Yes it's when I'm driving not braking. The steering wheel judders too. I had all four wheels balanced at a reputable tyre shop. I don't know if it makes any difference but if I freewheel at those speeds there's no judder but as soon as use my accelerator pedal it starts juddering
I have a 2018 Renault Kangoo van. The problem is that it judders between 45 and 65mph. I've changed the wheels round and fitted four new tyres but it's still doing it. Any help gratefully received.
