I had this annoying high pitched chirp that my car makes ovvasionally when going over bumps at a slow speed. It happens when there is a lot of bounce in the back of the car or if I am catching a lot of air going over a hill quickly. It really bothers me, and I am tired of blasting the radio. I have taken out the entire shock assembly out of the trunk and drenched the assembly in WD-40. Ideas?

Really? Nobody?

Come on.. you guys all have 4.6L mustangs with the same setup as me from the factory.

Yeah I have that too, but having the radio on will usually cover it. I almost always have my radio on so I never really hear it.

I have the same problem and have no idea what it is.

mestit3

me too. i changed the rear shocks and didnt make a bit of difference

vanquish

my one guess was the shocks but I guess not.

lol i havnt posted in so long but after seeing this thread I thought i remember that noise and how annoying it was untill i fixed it....


its the trunk latch against the metal latch hook. Put some silicone in the latch mechanism.

If you still hear the noise then its comming from something else.

Check the lower spring isolator, they can get pretty chewed up..,

Where is the lower spring isolator? I have shocks seperate from springs, is it at the base of the spring? I noticed this squeak occurs when the back is raised up and lowered back down, like going over steep, short hills and stuff. Hence, the low speed thing too.

Yup...
