Hi everyone

I have just recently bought a Chevrolet Silverado 1989 Crew Cab which has a Lift Kits installed onto it and sits neatly on 38.5 Fat Swamper Alloy Wheels.

There is however a problem with the Steering, it vibrates it shakes from left to right badly when I attempt to turn the Wheel whilst the Truck is stationary.

Can anyone shine some light onto what the Problem may be and how I can go about in solving it.

Thank you everyone for your help.
