I cant figure out wats wrong wit my g35...the problem is when i hit 70 on the freeway my car starts jerking left and right from the front tires. If i were to let go when it jerks i would probably lose control. i literally have to hold it in place but all i feel is the car wanting to jump left some times right but once i hit 80+ it goes back to normal????

 

That's really something we can't answer for you. What are the condition of your tires? When was the last time you had an alignment done?

Also, what's the condition of your suspension? Anything loose or knocking?

Are you lowered? Excessively? Tire sizes? Are you tracking ruts in the road?

 

jack up your car and see if you can move the wheels around with your hands

 

Could be your lcas up front our cars wear down some what fast and the lca gets completely disconnected from the bushing causing it to move back and forth about 2 inches. Jack up your car and hit the body side of the control arm and see if it moves. This was the problem with mine and 3 of my friends. Try doing a buck 20 and have your car do that😱

 

My tires are almost new, got my alignment wen i got my tires less than a month ago. Im not lowered. You think it could be my lcas thats what it feels like just jumps 2 to 3 inches to the left at high speeds 65+ mph but once i hit 80 everythings smooth

 

Could be doesn't hurt to check either or possibly your hub bearings or maybe something just loose under there. Just gotta get it up and check. Make sure all your lugs are tight lol

 

Either bring it to a shop, of find a nice day to get the front up on jackstands and start going through things
