At speeds of 60 or higher I feel a vibration that seems to be coming from the driver side front wheel. Once I set the cruise it slows and then kinda goes away. Is this an alignment issue, or possibly a wheel bearing going bad?

 

check the tread on the tire, and make sure the wheel weights are still in position.

 

Wheels also require balancing every once in a while, especially if you skid to a stop or do a burnout. Get a firestone lifetime wheel balance warranty. You'll love it. Just walk in and tell them to balance the wheels whenever you like.

 

Could also be a bent rim.....

 

So are the chances of it being something other than a wheel bearing pretty good?

 

F'in YES MAN! My 70+ car-shake was an 8" long section of tread missing from a tire.

 

I doubt it is a wheel bearing. When my front driver bearing went, it was sort of a whirring sound but would not be audible at speeds such as 60 or higher because the engine noise would drown it out at anything over 2000 rpm really
