204 awd SS shakes at 45-60 really bad need help

[Reese123]

I have a 2004 ss Silverado awe and I recently got a bad shake at 45 to 60 if I hit a bump the right way I will have to slow to truck to below 40 to stop it I’ve changed idler and pitman arm inner and outer tie rods and sway bar end links and bushings and I’ve had an alignment shop and they had no clue

I had a similar shake on mine but not as bad... I replaced my shocks and fixed my problem
