Can be everything, wheel bearing, control arm bushing, unbalanced wheel
I had a car once that I think I was told one of the rims was slightly bent. It consistently had a vibration at high speeds past 100Kph. I never did really figure it out. Most other times vibration has been due to the tires, in my case.
I'd like to see a modern car that wasn't designed to go much past 60 miles per hour (acc'd to Google). I'd be like, well you're taking this car back, buddy.
How bad is the vibration, and do you feel it primarily in the steering wheel? I've had tires where the tread began separating, on more than one occasion, causing the tread to have a wiggle in one spot.
but that you also might feel as a wobble/wiggle at low speeds, if it's bad enough.
Aluminum wheel, steel wheel, aftermarket wheels ?
Vibration is end result of something in motion that when the harmonics come on right, we can feel something..
Wheels, bent lip, flat spot bend from impact with curb or pot hole
Tire balance,, how was they balanced ?? Ideally 2-Plane balance with weight measure on planes as far apart as possible
Engine,, nope,,,, stand on throttle and rev it up,, does it shake
