I've already tightened the hatch bolts and tweaked the rubber stops. It's not the rear seat brackets and I've removed the spare tire.

What are some common things that I have not listed? TIA

 

take off your rear sway bar and grease the bushings up. I have heard that can cause some severe squeeking.

 

Yep grease up the bushings

 

This is definitely inside the car. Thanks for your thoughts though.

 

Maybe the speaker area? (sail panels?)

 

Could be. There is a styrofoam piece that is located under the speaker. I'll check it tomorrow.

What else ya got?

 

There is nothing else in the rear of the car on the inside. Just get a can of wd-40 and go at it. It might be two plastic pieces rubing against one another. Silicone anything that might be doing that. That stuff is awesome!

 

Spare tire and jack?

Is the antenna loose?

My rear DeCarbon shocks made noises like that right before I replaced them, FWIW.

 

you should check the side panels in the back, mine weren't tight and were rubbing causing a squeaking sound

 

i just bought a 99SS and there was a squeak that drives me crazy you hear it while moving slow not much at highway speeds traced it down to the pass side shock never knew a shock to squeak like that the wife calls it the little bird cause thats what it sounds like a little bird chirpping lol any ideas on a good low cost shock somthing around $100 a pair?

 

check on ebay for some bilsteins. a pair just sold for $125 I think. I just ordered a full set of bilsteins and it cost me $314 shipped.
