my 318s collum would make a kncking noise when i hit small bumps or occasionaly while turning.
where the two steering collum shafts come together there seems to be some play in a vertical motion..atleast in my 318. so the two pieces of the collum would knock.
i dont have a fix for it..but if u take off the panel by the pedals and tr to shake things around to see if thats whats making the noise.
We all get the urge...Saturday early morning...nothing to do till noon...
