SoloZ/SS

you rallied a Cobalt? The knukle broke and you expected warranty?

spaz

I raced a fiax x 1/9 with hoosier slicks for years and never broke any suspension pieces.It should be warranty. Especially if he was on stock tires. Weak ass knuckles.

SoloZ/SS

would you rally your SS? and when things broke on your Fiat did warranty it(probably didn't have warranty)? Hey I drove my Z24 for about 6 years on and off race tires and never broke anything, I am even running my Cobalt on Hoosier A6 in autocrosses on bumpy lots.

to the guy that rallied his Cobalt, how did they find out?

spaz

Autocross yes ralley no.
All I am saying is it should be warranty especially the guy that broke it on the street. I raced seen tons of Acuras and wrx's running winter rally x and no broken knuckles on they. Gm f up and made they too weak and they sould step up and fix the car.Just like the axles. Nothing broke on the Fiat and I don't think they ever had have Warrany

avenger09123

did my autocrossing today for the first time, 10 runs total....didn't have a problem...., although I was worried they'd break so I never turned my wheel as far as it would go....

I was on crate the other night and noticed the prices for these have gone up...sUkS

Damn it that blows. I wanna get these with my tax return money. I know WAY too many people who have broken their knuckles during normal street driving to take chances with mine anymore.

redSSBalt

Are the knuckles a problem on all the modles of the Cobalt? Or just on the SS/SC???

alleycat58

All models I would assume since they all use the same knuckles AFAIK.

redSSBalt

Have you replaced yours yet?? I want to try autocrossing and maybe a road course as well...If replacing the knuckles puts you in a upper class, is it worth it to do it?? How fragile are they??

alleycat58

For me it's safety before anything else. I know they've broken on people on the streets. I've done parts of 2 seasons of auto-x and 3-4 road course runs, put about 500 road course miles on the car and mine haven't broken, BUT, to me I'd rather upgrade the part than risk repairing a catastrophic failure. preventative maintanence > oh ****! repairs

redSSBalt

You are correct, I was thinking the same way actually. Will the officials of SCCA know if they are replaced or not??

GM STEERING KNUCKLES
The competition-only steering knuckles for the Cobalt, G5, and ION,
as specified in Service Information Document #1864485, also do
not meet the requirements of the Stock category.

this is on page 247 of the 2008 rule book...I am entering into my second season of autocrossing, and am prolly gona go ahead and get em just in case, better than havin all that extra stuff when/if they do break....If ur not in stock class dont worry bout it

qwikredline

breaking stock knuckles(unless you crash into a curbor something) is a non issue imho but if you race your car like me u check these things closely often...kinda like a nut and bolt check or a torque the wheels before you go out check ....lol

LittleStealthSS

I was under the car this weekend and after 94,000 miles... 2 seasons of Solo and alot of potholes and such... no problems here...

I AM planning on replacing them, but with the old style units since GM labeled the other ones as "for competition use", I can't use them in Stock class....

Helltime

Does anyone know if this affects the 07 models? I have a cobalt LS (2007) and i was wondering if my car is affected. I didnt see it in the link that was posted but maybe someone did.

i think there was a video about this on here yesterday

cDub

Idk where u got those numbers from? The gm dealership said 372 dollars and they could get them next day through their distribution center.

suburbanrobot

34K on the clock.... quite a few road course days and over a dozen Auto-X's and no problem here..... IMO you really need to beat the crap out of your car to brake em, otherwise they are faulty units.... I think if they were gonna break.... they would have checked out already!!!

Lino

Does this knuckle thing apply to 2008+ Balts? Because I was planning on auto-xing my car and reading about this has me very scared.

You sir are very fail.

aterminatorz

Wow that's it? No other warnings for autocrossers? What about your tires will go bald, you can scratch your wheels, you can get cone rash? Anything else?

Dirty25RS

so ur kinda saying you should just cheat and use them anyways?

to be 100% real about it, local events you'd get away with it.

but regionals? no, nationals? no you wouldn't get through impound.

I wanted to go to get knuckles for my STi that could take the punishment of 315 width DOT racing tires, I couldn't do aftermarket ones, but I think I can do stock 05+ STi knuckles. So if the newer cobalts have better knuckles you might be able to swap them based on update/backdate rules.

rallyracer

I say put on the competition knuckles...claim them as stock. There still a GM part and yes for the 08+ they came stock updated so...

Remember though...08+ SS/TC knuckles will not fit SS/SC.
