My 04 with 125K when I bought it, now 135K, when I drove over the pot holes or the bump the car want to change lane by itself, worst when it's rain. I know the bushings are won out, I want to replace them with polyurethane bushings, but I don't know the sizes of them; Is any body have done this? can you tell me how many bushings in total (trailing arms ,control arms)? and what 're their sizes? I appreciated the information.
