I finished up my front end rebuild with new PST polygraphite bushings, new tie rods,center link, springs,steering gear,sway bar etc and I still have an anoying shake/vibration on left steer. This condition existed before the rebuild. It is almost like something is hitting the frame or header. With even 30 degrees of left steer it vibrates. I have had the front end alligned and the car runs straight. Other than this very annoying vibration it is smooth (as a big block can be). Any thoughts? Thanks, Skip

Nobody?

When you steer to the left you load the right side suspension and unload the left side suspension.I would start by checking the condition/adjustment of the front wheel bearings.
Next, swap the front tires right to left and see if the problem switches sides.

I have brand new wheel bearings so I doubt that is it since it existed before the overhaul. I will try the wheel swap. thx....anybody else?
