So some of us admitted to a very disturbing and loud squeak in our tc balts when going over speed bumps and when weather is below freezing...... So what is source of squeak??? Trailing arms? Swaybar endlinks? Bushings? Chassis? Also , u think low 13's with trap speed of 108 is possible with gms1 with muff delete??

 

Yes to all

 

I dont know if this is related, but its a shot in the dark. Check the subwoofer in the trunk. If you are running the stock subwoofer, those a-holes at GM didnt tighten the bolts down all the way so mine was making a "Metal running down a screw" sound and it bugged the hell outta me. Anyways, I hope I may have helped in any way. Good luck.

 

yay for GM quality control.. the SS sedan i almost bought before this one had the g85 option... but the turbocharged badge was put on upside down :/ lol

 

it may be the shocks mine do that but once they warm up the noise is gone

 

my front struts do the loud squeek all the time. i don't think anyone really figured out a solution for it though.

 

the first time it happen I got out and to look I actually thought my splitter/lip had come off LOL and was dragging on the ground .... I think it happens after they get wet and it is below freezing , very aoying but I am sure some special grease would work not sure what to use ..

 

Im 100% sure its the stock bushings that hold the sway bar in place... Theres a fix for it when you bring your car in, they replace the bushings however you may be compromising performance... deal with the squeeks its only cold for a few months, lol. This was covered in another post on here but I forgot where.

first time I heard it too that is exactly what I thoguht!!! lol. I used to have a lowered car so I know what that sounds like when it scrapes.

 

i drove beside my friends g6 with window down in fall, his does the same thing, just not as loud.

 

I silicone lubed all of my sway bar bushings and the car still squeeks. I think its a combination of a few bushings and maybe even the spring isolators.
