98 s90 shimmie freeway speeds (65-75) while going right .

[steelbox]

when i go on the freeway and following the freeway to the right at freeway speeds i get a shimmie not sure if it the right side or the left. I think it might be the left front. could it be an idler arm or something in the front end. other wise the car turns fine at lower speeds and feels tight and no clunking sounds. Thanks
