I am running a 2004.5 dually 1 ton, skyjacker 5 inch lift. Driving with light left to right turning i started to feel a slight knocking sound and feeling that sounds and feels like it is coming from steering shaft.this started about 6 months ago.The lift was put in 1 month ago. Steering now feels like it is starting to get worst " wondering". The knocking sound is getting worst. Anyone have any suggestions. Is my steering box ajustable?
