just recently started. at about 70 mph, steering starts vibrating and sounds and feels like a flat on front. does this about 1-2 minutes then stops. doesn’t do it every time and doesn’t to it at lower speed. so far, nobody has a clue. i did recently have front brakes changed (not sure if that would matter) HELP! This is making me crazy!
Wheel balance? Bent wheel? Wheel alignment? Worn CV joint? Unevenly worn tire(s)? Tire with tread separation or damaged sidewall? Worn tie rod ends? Worn suspension components? Any or all of these could cause this problem.
If it started AFTER the recent brake work I suspect something in connection to that.
