'72 911S creaking sound under the body

[silver72S]

Hi, guys.
I can hear something creaking under the back seats after replacing the spring plate bushings this summer when I drive over a step. This was my first time to replacing the spring plates by myself. When I installed the bushings, I did not put any grease on them. Might this be a cause of the creaking sound? Any thoughts?
I appreciate your any comments or help.
Thank you.

Did you put in rubber bushings?

Yes, I put in rubber bushing onto the spring plate with glue.

I drove it on tight bumpy road and heard some creaking noise coming from around the spring plates.

Thank you

Disconnect sway bar and try again, if noise is still present disconnect shocks and try again, if noise is still present get someone to push down on rear fender while you listen underneath with a stethoscope, you should be able to pinpoint the noise source.

Thank you for your comments.
I will try to disconnect the sway bar first.
