Rear Suspension Squeaking

[va01gtstang]

I already tried searching but didn't find much besides that it might be my wheel bearings squeaking. My rear suspension has constant squeak/creak everytime I drive. Especially if I have a passenger. I've pushed down on the trunk to see if it makes the noise and it does. Could it be my shocks or lower control arms? I have stock control arms and I Monroe Sensatrak shocks. Any help or advice?

Upper control arm bushings are usually the first thing to go, and one of the worst sounding too.

My stang did the same thing after the first summer i bought it.On mine it was the lower control arm bushings,where the lower control arm goes into the chassis(torque box).Everytime it would have suspension travel...it would squick,or if i got in or out of the car...it would squick.So what i did to solve the problem,is sprayed some WD 40 in that area to stop it,and it did.Maybe this is the same issue you have.
When i installed my aftermarket rear control arms,i lubed the hell out of them before i installed them just for this reason.

thanks for help. I was kinda thinking it would be the upper or lower control arm bushings.

Blast everything down with silicone spray as WD-40 will degrade your rubber bushings...

So will just rain water, or air for that matter But yeah, silicone over WD in this case. Idealy you should take the control arm off and grease it with either lithium (wont last as long, might eat away at the rubber) or teflon based grease (goooood stuff, but expensive).
