Vibration at speed - SimonJ
I have noticed that when driving at speed 70-80mph I have a small vibration felt through the steering wheel.

Any ideas what it can be? Balacing, tracking or something else?

Probably. That'll be the easiest thing to have checked first.

I do not know how old your car is but after balancing,wheel alignment I would check the driveshafts.
