Car Swerves When Accelerates

[tuileihai]

After I had my car wheels balancing and alignment done, when I accelerated my car, it started to swerve light and right. My steering wheel had no control over it. It happened every now and then.
Where is the possible problem?

interesting. Please describe your problem more in detail to allow us to help

When I pressed on the accelerator, and as the car picked up, I can feel the whole car slightly swerving left and right on its own momentarily. It is an old Proton Iswara.

might be the steering rack bush.. it shrinks out over time..

But why right after balancing and alignment? Or maybe did not tighten something....:rolleyes:

 

[tuileihai]

Before I did my balancing and alignment, I noticed at times the steering shaking lightly and I let go of my hands from the steering wheel, it would slowly swerved towards the left side.

That was the reason I sent my car for wheel balancing and alignment. And now I found out this new problem. The swerving movement is as if my car being lifted up by strong gust of wind or speeding thru' a big patch of water on the road.

there is definitely something seriously wrong.

A quick video would help us help you identify the problem

Makes me doubt the quality of alignment work there as well.

Yup, probably need another shop or mechanic to check if anything is loose.....

TLH, go to another alignment shop to get a second opinion

Go get a 2nd opinion and redo alignment.

Initially I thought it was torque steer until I saw what car you drove then that thought went out the window. Unless you have a 4G63T inside?

And what RPM do you experience this swerving? Do you feel it even when driving slow or only when you accelerate hard?

Exact feeling right here, was deeply curious to know the powertrain but oh well.

Possible that your car undercarriage/sub-frame is very loose/flexing alot. I mean since you say is an old car.

But before doing got different problem then after doing the alignment

 

[tuileihai]

As I have mentioned before getting my car wheels balanced and aligned, my car would slowly steered towards the left side. After having it done, the steering wheel felt lighter. When I revved up my car, suddenly I could feel the car swaying slightly left and right momentarily. And I felt no control over the steering wheel. It was scary.

TS, EXACTLY what was done during allignment service?

I am beginning to think your car behaving like a pushing a shopping trolley with a busted castor wheels....

Check the steering rack for excessive free play or is it loose.....

Got the same prob few months ago just after alignment+balancing...in my case after adjusting the front toe the 'loose/light' feels noticeably less
