Car has all new control arms, tie rod ends and just aligned. The front end feels very loose especially when going over rough road and hitting the brakes. Driving over a crowned road I have to constantly hold the wheel opposite the crown to keep it on the road. On the highway it always seems to drift and I'm constantly having to fight it to keep straight. I dont think it is tires because it does this on both the winter and summer wheels. And it did this before I replaced the TREs and all control arms. Turn in feels very crisp and responsive. I've had 2 alignments done too and tech said all looked good both times. what else is there that could be causing this?
