Suspension problem
1989 Chevy Truck V8 Four Wheel Drive Automatic 125000 miles
----------------------------------------------------------------
I have a one ton chevy dually 4x4 with a straight axle. The problem I am have is when I am driving and go over for example railroad tracks or a small pot hole the front of the truck shakes to where I have to come to almost to a stop to stop the shaking. I can not find anything wrong with the front suspension. Nothing is loose . The tierod end are new and the leaf spring bushings are new. The tires are new and balanced. The upper and lower ball joints have no play in them. My question is can the ball joints cause this kind of shaking ? Or can it be something else causing this problem.

i wouldntput balljoints as the #1 cause of the vibration when driving over bumps in the roads.

i woudl suspect a issue with the steering dampner if equipped.

if the front end is out of aligned it could ruin the tires,and cause it to vibrate as described.


i would also suspect bad tie rods, they coudl be bent and have no play!

wheel bearins are good?
