So I just bought a 2008 Cobalt SS, and when driving it home(110 miles from the dealer) I noticed anywhere 55-70 MPH the steering wheel shakes. But just those speeds - I can not imagine this is normal.

Also, the engine has a slight tick. It has 91 octane gasoline, so i know it is not the knock from octane. I can't imagine this is normal either.

The car is going into the dealership for some paint issues i addressed before i bought it, but I would like to know ahead of time some ideas of what these problems could be... Thanks!!

 

IDK about the steering shaking. Mine holds up perfect even at 80mph. I believe the ticking is normal (direct injection).

See the post below.

Congrads dude.

 

ahh ic. Thank you! Does anyone elses tires look like they are bulging off the rims? the car says the PSI in all 4 tires is 39 PSI and the recommended on the door is 33 PSI, would this cause the car to shake at those speeds?

 

Steering wheel shake is an umblanced wheel...I had the SAME exact problem

 

no problems here with the shaking

 

What u do? How many miles when it happen?
Thanks

 

i concure went to discount 4 times to get a rebalence they finaly had to to a precition balence thing on the wheel to finaly get it sorted out

mine still dose it. i need to get back into the shop and have a rebalence again i think i threw a weight

 

soo this should be like a warrenty thing? I mean I have owned the car for a week!

 

Once again the ticking noise is the direct injection nothing wrong there.

 

They are designed that way to protect the rims .
They call it scrub gaurd I Think

You should take a quick look at the rims to see if you can see a spot where the wheel weigt might of been,

 

the noise is normal i thought the same thing. I work at the dealership i called the tech line and they said its normal. as for the tire set the tire psi to spec the lip is to help guard the rim for u scraping it.

 

same problems here...ticking is normal

the tires are all out of balance straight out of the factory...get your dealer to balance them for you...i did and i have no problem anymore

 

Yea my steering wheel shakes at those speeds as well, I was just going to have the dealership check it out on my first service.....

 

i had that same steering wheel shake that your talking about. but after a bad wreck and a new front axle and new suspension, that problem was fixed! lol

 

I had a shake in my 2.4, dealer narrowed it down to a bad balance, but refused to warranty it, claiming abuse after 4 days of ownership Bad *alignment* might be my fault, but balance should definately be a dealership's problem. I'd take it in and at least ask, hopefully you have a good one. Coming from a guy that went from full warranty to no warranty; use it while you have it.

Nothing like a good old fashioned wreck to fix things, worked for my Firefly too

As for the tire lip I noticed that on my SS/SC, I have 3 Pirelli PZero Rossos with a decent lip on them, but my right rear(the quarter panel that got replaced) is a PZero Nero, is there any difference? The tread looks pretty much the same, just no lip, if it costs me a rim I'll bring pain to the used dealership.

 

I NEED TO FIND WINTER RIMS FOR THE SS TURBO COBALT AND WITH THE BREMBO BRAKES BEING SO BIG I MIT HAVE A ISSUE WITH FINDING SOME TO FIT ANYONE HAVE IDEAS LET ME KNOW ASAP PLEASE JSLOZON@HOTMAIL.COM

 

The Nero is an all-season tire, where the Rosso is summer only. It's softer and has less cornering grip than the Rosso. I'd recommend at least getting another Nero for the other side, but better yet to replace all the tires, or the bum one with a new Rosso.

 

I think 70% of the time if you have a shake is going to be wheels out of balance. 20% of the time it will be tire issues, 10% other! Obviously unless it happens when you are braking then it would be 90% of the time warped rotors, 10% other.
