I've got a 1993 K1500 Silverado with a front tire bounce problem. When I go over several small bumps at once (train tracks usually does it) the left front tire doesn't want to stop bouncing. I figured it was a blown shock and replaced the fronts but it hasn't stopped. Anyone have any other ideas? Thanks.

 

Is it bouncing up and down or is it shaking side to side (shimmy)? get under it and have someone crank the steering wheel back an forth while you look for any play.
