Default Car jerking to the left when I get on it

Everytime I get on the throttle and the trans downshifts, the rear jerks very hard to left and then back to the right, like I completely lose traction. Why is this? Stock suspension in the rear except for the poly sway bar endlinks. Tires are 295/35/18. Any insight would be appreciated

you might also consider a UMI sway bar.

Sounds like something might of worked it's way loose in the rear suspension or maybe a blown bushing in either the lower control arms or the panhard rod.

If you push the car side to side does it make any kind of noise?

My car does that little "two-step" on a full throttle 1-2 upshift...always has.

I have upgraded shocks, springs, LCAs, and PHB. Adding those parts did nothing to change this behavior.

Its always made a creaking sound since ive had the car, but its really only noticeable if I push down the rear of the car, sounds like a squeaky mattress. I sprayed some fluid film on all of the bushings in the rear and its been quiet, but I gotta do something about this whole jerking thing, its almost to the point of getting dangerous just changing lanes if i step on it.

Sounds like you have a bad bushing somewhere either on the lower control arms or the panhard rod.....
