I'm having some serious knocking going on in the passenger side front end. Even the slightest bump will cause the knock, but obviously the bigger the bump, the louder the knock. I have checked the sway bar links and all seems fine, as well as nothing being loose component wise. I may not have checked my CABs for failure properly, but what is the best way to decide whether the problem is the control arms or the struts themselves?? I cant replicate the knock by bouncing the front end, but I can hear air being released from the shock. The drivers side I cannot hear any air, which has lead me to think the main issue is the strut assembly. There is also a lot of knocking at highway speeds when I let OFF of the accelerator. Before I start ripping things apart and throwing money at it....do these symptoms sound more like one or the other?
