V50 sporadic steering wheel treble

Hello guys, I’ve been looking for something here in the forum and I’ve already found something, but only for continuous steering wheel tremors when braking through warped discs. I’ve been having the following problem for a few weeks: I sometimes have steering wheel tremors, but not always. I have the impression that I sometimes feel very light trembling in the steering wheel without braking, but when braking is sometimes relatively strong, another time is then again nothing. emst, in the assumption that the warped discs make themselves more noticeable when you are warm, but strangely there seems to be no connection here. I drive a V50 D5 from 2008, have now about 112,000km down, could it be that the wheel bearings are over? MfG and thank you for your suggestions, Cris
