Front axle turning system bushings

[Nasser]

Please help!

I notice that my steering wheel and front tires are shaking when I make a turn on med speed, the front of the bus is shaking horribly and shaking will stop by slowing down and re-accelerating, my tires are balance and they are new. Some of the tuning guys have told me that I need to change the front system bushings.

Is there is any bushings need to be changed? and where are they? and where can I find them?

The guy notes that I need a bushing because when he changed my air bag suspension and wanted to slide the airbag underneath the chase, he notes that the chase does not land on the top of the airbag plate equally! 1 inch different from one edge of the plate to the other.

Any comments would be super help form me
