So I've never owned a toyota before, but after my recent marriage, i've come into possesion of HER 99 corolla. After starting the mantinence process that was neglected by others, when I get up to 65/70mph. it shakes, almost like a vibration. I changed the brakes and checked the rotors, they are all new and smooth. Recently I was told to check the bushings on the sway bar. After reading im now assuming there is a front and rear. The bushings are 9 dollars, and im pretty handy with cars so I'm intending on changing these on my own, just wanting to clarify that this could be the problem cause i dont wanna have to get everything out and taken apart then find out its not the problem. Also, if there is a way someone could kinda walk me through this process, i believe its just jacking the car up, removing a couple bolts, slip the new bushings in and then reassembly. correct me if im wrong please.
