on both rear corners.
On very slow maneuvering with the car going backward and forward it creaks at the
point the car stops and if you were to push the corner up and down it does the same noise.
It is ok once driving as, i suppose, the car is not bouncing up and down to the same degree?
Is this a dry bush of some sort or do i maybe need new shocks on the back? maybe it is where
the springs seat? Just guessing here!
I thought about aiming WD40 around strategically bit by bit on different suspects to narrow it down to a non
squeak/creak situation.... good idea, or not? Once located i can renew as needed i would imagine?
Any thoughts on a "usual suspect"?

What condition are your bump stops? I don't think I saw it in your post but does it do it while turning too? The things I would check would be your sway bar bushings, shocks and springs, and bump stops. How many miles are on your shocks?1998 Trans Am WS6 - Phantom

You sure your y-pipe is not coming into contact with the upper pan hard bar where it crosses over/above the rear end?
I'd crawl under the car and look for where metal might be coming into contact with metal. The metal will be shiny.It's stock.

The shocks, i reckon, are the original so 48k
I would not imagine the bump stops as it creaks whilst stationary if you
push up and down on the corners.
Its an up and down issue but not to any form of limits or stops. Just a very light
push up and down and "creak creak creak"!!
The only turning involved is slow maneuvering whilst barely moving.
Inclined to think bushes rather than shocks but i don't know!!
Jon... Good thought as it is a new Y but i have to say i have been a bit lax in
dealing with this prob and it has probably done it ever since i have had the car so not
a new thing at all!!

All stock out back?
I have lubed bushing faces with Synthetic Caliper Grease before to quiet them down. You could also have a loose bolt in the LCA's or panhard that is allowing something to move around a bit more than it should. Easy to drop each arm, one side at a time, and the panhard to check things out when you get a chance.

Old and new could have been hitting. I would check that area anyway. Won't take but 15 seconds. Aside from that, I'm not aware of any common noises back there. Jeff and others have given good advice.
Also check to ensure it's not your hatch. There's rubber stops that can be adjusted if the hatch lid is not closing as tightly as it should.

Could also be the rear sway bar bushings where the rod actually pases through the bushings. As you have already mentioned, the WD40 trick is where I would start though.

Thanks for the input guys,
I will get busy at the weekend to narrow this problem down.
