I have a worn bushing on the right lower control arm that causes play when you grab at the tire when the vehicle is off the ground. Of course there may the ones in the uppercontrol arm or the one in the left as well. That is where I'd start. Also in my other car my rim is bent. See if any of yours are as well.
Tires and/or wheels out of balance?
inner tie rods bad at rack and pinion
65mph is faster (100km/h = 62.1mph).
55.4 seconds per mile at 65mph
More than likely a tire out of balance, or a tire with a defect. The tyrod end may also be the culprit.
had this happen too me 2 times could be brake rotors probly not though,if its kind of a shimmy and there is alot of play in the steering look at your outbourd tie rod ends. they have rubber bushings in them.check your tire wear too.
