when i'm in the fwy and i'm going like 50 miles the car starts shaking side to side
why is that ???

 

have you hit a curb, went over tire speed rating ? check your tires for a broken belt. and check to make sure they are balanced. peek vibration from out of balance wheels happen at 55

 

You'll have to explain better then that, is it coming from the car the wheels or what?

Few possible reasons.

 

well i got the car a few months back and i barely took it on the freeway and it started moving side to side , and the tires are brand new , can it be the brushing in the back ??

 

Can be a bunch of things, it started happening really doesn't clear up much.

Alignment, brakes shot, bad bushings and front end problems. All are possible.

 

well it's clean title , the brakes are brand new
will this help ? http://www.summitracing.com/parts/PTP-8-304-BL/

 

alignment maybe but that'd be at all speeds so wouldn't a front end problem, brakes you would feel a pulse or pull, broken belt in a tire you'd feel at low and high speed... hondas are light sure its not just the wind

 

well i just check the car and the rear lower control arms are gone..

 

Elaborate on what you mean by "gone"

 

broken already

 

i agree and nice title mig

 

check your swaybar end links

 

get a wheel balance and tighten your lugnuts
