with my hands on the tire, wheels locked, it moves back and forth left and right, its suppose to be stable and not rock, would this be the reason why my front tires are losing a lot of tread on the inner walls? or do i need a whole lower control arm?

 

 

i have a 93 civic coupe and had the same problem.
yeah you got to change the bushings, not the arms.
if you keep that way it will probably eat up any tire with in a couple of week.
if you change the bushing, make sure you change them for both arms that way you dont have to worry about it any more, it something that doenst happen very often
