Ok, I'm experiencing this annoying bouncing(up&down) type vibration on my passenger front end. Note this only happens when traveling at speeds of 75mph through 90mph and its been going on now for about a month. So I'm thinking, maybe the wheel needs balancing so I take it to a tire shop and I have them to balance both wheels but to no avail I got the same result. Now its winter and I've changed to my winter set and it still bouncing. So I've eliminated balancing and the wheel isn't warped. You guys think its suspension related?? I'm just trying to get some ideas of what I may be facing, and if its work I can do myself, I'll skip the dealership.
