My car is lowered on tokikos and springs. everytime i hit a bump on passenger side front wheel i hear and loud bang. is that mean my shock is out?

Thanks in advance!

 

Could be. More likely is that the car is pretty low and that your bump stops have disintegrated. The sound you would be hearing is you upper control arms hitting the towers and/or the steering tie rods hitting the frame.

A better description of the car and setup is necessary if you want any actual advice. It's really only an educated guess that we're talking about a Honda instead of an 87 Chrysler minvan here.
