Check the motor mounts. That was my problem, after checking everything else.Hi guys as my name suggests I am British, moved to Canada and eventually bought a Truck which I said I would never do. Truck cost me $1k as the move crippled me financially and I needed a cheap run around. $13k later I have a mostly restored it which I said I'd never do, done everything I think would help to make it a better truck and most of the things I've done haven't made a difference. Recently I have noticed a vibration that feels nothing like an out of balance wheel, its a very fast but not overwhelming vibration over 70Kph and feels like I am going over a rumble strip in the road at speed (Rumble strip is a British thing, that's why I mentioned I am British, designed to slow you down). I just wondered if anybody else had this issue or any ideas on this sudden new problem?
