yea its stock suspension the car leaves stright and the starts driveing i moved every thing back then made the upper right bar longer by moveing the upper bar one flat im testing agine tursday lets hope this helps thanks for the adviceIf you shortend the right upper you moved the rearend to the drivers side by doing so ! I would put the right side back where it was so the rearend would be back centered and then i would put a 1/2 of turn of preload on the drivers side antiroll link and the car should leave straight and stay straight! I am assuming this is a stock suspension malibu ?
how/ what do you know what is too much or too little? do you want it neutral on the scales or offset the weight of the driver with passenger preload?You need to check a couple things:
Make sure your rearend isn't bent. One tire or the other sometimes will toe in or out causing all kinds of goofy things to happen.
Make sure your rearend is aligned straight. You might need to adjust a rear lower control arm in or out to make sure the rearend is straight with the front alignement. If it's off, it'll make a car go left or right too.
Rollout on the tires being off. Switch them from side to side maybe.
ARB... if everything above is good, you might have too much preload in the ARB or in the coil-overs. Scales will help you figure this out. If you don't have scales, shorten the pass. link on the ARB slightly to take preload out of the ARB. Too much preload on the pass. ARB link will drive a car left... too little preload on the pass. ARB link will drive a car right.
