Okay so i have had a bad squeaking in the rear for the past year and finally getting tired of it. When i go over small bumps, up my driveway or down or over turning slow i hear creaking in the back. Basically when teh rear suspension is being moved. I push and pull up on the rear and can hear the creaking.

Sprayed silicon on teh bushings to see if it would fix but didnt.

Bad shocks?
Bushings?

 

When you sprayed the bushings did any of them look torn? If not, I would suspect that your shocks are done and need replacement since you have 89K miles.

 

You didn't state which bushings your sprayed, so which did you spray? The noise your describing is sounds like its comming from the rear swaybar-to-frame bushings. I think if you have stock suspension, you can spray them with silicone lubricant. If they are aftermarket swaybars, you will need to remove the bracket and bushings then lubricate, and re-install.
