I am starting to get a sticky steering wheel in my 13 plate leaf. By sticky I mean that it's kind of jerky when turning it, like it's not smooth. I will hear a small grindy noise from the steering wheel and it feels unsmooth when I try to turn the steering wheel. In the last year I have replaced, tracking rods, wishbones, drop links and had wheels aligned and balanced. But it is still there. Any ideas what could be causing this? Could it be eps? I read that some BWMs have EPS that turn of briefly when the weather is hot say above 18 degree celcius and this seems to happen mostly when the weather is quite hot outside, so maybe it is that? Anyway anyone elese have this problem and what did you do to fix it?
