So for the last couple of days i have been hearing some sound coming from the rear suspension. Mods are yyz v3, powell hardcore bar, and konis. What do you guys think it could be seems like its coming from the springs but its really hard to nail it down any ideas are greatly appreciated.

sorry for the video idk why it came out like that

 

Any ideas?

 

My opinion... Something is fuckkked up lol.

Did you put the lower seat and upper one in there with the bump stop, when u did the springs?

 

Never heard that one before! Id say get it up in the air and uninstall/reinstall stuff haha.

 

Well i put back everything the way the oem ones had it. Im going to buy a stethoscope from autozone to see if i can get closer to whats making the sound, i just hope its not the torsion bar or something like that

 

Im actually going to re install my oem springs on the rear to see if its that. Hopefully its nothing major. While going high speeds its hard to notice but you can hear it every now and then. At low speeds i can for sure hear it better. Its not super loud inside the car but under the car as you can see its awhile different story

 

tighten up all the shock bolts? sounds like there's something slapping or getting caught on to the suspension. actually sounds kind of like cracked sheet metal flexing.

 

Yup everything was and should be torqued to specs. And thats what i was thinking, i thought maybe it was the exhaust but i couldnt move that thing at all

 

Anyone have any more ideas

 

Did you check the Twist beam bushings?

 

No where are those exactly?

 

 

Cool thanks man ill give those a check. Also now ive notice that lately when i do u-turns or turns a tad fast my tires are making noise

 

Yup i found the thread about it sure seems like it

Anyone know what tool is needed for the removal of the bushings? I know is the Kenmore one but thats about it

 

I have the tool if you want to rent it from me.

 

Cool sure i wouldnt mind still gotta check the bushings tho and order the new ones so we are talking about in a few weeks

 

just let me know

 

So i checked the sound again with my stethoscope that i recently got and its really hard to pin point the sound the whole torsion bar makes the sound lol.

When i checked the bushings tho i couldnt hear any clicking at all. I went ahead and checked my springs and the sound seems to be coming from them wonder why they would be clicking tho

 

Dead coils smacking

 

You think so? I thought it would sound different for some reason lol.

Im thinking of installing the oem springs just to see if it is the springs making the sound, but either way im going to buy the sleeves from CED for the dead coils

 

its the coils hitting you can see and hear it in the video. Idk why but all of the yyz pics i have seen, no matter if the dead coils are on the bottom or top, the springs hit when parked. Mine dont do that. There is a good amount of gap in between them.

Once i hit a tiny crack in the road though you can hear them clank. Its deff your coils hitting though. The silencers will take care of that. Mine will be here tomorrow, ill let you know how i make out.

 

Your little rubber seats for the coil may be worn out. Mine use to make that sound with different springs on my old cobalt so just check those out. It's the top on, it's metal underneath the rubber and when it wears out it makes that noise.

 

Yeah the top seat its pretty worn out aswell, or well atleast that rubber part is

 

So it seems like it is the coils smacking, put my oem springs for a day and i did everything that would make me heard the sound and nothing. Now the yyz springs are back in and i can def hear it again so ill be buying some coild wrap from CED to avoid the dead coils smacking each other
