Ok the light grip test had wobble left to right at 65mph and over , so took it to one place for balancing of tires they said nope, take it to place alignment was done as shake is steering up and down is attributed to bad balancing, not it shaking lef to right....took it to alignment place and explained symptom slight wobble of steering wheel (but can't feel it) left to right on a straight line at 65mph and over initially he said balancing but when he looked at tires (and don't stone me for not mentioning this at start of post) he said you have different tires up fron't with differing treads and its like you trying to walk with different shoes on each foot....no idea how true this is as in the past had the wobble to a much greater extent even with the same set of tires ....?
