im having problem with my car and i cant figure out what it is

more noticeable at higher speeds
when i start driving and i step on gas the car kind of jerks to the right
and
when i let off the gas after moderate acceleration the car jerks back to left

so far ive checked
tires pressures
alignment
and brand new tires (all same age)

 

Have you checked to make sure you dont have a bad wheel bearing?

 

How can I check that

 

I know this sounds silly but Hisham had the same issue and that was because his tires were put on in the wrong spots. On one side he had 245's in the front and 225's in the rear. Not sure how you're set up but make sure the right wheels/tires are in the right spots.

 

i had this happen to me, check your tire pressure!

 

I'd check for bad bushings in the rear also. Since it happens under torque, it narrows the problem to the rear. Could possibly be a problem with the differential.

 

not sure if you have the same symptoms, but I ended up needing new rear axels
