If you have an issue with a bad radius rod bushing can that cause your car to vibrate while driving and shake some while braking? It looks like a simple fix, so i am going to replace them this weekend. Also, if your bushings are bad can that cause your struts to not sit straight?

 

It is an easy, straightforward fix, if rust doesn't interfere. Based on your limited info, I'd say it could be the cause of some or all of your problem, but I doubt it.
