1999 Chevy Silverado front end shake

Hi rgaden,
Well, first, have you had any brake, suspension, or other front end work done recently? Is the 47,000 miles correct? That's low for a 99 so I thought it might be a misprint. Also, does the shaking get worse if you down shift and increase engine rpm suddenly? I also wonder if you are getting a brake induced pulsing that you are calling a shake or is it a hard shake?
