Like title says however I know most are goin to say warped rotors which I recently had. When the rotors were warped the wheel would shake horribly at 70 and not at all at 40. Within the last 1500 miles I had the rotors turned. Within the last tank of gas or so the shaking has returned however at 70 the brakes are completely smooth when braking from 40 to 25 the wheel shakes. Is there something else other than the rotors that could cause this ? Oh by the way I have a 07 sc/ss

 

out of balanced wheel.

 

^^^ This, or improper torque on the lugs. Worth breaking out the torque wrench and retorquing them.

Could have warped the rotors again too, going to be easier to do after you remove material by having them turned.....

 

Get your tires rebalanced. Also make sure they're aired up.

It could also be a problem with road force variation in the tire. Overtorqued lugnuts won't cause a vibration.

 

This is normal. Same thing happened to me. I'm on my second set of rotors now. When you turn them they warp that much faster. I got about a week between turns on mine.

 

replace rotors and pads at the same time get wheels balanced and see what happens if it still shakes have your front end inspected and check lug tq specs. I use a tq stick specified for smaller cars like ours so not to over tighten the lugs which can cause warping to the rotor(s) try out what we suggest and report back.

Good luck,

i have the same problem and some people told me if its not the rotors maybe the sway bar linkends that im in the middle of lookin into.... alignment or maybe your hub bearings i replaced them it stop all noises and doesn;t shake has much but im in the same boat if you figure it out let me know please lol ahahah

 

i got a 08 lt cobalt that is perfect never had any problems except.... the f*(kin SHACKING!!!..
i got both new front brakes drilled n slotted, ceramic brake pads, two new front end hub bearings had wheels were balanced n weighted. got new back brakes to just because...People tell me that its my rotors but they brand new and i keep money into it and it keeps shacking .... could it be my SWAYBAR LINKENDS-ALIGNMENT!??!!!....can someone please help me i got air and everything is good but it wont stop shacking and i dont know what to do but at this point im gunna trade in .... cause i love my car but cant stand it at the same time!!!!!!!!!!!!

 

Try pulling the fuse for the abs and see if the shaking goes away.
Just something to try.

 

No offense, but no. I am a certified mechanic and that won't do anything.

First check tire pressure, if ok then take the wheels off and inspect pads, rotors, and calipers. You could have a fluid leak or air in the system which will cause pulsating peddle and or shaking.

good luck.
