My rear suspension is making a loud creaking sound when I go over speed bumps. It started about a week ago but I'm not sure what is causing it. I swapped out my trd springs/shocks about a month ago with my factory springs and snow tires. The only other mod is a trd rear sway bar but I know that can't be the problem. Any ideas what could be causing it? I'm planning on oiling the bushings this weekend but nothing else looks wrong underneath. I have 29k miles on it.

 

same to me.. not always but sometimes i can hear that.. it might be the hatch rattle...
i dontknow.. oh i have tokicos and hotchkis

 

After I oiled the rear bushings the sound went away completely.

 

how did u do that? wich part is the bushings?:D

 

i have the sound too.....tein s techs. i hate the creaking noise! and sometimes when i'm turning up a hill it feels/sounds like my entire roof is about to shatter. could it be from the suspension?

 

Well it didn't seem to work. It started back up a few days later, so I have an appointment with the dealership on Saturday since it's still under warranty. I'll let you know what comes out from it.

 

I'm placing my bet that it's just from the rear sway being set at "race", and if you set it to "street" it would stop creaking.

 

Why do you say that? I did change it from street to race when I took out my trd setup just before it started, so I was thinking the same thing. But just curious if you have any info on why that would be?

 

It's just part of the nature of a stiff sway bar. As you remove the independence of the rear suspension, you'll get some creaking, especially when you go over uneven bumps (like driving over a speedbump diagonally). There's nothing wrong with it, as long as you don't break the end links (I think that's what they're called), which you shouldn't with a TRD sway.

 

It's an especially loud creaking sound, and even moreso from the outside. I'll maybe try to change it to street and see if that helps. Thanks for the info.
