I just had a new set put on about 4 months ago and it had the same shake to it before and after. It seems definately be coming from the front yet only shakes the steering wheel a little. for got to mention before I noticed while crossing some reflectors on the freeway that were closely spaced the frontend seemed very loose and made the same kind of shaking just more intensified. Yet everything is tight and I still get times were it still cruises smoothly at the same speeds.
