ok im about ready to just give up because i cannot figure out what on earth is wrong, a few months ago up until the past 2 weeks I had a problem with when hitting the gas the car pulls to the right and when i let off it pulls to the left, this problem occured when i went to the 17 inch konig verdicts and got the control arm bushings. I thought the problem was maybe alignment so i went and got it aligned, problem got worse, replaced both front wheel bearings, installed hub centric rings, got the tires rebalanced and mounted, Car was flawless and the problem was fixed, now today its back again!
What the @!#$ is going on?

LOl, the front control arm bolts come loose if not torqued down right.
Happend to me. All fixed now.

remember when i asked, where was your torque wrench
but seriously. did you check em again? the bolts that is?
yea thats what i first thought it was, a arm bolts arent loose

When was the last time you changed your tranny fluid and filter?
Either that, Double check to ensure that you re-installed a cotter pin. The nut for the ball joint could be loosing and pulling left to right.
I used air tools on mine, but managed to loose the cotter pin...
First time i had to see my cavy flat bedded to a shop when i went out of town.
hmm my car does this

sorry to say, it could be a tranny output issue. is it only under hard acceleration. or is it anytime you push the gas?
try this

also it may be as simple as tire issues...something may have happened and one tire is bigger than the other now for some reason. or even out of round as well as the same prob could be one rim. rotate your tires and try that...see what happens.
I have just noticed that you have coilovers...if you have one set one thred higher than the others...you could definatly pull to that side under acceleration. just a few mm can make the difference.
The coilover height has been the same for 2 years this problem only started after the new wheels, a-arms
Tranny fluid was replaced 10,000 miles ago
Tires are same size, 3 weeks old, rotatin them did not fix issue
It is more noticeable with speed below 35 its barely noticeable the faster i go the worse it gets , the tranny issue would make sense, or the ball joints but event said they looked ok

Could your left front caliper be sticking?
it could be somewith the brakes , it could be the tires and the road surface your on
in some cases wider tires tend to follow groves in the road , depending on the tread design
caliper idea is certainly a possibility i wouldnt think acceleration would make it noticeable, the problem is on all roads not certain ones
1989 Turbo Trans Am #82, 2007 Cobalt SS G85
The caliper problem would always pull to the same side. And would be most notable under gentle braking (or letting off the brakes).
Tranny issues would tend to favor one side too. Although it could still be tranny issues.
I think it's the new bushings (bad from the factory), bent/damaged control arm, something loose in that area. Maybe a ball joint installed crooked. Something is putting one tire out alignment (for lack of a better word) with the other tire.
When you hit the gas, the left tire pulls ahead of the right tire, pulling the car "around" with it. When you let off the gas, the left tire falls behind the right tire, pulling the car "around" once again. So I'm thinking it's something on the left side.
Try this once: Park the car on a level(ish) surface, tires straight. Have a friend push the car so it bounces forward and backward (should be plenty of slop in the engine/tranny mounts to allow an inch or two). Watch the front wheels closely, see if there is any movement relative to the rest of the car.
i too would have to say that it probally is a manufacture defect in light of what you have said.
have you checked the wheel bearing on the left side? like cts said its something on the left and could be that something is sticking...like a bearing. i know that they are new..but oversized tires and "spirited" driving tends to wear on bearings, bad.
The new A-arms may have caster/camber problems. could even be something wrong with the balljoint mount. if you have your old a-arms...i know this is a lot of work...but you could just swap in the old units and see if the problem goes away. Also try and see if it happens with your stock wheels and tires...if you still have them. You could have just gotten a bad set of wheels. You know this can be caused by something as simple as overtight lug nuts...i doubt that is your issue...but just saying...as you know... that any little thing can screw up the front end.
when you got your front end aligned did you check caster/camber? Most shops dont even know what it is...let alone how to check it.
sorry i cant be more help than just spitting coulda wouldas...but there is just so much it can be.
both wheel bearings are BRAND NEW, i do know that when the old subframe brace was pulled off it was all bent up after I hit a deer, i didnt notice any problem at that time, it was also noted that the subframe was bent, i didnt get new a-arms i got lower control arm bushings installed the prothane ones
unfortunetely due to having the wilwoods stock rims will not fit, my lugs are super tight
1989 Turbo Trans Am #82, 2007 Cobalt SS G85
Hold on. You hit a dear. And your sub-frame (and probably other stuff) is bent. And your wondering why you have problems?
What else was bent? How throughly did you check everything, and I mean everything?

check your control arm bushing. my probe did the same thing and i checked the bushing and the where shot, replaced them and never did it again.

ok heres a timeline
Nov 2004 Hit deer- bent subframe brace and pulled some subframe - NO ride issues at all
Feb 2005 - Bent brace was removed , still not any issues at all
May 2005 - Readded subframe brace, replaced lower control arm bushings with the prothane ones, wilwood brakes, and 17 inch konig verdicts, THE ISSUE STARTED HERE NOT BEFORE
1 week later - got the car aligned issue did not subside
2 months later - noticed a-arm bolts were loost
3 weeks ago, replaced front tires, installed hub centric rings, tightened a-arm bolts, replaced both front wheel bearings ISSUE WENT AWAY
yesterday, nothing at all is loose and issue is back again

I'd find me a really good front end shop.
you may also want to check and see if you don't have a screwed cv joint. or a broken spline on one of the shafts.
does this prob happen at highway speeds (cruising) or is it just when you gas it?
yea its only bad above 35, the cv joint or something with the shafts would make sense also something else i noticed today when cornering the right front makes a ttttt ttttttt tttttt sound kinda like a baseball card in the spokes of a bicycle type sound
1989 Turbo Trans Am #82, 2007 Cobalt SS G85
dude are you DEFINATELY sure, its NOT torque steer?
that happens when you add power.....
thats the sound...although it may not be... cv joints make that sound when they start to go. on your mod list i didn't see an lsd...so i assume you don't have one, therefore you could have cooked one of your joints. and also w/o an lsd...torque-steer is definitely an issue, this could also lead to axle destruction.
