Firstly, control arms calling it a day at 39,xxx km's is a real stunner. This is just no mileage at all. If they are worn out indeed, then i reckon you gotta replace them anyways. So, get the front set replaced and it can eliminate one variable in the list of probable causes. Stabilizer bar being thought to be replaced is also a bummer. Unless it is bent beyond belief by some impact, it never needs replacement. Just needs the bushes replaced. That's it. Do enquire if this is the case. Keep us posted. Cheers.
